When the program evolved to include other paint file formats, its name was changed to VPIC. See the revision history in Appendix A for latest additions and bug fixes. Look at the section titled How VPIC Operates for an explanation of the differences between VPIC and other viewers, and the advantages and disadvantages of both types. The picture on the index page shows the screen you get if you just enter VPIC in a directory that has viewable files. The top row tells what SuperVGA card and how much memory VPIC thinks you have (you should configure VPIC if this is not correct), the filespec VPIC is using (ie, *.pcx), and is also where the Lock/Auto/Norm and Wait indicators appear (shown in italics). The second row is the the resolution line, with the current resolution hilited; you can chage resolution with F5/F6 or by left clicking with the mouse. The next 20 lines are the alphabetical listing of the viewable files; you can use the cursor keys and Enter or the mouse to select one for viewing. Line 23 is the Dialog Line where info and prompts appear; at the end of this line is the amount of free memory that VPIC can use for slideshows. Line 24 and 25 list the more common commands available from the menu; these can also be left clicked with the mouse to activate them. Pressing F1 gives a help screen of additional commands, and these can also be left clicked with the mouse to activate them. There is much more to VPIC, but this quick overview will give you the flavor of the program. GENERAL FEATURES - VPIC is a very easy to use but powerful file viewer and converter. It shows pictures in EGA, MCGA, VGA or SuperVGA video modes on most of the popular display adapter cards, and uses a plain text configuration file to tell VPIC which VGA chip your display card uses and what video modes it can do. It has a single file, slideshow, and menu mode of operation, and will show pictures in many of the popular file formats. When a picture is on the screen, except in slide modes, VPIC can manipulate the picture, or convert the picture to other file formats. All this in a fast, easy to use program that puts you in total control, and is rated by users as the top in it's class. It supports 32K and 16.5M color modes using the Sierra or ATT DAC's for viewing 16 thru 32 bit files in PCX, TGA, and TIF formats, and does color reduction (to 16 or 256 colors) for these file types if you don't have a hi-color DAC. Sorry, but VPIC doesn't work with 24 bit BMP's yet. MENU MODE - This is the default mode when you just enter vpic from the DOS command line. It lists all viewable files in a 4 column menu with easy to use controls to allow you to show pictures the way you want to see them, including a slide mode. See Menu Features. SINGLE FILE MODE - This mode has advanced features which make it attractive for application programs which don't have the ability to display hi-res graphics, such as data bases. You can shell to VPIC with a filename and the /r option to display a picture and return immediately to your application, without waiting for user input or displaying the shareware message. If you want user input, call a batch file containing 'vpic /r %1' and 'wait 100'. Page 2 SLIDE MODE - This mode uses a plain text command file listing the pictures you want to see in the order you want to see them, with mode and delay specs if desired. This is particularly useful to showcase your product line at trade shows, or to put on a self running demo. See Slideshows. IMPORTANT: VPIC requires DOS 2.0 or up to run from the current directory, or DOS 3.0 up to run from anywhere. You must configure VPIC for your graphics board using CVPIC or CONFIG; VPIC comes configured for a Tseng ET-4000 SuperVGA board with 1M memory). The WHICHVGA program will try to identify your VGA chip and the amount of display memory. See CONFIG.DOC. The Graphics Interchange Format (GIF) is a Service Mark owned by Compuserve. For further information, please contact: Compuserve Incorporated, Graphics Technology Department, 5000 Arlington Center Boulevard, Columbus, Ohio 43220, USA SUPERVGA BOARDS SUPPORTED - Presently, VPIC has SuperVGA support for the following SuperVGA chips (see CONFIG.DOC for details): * Ahead (A & B chip) * ATI New, old, and Ultra boards. * Chips & Technology * Cirrus GLD54xx boards (thru VESA) * Everex * Genoa * Headland/Video7 - Newer/older Video 7 cards. * NCR - used in newer Boca boards. * Oak * Paradise/Western Digital - Newer/older Paradise cards. * Primus - Used on Galaxy SVGA boards. * QVision - Compaq's video board * Realtek - used in Realtek board. * S3 GUI Accelerator - Doesn't use VESA info info is wrong. * Trident (8800BS/CS and 8900) * Tseng(ET-3000 and ET-4000) * Zymos - Used in HiRes VGA boards. * All boards that support VESA 1.1 and later correctly. If the info returned by the board is incorrect, a generic VESA config file is supplied, and you can configure with this and do 'vpic /v' to make VPIC ignore the incorrect VESA info the board returns. This VESA config file contains all standard VESA modes, and you can add/remove semicolons to make it conform to your display board capabilities. It works for most VESA boards, but may have to be 'tuned' for some boards if they don't use standard bytes/line, etc. your display board capabilities. It works The CONFIG program semi-automates the configuration process. If your display board implements the VESA standard (thru BIOS or a TSR), this will be auto-detected and used regardless of the configuration; the only drawback to VESA is you can't scroll down quite as far. The /v command line option makes VPIC ignore the VESA info your display card returns, and use the configuration info. See CONFIG.DOC, README.1ST, and PROBLEMS for more info on configuration. FILETYPES VIEWED AND CONVERTED - VPIC will view and convert to the following file formats [convert command while viewing in brackets]: Page 3 1. Binary Image Files (BIF) from B&W image capture boards. Display only. 2. Dr. Halo CUT files (with PAL if present). Not Dr. Halo PIC files, which are display adapter specific. [C] 3. GIF87a and GIF89a files; saves to GIF87a format only since GIF89a stuff is mainly animation and text handling enhancements. [G= normal], [I=interlaced], [M=mirrored], [U=upside down], [<= rotated CCW 90 deg], [>=rotated CW 90 deg]. 4. Deluxe Paint LBM (or IFF) files, regular and enhanced. [D] 5. MacIntosh MAC files. Display only. 6. Pictor/PC Paint PIC files. [P]. Some ViewPoint files. 7. Zsoft PCX files (including 256 color files). [Z] 8. ColorRIX/EGA Paint SCx files, uncompressed only. RIX wont tell anyone his compression algorithm, so compressed files can't be done. Use ColoRIX's RIXLATE to uncompress SCx files that are compressed. [R] 9. Targa 8 thru 32 TGA files, compressed or uncompressed. Also uncompresses Targa files that are compressed (e option while viewing). Now supports the Sierra DAC in 15 bit color and ATT DAC in 24 bit color, but file conversion options don't work from viewing screen. [T] 10. TIF files, all types except multi plane and FAX. [S] 11. Microsoft Windows 3.0 Bitmap BMP files, compressed or normal. [W] MENU FEATURES: * Handles up to 2000 files using mouse or keyboard. * Gives 4 column menu of files with extensions VPIC recognizes. * Arrow keys, PgUp/PgDn move thru menu. * Starting letter (or number) of filename jumps to files starting with that character. * Shows file at cursor with ENTER or left mouse button. * Mark/unmark files for viewing with SPACEBAR or right mouse button. * Shows marked files singly (ENTER or left mouse button) or like a slide show (F2) in the order marked. * [F1] gives help. * [F2] shows marked files like a slideshow. * [F3] gives file size, colors, and other info. * [F4] toggles between 16 (EGA) and 256 (VGA) color modes. * [F5/F6] decrease/increase default resolution. * [Alt F6] shows all 16, 256, and hi-color modes VPIC thinks you have. * [F7] Locks current resolution, or selects auto resolution mode. * [Alt F7] locks a hi-color mode if your display card supports these. * [F8] Makes multi-image GIF's pause for a keypress between images. * [F9] prompts for new path. * [Alt F9] gives a directory tree in the menu window. * [F10] shows current path for files. * Alt_C copies tagged files (or file at cursor) to a new path. * Alt_D prompts for new slide delay for slideshow (F2). * Alt_L prompts for new fixed margins. Entering 'a' makes that axis auto centering (default). * Alt_M moves tagged files (or file at cursor) to a new path. * Alt_S makes a slidefile of the current marked files. * Alt_T (tag) marks all files. * Alt_U (untag) unmarks all files. * Alt_X deletes tagged files (or file at cursor). Prompts for each file; Y deletes the file, N doesn't, ESC aborts the delete operation. * Alt_Z toggles the name display while decoding on/off. Default is on unless /z passed on DOS command line. * Menu text color setable in configuration file. Page 4 MOUSE SUPPORT - All the above functions are now controllable by the mouse. Click on the resolution bar, bottom 2 lines of quick help, or files. For the menu screen, the left button is the same as enter, and the right button is the same as the spacebar. While decoding, the right button aborts; while viewing, the left button returns to the menu. Most of the Alt functions must still be done by keyboard or from the help/menu (F1). The Alt_F9 (directory tree) can be done by mouse from the file menu screen. MENU LAYOUT - Menu lines are as follows: Line Contents 1 Gives the board type along with the number of colors (16 or 256). Toggle values also appear on this line (Lock/Auto, Wait). 2 Gives the resolutions available with the default resolution highlighted. 3 - 22 Four column menu of files with extensions VPIC recognizes. 23 Prompt and message line. Free memory displayed at far right. 24, 25 Quick help on commands and mouse menu. COMMANDS WHILE VIEWING - The following commands (shown in brackets) are available any time the picture is on the screen. * Shows filename while decoding, and [ESC] aborts decoding. Menu Alt_Z or command line /z overrides. * / or ? or clicking the right mouse button gives a help/menu overlay. The desired command can be clicked with the left mouse button or the key can be pressed to activate the command (except for F1-F10). * [A] animates a picture by rotating the palette; very pleasing for fractals. SPACEBAR pauses the animation, ENTER stops it for further commands such as conversions, and ESC returns to the menu. Up/Dn arrows and PgUp/PgDn increase/decrease the animation rate. * [B] converts a 256 color picture to 64 gray shades. 256 color modes only. Alt_F10 doesn't undo this, since all screen indexes were changed. * [E] expands a compressed Targa to disk for use by other programs. * [F] prompts for another filename and x,y margins; gives picture in picture. Works best when VPIC invoked with /m, /x, and /y command line options, or with Lock (F7) and Alt_L to set the margins from the menu. * [C, D, G, I, M, P, R, S, T, U, W, Z, <, >] are file conversion commands; see 'FILETYPES VIEWED' above. The picture is converted in the number of colors you are viewing it in, thus allowing 256 <-> 16 color conversions. For PCX, TGA, and TIF files VPIC will ask if you want a 24 bit file. * [Alt F] momentarily displays filename in case you forgot. * [Alt X] prompts if you want to delete this file; Y deletes. * For marked (tagged) file viewing: [ENTER] shows next file in a continuous loop. [Alt ENTER] shows previous file in a continuous loop. [ESC] breaks the loop and returns to the menu. * [F1-F10] are adjustments for red, green, blue, contrast, and brightness which decrease/increase in pairs; ie F1 decreases red, F2 increases red. [Alt F10] restores the original palette (except after a [B] command). * If the picture is larger than the screen the Up/Dn arrows and PgUp/PgDn scroll the picture vertically on the screen. This only works if you have enough video memory and your display card will write to video memory not being displayed (Video 7 won't). VPIC doesn't scroll sideways; see 'How VPIC Operates'. Page 5 VPIC COMMAND LINE OPTIONS - The command line format for running VPIC is: vpic [[path]filespec] [/a /b /d /e /h /l /mN /0 /r /v /w /xN /yN /z /?] where: * The default path is the current drive and directory, and the default extensions are BIF, BMP, CUT, GIF, IFF, 5LBM, MAC, PIC, PCX, SCx, and TGA. * The /a option starts VPIC in Auto resolution select mode. * The /b option causes VPIC to beep after displaying a file except in slide mode or with /r. * The /d option saves files to the directory VPIC was started from; the default is the same directory you're viewing. Good for saving CDROM pics. * The /e option starts VPIC in 16 color (EGA) mode. * The /h option allows the viewing of hidden files; great for R or X rated files which you don't want to appear in the menu normally. * The /l option tells VPIC not to set the video mode. This is used to add a picture to a picture already on screen. Works best with /r /m /x /y * The /mN locks the video resolution to mode N; N is determined from the menu or the configuration file. The 256 color modes are 1-10, and the 16 color modes are 11-20. 320x200x256 is mode 1, 640x480x16 is mode 12. * The /o option tells VPIC not to check for EGA/VGA on startup and just use the configuration file info. * The /p option stops VPIC from swapping GIF background color and color 0. Good for saving to PCX files for PC Paintbrush. * The /r option immediately returns control to a calling program after displaying the picture. Calling program must reset text mode (mode co80) if required. VPIC returns an integer, and if negative means: -1 Can't find the file specified. -2 Not a valid picture file for the extension. -3 File read or write error. -4 Disk is full. -5 Not enough memory for operation. -6 An image in a GIF file is larger than the picture. -7 Operation not supported. * The /v option disables VESA detection and uses the config file info. * The /w option wait for a keypress after each image in a multi-image GIF file. Only works for multi-image GIFs. * The /xN option gives a N pixel left margin for pictures smaller than the screen horizontally; default is centered. * The /yN option gives a N pixel top margin for pictures smaller than the screen vertically; default is centered. * The /z option inhibits printing the filename of each file when showing. * The /? option gives a help screen of command line options. * The /@filename option uses the commands in file filename to do a slideshow. The default filename extension is SLD. * If filespec is a filename, the single file will be shown (the default extension is GIF for picture files). * If path\filespec is a directory, a menu of all viewable files in that directory will appear. Otherwise all files meeting the filespec will appear. For example, [vpic d:\pics\*.pcx] would give a menu of all PCX files in the PICS directory of drive D, while [vpic d:\pics] would give a menu of all viewable files in the PICS directory of D:. Options and filespec may be entered in any order. The /r option only works in single file mode, where all other work in menu or single file mode. Page 6 EXAMPLES OF VPIC COMMAND LINE OPTIONS * vpic [path\]filename[.ext] shows the single file specified. The default path is the current directory, and the default extension is GIF. * vpic [path\][filespec] will give a menu of all files in the specified path meeting filespec (may contain wildcards). The default path is the current directory, and the default filespec is any of the viewable files; just entering VPIC will give a menu of all viewable files in the current directory. If Path contains . or .., a filespec must be given (may contain wildcards). Thus ..\*.* would give a menu of all viewable files in the parent of the current directory. * vpic /a starts VPIC in auto resolution mode. * vpic /b causes VPIC to beep after a file has been fully decoded. Lets you know when the viewing options are available. Doesn't beep in slide mode or when using the /r option. * vpic /e starts VPIC in 16 color (EGA) mode; default is 256 color modes. * vpic /h allows VPIC to find and display hidden files in the menu. Great for those R or X rated files you don't want to be normally accessible. This option doesn't appear on the help screen. * vpic /r filename[.ext] shows the filename picture and then returns to DOS (or a calling application program) with the picture still on the screen. It is not necessary to change the video mode between viewing each file, but it is up to the calling program to reset text mode (mode 3) after all viewing is done. The /a, /e, /l, /m, /x, /y switches are valid with /r. * vpic /v gives a menu of the files in the current directory, but does not look for VESA info from the display card. This is useful if the VESA info is incorrect or doesn't support all the modes the card can do. * vpic /? gives a help screen for modes and command line options. Example: vpic /m3 /x0 /y0 /r file1 displays file1 in mode 3 in the upper left corner. Then, vpic /r /l file2 /x320 /y200 displays file2 starting at column 320 and row 200 leaving file 1 on the screen. Page 7 SLIDESHOWS vpic /@[path\]slidefile[.ext] will do a slide show from commands in slidefile. The default path is the current directory, and the default slidefile extension is SLD. The path applies to both the slide file and all files for viewing, but VPIC allows you to set a different path in the command file for the pictures. The commands are placed on separate lines, and consist of either: a. A filename (GIF extension assumed) and optional: 1. Display mode (number) and/or 2. Animate command (a followed by optional number with no spaces). b. A delay (viewing time) spec of the form 'd n' (space required) where n is the desired viewing time in seconds. c. A path for all the picture files in the form 'p path' (space req'd). d. The statement QUIT to end the slideshow after 1 pass. QUIT may be upper or lower case. The maximum number of files is 100. The number following the optional 'a' is the number of vertical retraces between animation steps. The default value is 8 (if no number follows the 'a'). The mode is explained below. To pause a slideshow press [SPACEBAR]; to end it press [ESC]. The default viewing time is 5 seconds if no delay spec is given. A delay spec applies to all files following in the slide file until changed. The first slide is not delayed the first time it is shown. The default viewing mode is automatic (whatever fits). VPIC understands comments preceded by a semicolon, blank or comment lines, and extra spaces. For example, the following slide file contents are understood by VPIC, but not recommended: d 20 ;Delay for file1.gif & file2.pcx is 20 seconds. file1 1 ;First file in slideshow. File1.gif using mode 1. file2.pcx ;This is a Zsoft filename with leading spaces. ;This is a comment line with leading spaces, next is a blank line. p c:\pics ;The directory for the picture files is c:\pics d 10 ;File3 is delayed 10 seconds. file3 a30 ;Show file 3, animate at 1 shift every 30 vertical retraces. d 15 ;15 second delay file4.gif. Has leading & separator spaces. file4 ;Show file4.gif for 15 seconds, then do file1.gif. The mode requires a little further explanation. In the above slide file, it says to use mode 1 with file1. Modes 1 thru 10 are the VGA (256 color) modes, and modes 11 thru 20 are EGA (16 color) modes. Most display boards only have a few of each type. The Orchid Designer has 4 VGA modes and 4 EGA modes which appear in the file menu. The VGA modes are ║ The EGA modes are 1. 320x200x256 2. 640x350x256 ║ 11. 640x350x16 12. 640x480x16 3. 640x480x256 4. 800x600x256 ║ 13. 800x600x16 14. 1024x768x16 Thus, the slide file says to show file1 in the 320x200x256 mode, and show all the others in the default modes (whatever fits). VPIC will now create a slidefile for you. In the menu you mark the files you want in your slideshow, set the delay (using Alt_D) and then press Alt_S. VPIC will prompt you for a filename, and will automatically tack on the extension '.SLD'. It saves the current delay, the current path, and the files in the order you marked them. Page 8 DETAILED COMMAND LIST - The following gives details & peculiarities of the various commands. Keyboard and Mouse Menu Mode Commands. * The [up], [down], [right], and [left] arrow keys move the cursor around the menu of files. [PgDn/PgUp] goto next/previous page. Pressing a key goes to next file starting with this character. The PgUp/PgDn area in the lower right corner allow the mouse to change pages. * Pressing the [SPACEBAR or the right mouse button] marks a file for viewing or slides, and [SPACEBAR] moves to the next file; it will also unmark a previously marked file. * Pressing [ENTER or the left mouse button] will display the marked files in the order they were marked. If no files were marked, pressing enter or the left mouse button displays the file at the cursor. * Pressing [F1] will bring up the help/menu screen; Enter or Esc will return to the menu. Clicking the left mouse button on a command activates it, and clicking the right mouse button returns to the menu. * Pressing [F2] will do a slide show of marked files until [ESC] is pressed. * Pressing [F3] will display the file size, colors, and filetype on the prompt/message line. * Pressing [F4] will toggle between 256 (VGA) and 16 color (EGA) modes. Left clicking the mouse on the board name also toggles between VGA/EGA. * Pressing [F5/F6] will decrease/increase the default resolution for file viewing. In VGA, the default resolution for 320x200 pictures is 320x200 unless 'lock' [F7] is invoked. Left clicking the mouse on a resolution sets that resolution as the default. * Pressing [Alt F6] will list all video modes VPIC thinks you have. * Pressing [F7] goes to LOCK, which forces the default resolution (above) no matter what the file size. Pressing F7 again goes to AUTO, which automatically selects a resolution which will display the whole picture. Pressing F7 again goes back to the normal default mode. You can left click the mouse on Lock, Auto, Norm, on line 25 of the menu to set that mode. * Pressing [Alt F7] allows you to lock a hi-color mode (if your video card does hi-color. * Pressing [F8] toggles the wait mode, where VPIC waits for a keypress between multiple images in a GIF file. * [F9] prompts for a new path\filespec, and displays a menu of the files in the new path meeting the filespec. * [Alt F9] gives a directory tree of the current drive in the menu window. The DOS drives are listed on the 2nd line, and may be selected with the mouse or by pressing the drive letter key. The first time a drive is selected, VPIC scans the drive for all subdirectories, and saves this info in a file called $$DRIVEx (where x is the drive letter) in the same directory where VPIC is located. Subsequent times, the drive data is retrieved from this file, and the drive is not scanned. If you added or removed directories, you should probably rescan the drive by pressing Alt_S or clicking the mouse where it says Alt S on the directory tree screen. The cursor keys work the same as in the normal file window, and a directory is selected by pressing Enter or clicking on it with the left mouse button. The directory tree is folded into 4 columns, and the indent level of a directory is shown by the lines preceding the name. The PgUp/PgDn and <- -> move the display by clicking these locations with the mouse. Page 9 * [F10] displays the current path on the prompt/message line. * [Alt C] copies tagged files (or the file at the cursor if none are marked) to specified path. * [Alt D] prompts for a new slide [F2] delay time in seconds. * [Alt L] prompts for new fixed margins (a is auto centering). * [Alt M] moves tagged files (or the file at the cursor if none are marked) to specified path. * [Alt R] prompts for a new filename to rename the file at the cursor. * [Alt S] creates a slidefile of the marked files; see Slideshows. * [Alt T] tags (marks) all files in the menu. * [Alt U] untags (unmarks) all files in the menu. * [Alt X] deletes tagged files (or the file at the cirsor if none are tagged). VPIC confirms before each delete. [Y] will delete it, [N] or ESC doesn't, and all other keys are ignored. * Pressing [ESC] ends the program and returns to DOS. * Pressing [Ctrl-Break] or [Ctrl-C] will get you directly to DOS from anywhere. All other keys are ignored. If errors are encountered, an error message appears on the third line from the bottom, and disappears when the cursor is moved. The amount of far memory available is also printed on the same line. The menu title is the search spec. Keyboard and Mouse Commands while Viewing a Picture (except in slide mode) * The up/down arrow keys will scroll the picture by one line if it is longer than the screen, provided you have sufficient display memory. The [PgUp] and [PgDn] keys will scroll by 10 lines. The Video 7 extended VGA boards do not support writing to non-displayed memory or scrolling pics larger than the screen, so this function is disabled for these boards. Straight VGA boards can't scroll in 320x200x256 mode because the picture takes up all of display memory. VPIC will not scroll sideways; see 'How VPIC Operates'. * If the picture size is <= 1/2 the screen width, pressing [2] will give a double size image (which may be scrollable) and pressing [1] will give the normal size again. For VGA, the picture will be changed only in the horizontal direction; this will unsquash some 320x400 pics so the aspect ratio is correct. * Pressing [+] will increase the resolution (320x200 to 640x480, etc). * Pressing [-] will decrease the resolution; useful if 800x600 rolls. * Pressing [/] or [?] or clicking the right mouse button gives a help/menu screen of commands available while viewing. Left clicking the mouse on the command or pressing the command key activates the command (except for F1-F10). Right clicking the mouse or pressing Enter or Esc removes the help/menu overlay. * [Alt_F] displays the current filename momentarily. * Pressing [ENTER] will return to the menu or DOS, or show next file for marked menu mode. * Pressing [Alt ENTER] will show the previous marked file (if any are marked). * Pressing [ESC] will end the display and return to the menu. * Pressing [Alt-X] will prompt you to delete the current file. If you answer [y] it will be deleted, [n] or ESC it won't, and all other keys are ignored. Page 10 NOTE: The file conversion options now work when viewing in hi-color modes for TGA, TIF, and PCX files. All the following conversion options check if the default filename is present, and prompt for a new name if it is. They create a file on the current drive and directory with the same dimensions as the file being viewed. If you screw up at the new filename prompt, hit [Ctrl-C] to escape immediately to DOS; this will usually preserve a file you don't want to write over. The safest bet is to view files in another directory using the -d command line option, since the new file is saved to the default directory, which is the drive and directory you ran VPIC from. I put VPIC in my UTIL directory, and have my PATH set to include UTIL, so I can run VPIC from any drive or directory. * Pressing [A] will 'animate' a picture by rotating the palette periodicly. This is especially effective on fractals, where large areas tend to be the same color. Pressing [SPACEBAR] will pause the palette rotation, and pressing [ENTER] will stop it and return to the command mode. Thus, by waiting for an especially nice pattern and then pressing [ENTER], the pattern can be written to a file using the file save commands. Pressing [ESC] will return to the menu. The rate of palette rotation can be increased/decreased with the up/down arrows (slow) or PgUp/PgDn (fast). * Pressing [B] will convert a color VGA picture to a 64 shade gray picture. The resulting image can be saved with the gray palette. Only works in VGA. The original palette cannot be restored with [Alt F10] after [B], but you can always redisplay the picture to see it in color again. * Pressing [C] will create a Dr. Halo CUT file with the same filename and extension CUT. A palette file (.PAL) will also be created. * Pressing [D] will create a Deluxe Paint II (Electronic Arts) file. VPIC will prompt for a normal or enhanced DP II file, and for compressed or uncompressed. * Pressing [E] will expand a Run Length Encoded (RLE) compressed Targa file. If the file is not a Targa or is already uncompressed, this key does nothing. * Pressing [F] will prompt for a new filename to overlay on the existing picture. It also prompts for x and y offsets (in pixels). The colors may not be exactly correct since the new picture uses a best match to the palette of the original picture, and some colors may be missing. This feature is handy for building composite pictures; ie, four 320x200 pics on a 640x400 screen with the screen size 'locked' using F7 or /m on the command line. Specify where you want to place the first picture on the command line when VPIC is executed using the /x and/or the /y options, or use the Alt_L command from the menu; the filename display is suppressed using the /z option on the command line. Alternately, you can have an all black picture as the first picture, then overlay the others onto it. The composite picture can then be saved in any of the file formats VPIC supports. You can also specify the /mN resolution mode from the command line to lock the video mode to the desired composite size; it can be changed once you are in the menu. Later pictures use the first pictures palette (if all are 256 color), so it's a good idea to pick the first picture with the widest range of palette colors; this gives the best rendition of the other pictures. A good way to invoke VPIC for this mode is `vpic /x0 /y0 /z /m3'. Page 11 * Pressing [G, I, M, U, <, or >] will create a GIF file on the default drive, and prompt for a new filename; the default extension is GIF. [G] is for non-interlaced, and [I] is for interlaced, [M] is for mirror image, [U] is for upside down (inverted), [<] is rotate image 90 degrees CCW, and [>] is rotate image 90 degrees CW. * Pressing [P] will create a PC Paint or Pictor file. The default extension is PIC, and for EGA it prompts for a PC Paint or Pictor file. * Pressing [R] will create a ColoRix file with the same filename and extension SCx where x is a function of the screen size. If in EGA, will prompt if you want an EGA Paint or ColoRix file. * Pressing [S] will make a TIF file with the same filename and extension TIF in whatever mode you are now using. Prompts for a 24 bit TIF. * Pressing [T] will make a Targa 16 or 24 file with the same filename and extension TGA. VPIC defaults to Targa 16, and prompts for Targa 24. * Pressing [W] will create a Microsoft Windows Bitmap file. The default extension is BMP and it prompts for a compressed or uncompressed file. Be aware that compressed BMPs are sometimes larger than uncompressed. Doesn't handle 24 bit yet. * Pressing [Z] will create a Zsoft (PC Paintbrush) file with the same filename and extension PCX. The file will be in whatever mode you are currently using (EGA or VGA). Prompts for a 24 bit PCX. * The following keys control the picture tone as follows: [F1] Decrease red content of picture. [F2] Increase red content of picture. [F3] Decrease green content of picture. [F4] Increase green content of picture. [F5] Decrease blue content of picture. [F6] Increase blue content of picture. [F7] Decrease contrast of picture (VGA only). [F8] Increase contrast of picture (VGA only). [F9] Decrease brightness of picture (VGA only). [F10] Increase brightness of picture (VGA only). [Alt-F10] Restore original palette after you thoroughly mess up the colors. Doesn't work after a [B] grey shade conversion. [V] Reverses the current palette; interesting effect especially for black & white images. After a little experimenting, a 'washed out' VGA picture can be greatly improved by using [F1-F10], and you can always start over by using [Alt-F10]. To retain a black background in a VGA picture, the brightness should be decreased when the contrast is decreased. If you have really improved the picture, you can then save it any of the supported formats. VPIC will prompt you if the file exists in the default directory, and you have the option of overwriting it or giving a new filename. This works really well with images created on the Sharp, Howtec or Targa scanners, which are sometimes 'washed out'. All other keys are ignored. Pressing [Ctrl-Break] or [Ctrl-C] will go directly to DOS. Page 12 DECODING OTHER FILE FORMATS Each picture is viewed in whatever mode you are presently using (VGA or EGA) and at the resolution you have selected. If you choose to save to another file format which differentiates between VGA and EGA modes, it will be converted using the appropriate rules. This makes EGA <-> VGA conversions possible, which is not supported by most paint programs. The decoding for other than GIF is not as fast as could be done, but the added versatility more than compensates for this. For example, EGA PCX files can be very quickly decoded to EGA, but are in the wrong format for VGA, and considerable manipulation is required to produce a VGA image. For all formats, the method of viewing is to decode to a buffer for a single line at 1 byte/pixel, then copy this line to the display in whatever mode you are using. This is a compromise for most file formats, since they are geared to EGA or VGA, and display time suffers, but it makes the code much simpler. Besides, the other formats are supported mainly to allow easy conversion to GIF, which is the preferred format for storage since it gives the smallest file size. The TGA 16-32 bit, TIF 24 bit, and PCX 24 bit files are viewind in hi- color if you have it, and color reduced to 256 colors if you don't, so the color rendition is pretty good. The Image Tools TGAPIC and Pegagsus Imaging Corp's SHOWTGA do a better job of color reduction, but only work for TGA files. If you use SHOWTGA (which converts to a Targa 256 color file), you can use VPIC to convert this to GIF. ADDED FEATURES VPIC is meant to fill a void not covered by paint programs, and to allow very convenient file viewing and conversion between file formats. It is not meant to compete with the paint programs, and in general if a paint program does something well (such as resize a picture to fill the screen or cut out a portion of the picture), VPIC will not attempt to do it. On the other hand, if you think of a feature which would enhance VPIC, please let me know, and I will consider adding it to the program. KNOWN PROBLEMS 1. The ATI VGA Wonder 1024x768x16 mode and all the S3 16 color modes use 2 pixels/byte, unlike any other VGA or EGA mode. It is supported for most viewing and conversions, but will not view or convert to EGA Paint files, ColoRIX EGA files, or Pictor EGA files, since these are on an EGA plane basis. 2. If you have a board with the Trident TVGA 8900 VGA chip, don't run MAMODE before running VPIC, or run MAMODE 64 if you were in a 128K bank mode. Some of these cards return VESA infa about hi-color modes which they can't do, so you may have to run 'vpic /v'. 3. Most boards using the S3 SuperVGA chip don't return correct VESA info, so you will have to configure with either S3.CFG or S3NEW.CFG and then do 'vpic /v' to make VPIC ignore the incorrect VESA info. 4. ATI boards in general will not enable the 800x600 modes unless you pick the right monitor in ATI's install program. I had to use a custom configuration to anable the 800x600 modes. Page 13 SUPPORT FOR OTHER SUPERVGA BOARDS I will try to support other VGA boards with extended VGA modes if the owners will write me with the details of how to set the various modes, and how to bank switch the display memory. Of course, if you also register VPIC I will give the problem more consideration. Use of a board is mandatory, since I can't tell if the new routines work unless I can try them. The bank switching Info for some of the 'not so common' VGA boards is hard to come by, and is needed if VPIC is to support extended VGA modes for these boards. A VGA board needs to bank switch for extended modes because there is only a 64K window in the PC address space for graphics memory (from A000 to AFFF), and extended modes require more than 64K of memory; 640x480x256 requires 307200 bytes of memory, or about 4.7 'banks of 64K'. Bank switching is a means of mapping the (A000 to AFFF) graphics address space into 64K chunks of actual display memory. The method of bank switching is determined by the VGA chip used on the display board, and what I need is info on how to switch banks and how to set the various modes the board supports. USEFUL TECHNIQUES Running With your Favorite Options If you like to run VPIC with a particular set of options, you can put VPIC in a directory NOT in your path, and make a batch file which IS in your path which calls VPIC with the options as follows: @echo off x:\vpicdir\vpic /options %1 %2 %3 %4 %5 %6 where x:\vpicdir is the drive and directory where VPIC resides, and the %1..%6 pass other options to VPIC. Batch Conversions (Sort of) If you run VPIC in auto mode (/a or F7) and mark the files you want to convert, the first picture is displayed when you press Enter. When the picture is on the screen, you press the desired conversion command, and when VPIC is done with the conversion, you just press Enter to view the next picture, and so on. With this technique, you can mix file types for conversion. HOW VPIC OPERATES VPIC decodes a picture file directly to screen memory on your display card. The other technique is to decode to CPU (normal) memory and then copy the picture (or a portion of it) to screen memory. Both ways have their advantages and disadvantages. Page 14 DECODING DIRECTLY TO SCREEN MEMORY (LIKE VPIC). ADVANTAGES - This method offers the best speed, since it doesn't have to go thru the intermediate step of decoding to CPU memory first. It will also always decode large pictures, even above the maximum display size. The CPU method usually doesn't have sufficient memory for large pics, like 1024x768x256, or even 800x600x256 if you have any TSR's in memory; these pics require 1 byte/pixel. The file conversion options uses the current palette data and the current data in display memory to make the new file. Thus, what you see is what you get in a new file format, in whatever mode you are viewing (256 or 16 color). DISADVANTAGES - Because the picture is decoded directly to screen memory, any picture data beyond the right edge of the screen is thrown away. For this reason, you can't scroll left and right. VPIC will continue to decode to display memory beyond the bottom of the screen until it runs out of memory, set by BANKS in the configuration file. If the card wraps memory beyond the bottom of the screen back onto the screen, like the Video 7 cards, then VPIC doesn't decode beyond the screen bottom. Thus, if your display card doesn't wrap display memory, you will be able to scroll the picture up and down. If the screen doesn't display the whole picture width, any converted file will be truncated on the right edge to the screen size. DECODING TO CPU MEMORY FIRST ADVANTAGES - If there is sufficient CPU memory to hold the whole picture (at 1 byte/pixel), a rectangular area equal to the screen size can be copied to display memory, which allows you to scroll around the picture in all directions. DISADVANTAGES - If there is not sufficient CPU memory, most of the programs will refuse to display the picture. There is also the wait while the picture is decoded to CPU memory before you get to see it. Page 15 VPIC TERMS AND CONDITIONS NOTICE - VPIC is not free software. If you paid a "public domain" vendor for this program, you paid for the copy and mailing service only, and not for the program itself. Nothing ever gets to the author of the program from such a sale. You may evaluate VPIC for 10 days, and if you find it useful, you must register your copy. There are several incentives for registering VPIC. You get free technical support (which can be quite valuable at times), you can get updates from me (with about 1M of good GIFs) for $5 ($10 foreign) to cover shipping and handling, and you allow me to stay in business and improve the program. VPIC has been evolving since 1987, and new features and/or video card support are added all the time. I have tried to make it as versatile and fast as possible, while still retaining the ease of use and intuitive operation. VPIC is copyrighted software, and all rights are reserved. VPIC may not be changed or modified in any way except by the author. VPIC is SHAREWARE, and may be freely distributed, as long as it remains in its complete form with all support, documentation, and configuration files. It may be used for a ten day free trial period. Regardless of how the copy is obtained, it is requested that all users comply with the following licensing/registration provisions if they continue to use it after the 10 day trial period: 1. $25 per copy for individual users. Users can feel free to use VPIC for anything. I need your name and address for my records, and you are entitled to: a. Use all updates at no cost (except shipping and handling; see below) provided the registration fee hasn't changed. b. Technical support either by phone (you call me) or by letter. c. If you order the latest version along with your registration (see below), you also get a printed manual. 2. Site License: $125 per 10 copies if used or distributed by you, or as part of your product. All users would be registered collectively under your name, but can fell free to use VPIC for anything. Update requests and technical support would be thru you (since I don't know the names of the individual users) and would be distributed by you to the users. 3. Quantity discounts: (Only one disk provided, you keep track of users) 10 to 99: $17.50 per copy. 100 to 1000 up: $12.50 per copy. 1000 up: $10 per copy. All registered users can feel free to use VPIC for anything. You can get technical support from me, and pass it on to your customers. Please provide me with a list of the user names and addresses, so I can honor update requests. 4. a. $1.50/copy royalty if used as part of a DEMO; a demo is not part of your product, but is a means of advertizing your product. b. $3/copy royalty if used as a utility for running your product. The maker of the demo/product must be a registered user. If a recipient of the disk uses VPIC for other purposes (not part of the demo or product) he should register. You should sign a royalty agreement with me, and make payments annually. You may estimate the yearly usage, and then correct it from year to year. You should supply to me a written statement listing the copies shipped each year. Page 16 For foreign orders, please send a check drawn on a US Bank, International or US Postal Money Order, Travelers Checks, or cash, since the banks here charge up to $60 collection fee for foreign checks. For all the above, VPIC should be distributed intact, with all documentation (DOC files), support programs (CVPIC, CONFIG, and WHICHVGA), and configuration (.CFG) files. Archived form is OK to meet this requirement, since it minimizes disk space, if you supply the un-archiving program. A user may install VPIC on more than one machine, provided he is the only user on each machine. The registration and license policy is similar to a book, which can be taken with you but used only by you. Please use the enclosed registration/order form since it allows me to keep better records and keep up with the newer VGA boards. UPGRADES FROM PREVIOUS PROGRAMS AND UPDATES You may use all updates (with the same registration fee) free once you have registered VPIC. If you are already registered for VGIF or ZS (any version) you may upgrade to VPIC for an additional $15. Upgrading from VPIC is $10. Since VPIC is updated regularly, I do not send notices, but it gets around quickly to most graphics oriented BBS's, and is available at Compuserve in Data Library 3 of the PICS forum. ORDERS FROM ME If you order a VPIC update from me, please send $5 ($10 outside the USA and Canada) for materials, postage, and handling. As a bonus I will fill the rest of the disk with good pictures. Please specify 1.2Meg 5.25" disk or 1.44M 3.5" disk, and EGA, VGA, or SuperVGA (640x480x256 etc) so I'll know what pictures to send. I have some 1024x768x256 pictures, but most are about 500K in size and eats up a sizeable portion of a disk, so if you want one of these there wont be much room for other pictures. If you want additional disks of pictures, please add $5/disk (3 disks max). I have quite a few 640x480x256 pictures (mostly by Boris Vallejo), only 1 disk full of 320x200x256 pictures and 1 disk of EGA pictures, and a few larger sizes. Data on the various file formats VPIC supports is available free if you request it with your order, but will use about 200K of disk space. Please use the enclosed registration/order form since it allows me to keep better records and keep up with the newer VGA boards.

VGIF ver 1.2 1-15-88 * Changed name to VGIF. * Slide mode now ignores the end of file mark in slide file, and any key will now end slide mode. * Added slides to menu mode if [S] pressed-shows marked files as slides until a key is pressed. VGIF ver 1.3 1-21-88 * Added better error checking to GIF file decoding. Notifies if bad GIF file. * Fixed error reporting bug in single file mode. VGIF ver 1.4 2-9-88 * Added instantaneous screen update in slide mode from menu or command (SLD) file. * Added the /r option which allows an application program to call VGIF to view a file and then regain control. VGIF ver 1.5 3-2-88 * Added [PgUp] and [PgDn] keys to scroll by 10 lines at a time. * Added a max pic height of 819 lines so EGA buffer would not overflow. * Greatly improved color reproduction for 'problem' pictures (such as FROG, ARCHIT, PUFFIN, VEGTABLE, etc). These pictures typically have more than 16 colors. Selected colors on basis of frequency of use where possible. * Fixed following bugs: 1. Line buffer would overflow into other variables if pic width was > 640 pixels, causing strange results. 2. Didn't recognize the end of image marker correctly. This would cause the palette to change when the image was done. VGIF ver 1.6 3-11-88 * Fixed a bug in handling multiple images. First noticed when viewing WHIMMI.GIF. * Use same palette for multiple images, and get best color match. * Added [L] and [S] commands while viewing a picture. These allow you to create full size paint program files. Page A2 VGIF ver 2.0 3-26-88 * Added the ability to view long GIF files ( > 819 lines) without wrapping the display. * Added the [C] and [H] (Dr. Halo) file creation option while viewing. * Added the [L] and [S] prefix to paint program file creation commands while viewing to save long pic files. * Added the Info and Help commands in menu mode. * Deleted the # requirement to specify a directory from the command line. The program now looks for a directory which meets the spec on the command line. If none is found, it assumes the spec is for a single file. * Added [F1 - F10], and [V] palette control keys while viewing a file. VGIF ver 3.0 5-2-88 * Added VGA capability, and support for Tseng extended VGA modes (640x480x256 and 800x600x256). * Determines and displays available modes for your system. VGIF ver 3.1 5-11-88 * Fixed a bug in dir/file spec from command line. Now accepts VGIF d:\dir\*.gif or VGIF d:*.gif, although the [\]*.gif is not required, since this is the default filespec. * Fixed a bug in forced EGA when doing slides, where an interlaced pic displayed at double size would have a 'venetian blind' effect. * Changed so pics larger than 320x200 are shown in 640x480 VGA; can get 800x600 by pressing + key. * The EGA mode on the Orchid VGA card appears squashed vertically. This is normal, and cannot be corrected without reprogramming the parameters for mode 16, which would change the vertical retrace frequency and probably cause your monitor to roll. VGIF ver 3.2 5-26-88 * Added 500 file menu, and assy language text screen updating; now super fast. * Fixed a bug which caused the Vega VGA card to hang up. VGIF ver 3.3 6-9-88 * Added user spec of video mode for non-Orchid VGA boards. * Added GIF and Pictor save of current screen for VGA/EGA pics. * Added prompts to screen for conversion to other formats. * Removed conversion starting at first visible row-now does whole pic. VGIF ver 3.4 6-23-88 * Fixed a bug in the GIF save routine. * Added color, contrast, and brightness adjustment in VGA. * Fixed a bug in menu mode for marked files. * Added /n command line option to stay in 640x480x256 for VGA pics. VGIF ver 3.5 7-14-88 * Fixed some misc minor bugs. * Added increase/decrease resolution command while viewing 16 color VGA pics (using the /e option). * Added slide mode for VGA. * Added lock mode option to start pics from the menu in a desired mode. VGIF ver 3.6 8-8-88 * Fixed some bugs. * Fixed EGA slide show. Page A3 VGIF ver 3.6A 9-10-88 * Fixed 1024x768x16 mode. VGIF ver 4.0 10-20-89 * This was a beta test version which got out. It had lots of bugs, which were fixed in VPIC. HISTORY OF VPIC VPIC ver 1.0 & 1.1 12-27-88 * Beta test versions. VPIC ver 1.2 12-27-88 * Added configuration option for various display boards. * Added VGA file conversion for all previous Paint programs supported. * Added Deluxe Paint 2 conversion. * Added Targa 16 file conversion. * Added EGA/VGA toggle from menu. * Added default resolution select, and Mode Lock key from menu. * Added WAIT option to pause between images of multi-image files. * Added MAC, PCX, & Colorix file viewing capability. Others will be added in later versions. * Added 'animate' while viewing. * Fixed VGA 16 color palette. VPIC ver 1.2A 1-4-89 * Fixed MAC -> GIF conversion * Fixed CVPIC for ^Z as EOF char. * Fixed 16 color palette for other file formats if VGA 16 colors. VPIC ver 1.3 2-2-89 * Fixed cursor in menu. * Fixed 'lock up' if GIF header size wrong (640x350 labeled 350x640). * Now pauses pic if file error and waits for key press-can see partial pics in bad files this way. * Shows GIFs with MAC headers (1st 128 bytes are not GIF standard); if F3 (info) pressed shows if file has a MAC header. * Fixed so views and saves new Zsoft VGA PCX files which include palette at end of file. Still doesn't load PAL files. * Fixed Zsoft file displays and saves. * Added Wait toggle (F8) which pauses between images in multi-image GIFs, and allows conversion to other filetypes. * Made MACs black on bright white instead of gray. VPIC ver 1.4 3-15-89 * Added printout of filename while decoding except in slide mode. * Added help while viewing a picture; press [?] or [/]. * Added delete a file option [X] (with query) while viewing. * Added hit [ESC] while decoding to abort picture. VPIC ver 1.5 3-23-89 * Fixed bug in 'Escape while decoding' which would hang system. * Fixed EGA x2 display for interlaced files. * Fixed problem with saving a pic after scrolling. * Fixed palette in animate, so save will use current palette. * Fixed problem with bad files in slide mode that would hang computer. * Fixed error display in /@ slide mode and single file mode.

VPIC ver 4.7 never released Someone tried to add the Dark Avenger virus to VPIC in the Boston area. You can't change a single byte in VPIC or it will refuse to run, since it does a checksum on itself. They used a batch file or some other sneaky thing, and had the virus assemble and execute after exiting VPIC. It was not detected by Central Point Virus Scan, since it wasn't an EXE or COM file, but was detected by someone there who sent me a letter with the name and phone number of the person who uploaded it. The FBI is currently investigating it.

When you register or upgrade from a version prior to 6.0, and get the latest version from me, you also get a printed manual. VPIC ver 6.0a 1-17-93 * Added super 16 color palette selection for viewing in 16 colors. Pictures are not dithered, but look better than some dithered pics. VPIC ver 6.0b 1-30-93 * Added VESA ver 1.2 checking, so it recognizes hi-color modes. * Added Alt M to menu to tell you what modes are currently defined. * Added Alt C to menu to set the hi-color mode (8, 15, 16, or 24 bit). * Fixed Alt S (from the keyboard) to rescan a drive after Alt F9. * Fixed 'Abort, Retry, Fail' problem when you have additional floppy drives above drive C.

Alt_C now copies all tagged files to a different disk/directory, and Alt_M moves them to a different disk/directory. Alt_X now deletes all tagged files, but prompts you for each one. If not files are tagged, the single file at the cursor is copied, moved, or deleted. VPIC ver 6.1 8-10-93 * Fixed a minor bug in block delete. * Finally added TIFF view/convert support, including LZW compressed TIFs. * Added color reduction to 16 or 256 colors. Whew! * Added Alt_S to menu to make a slidefile for the current marked files. * Added conversion support for hi-color viewing, including mouse, menus and prompts. If you want to save a color reduced version of a hi-color picture, view it in 16 or 256 colors and then do the conversion. * Added Slow Scan TV HRZ (18 bit/pixel) file format for viewing only.
