- What is PicView?
-
- PicView is an picture viewer that offers features not found in
- other viewers. This is not the end all program (yet). Other viewers
- do offers some features that PicView does not, such as graphic
- conversion. Some of the 'deficiencies' of PicView will be added to
- later releases.
-
- Currently PicView will read and display GIF, Colorix and MAC
- formats. We are currently working on implementing more formats,
- notably compressed RIX files, PCX and Deluxe Paint LBM files. Other
- formats are being looked into, and will be implemented as we accrue
- information on them.
-
-
-
-
-
- What makes PicView different than these other viewers?
-
- Ahh glad you asked that question (you did ask that, didn't
- you?) Well, for starters, our biggest pride with this product is the
- superb ADJUSTABLE palette animation. A picture can be animated
- through the entire palette, a portion of the palette, and through a
- range of colors in the palette. The effects of the animation must be
- seen to be truly appreciated.
-
-
- It also sports a very easy to use window interface that if not
- for the complex animation capabilities, would preclude the need for
- docs at all. It uses very easy pop-down windows for all parameter
- setting and selection very similar to the environments used in
- Borland's Language's (Guess will have to look out for the look and
- feel police.)
-
-
- PicView supports ATI, Tseng, Trident, Video7, Paradise, C&T,
- Everex, Cirrus, and Ahead A & B chipsets. It will auto detect if
- these adapters are installed, and adjust the mode selections (screen
- size) accordingly. Also, for you True Blue users, a special
- 360x480x256 mode is implemented for you to get almost SVGA perfor-
- mance out of your motherboard VGA. This will also work on all
- register compatible VGA cards. PicView currently does not (and most
- likely won't ever) support standards less then VGA. There are several
- viewers on the market that support EGA and below, so it seemed rather
- pointless since PicView's animation abilities are best done on VGA.

- possible settings.
-
- DEMO.BAT Batch file which creates and demonstrates
- PicView's Slideshow abilities.
-
-
- In the Works
- Some of the features that PicView will be incorporating in
- future releases are:
- A script language for slideshow presentations.
- Support for more file formats i.e. PCX, LBM, etc.
- Mode lockout.
-
-
-
- Getting Started with PicView
-
-
- You can start PicView by either typing PV at the DOS prompt to
- get into menu mode, or you can specify a filename or listfile from
- the command line to immediately display a file or slideshow.
-
- When starting PicView in menu mode, a credit screen will pop
- up. By default, PicView starts in 50 line mode. If you prefer, you
- can start it with the command line option -25 or /25 to have it
- default to 25 line mode. Strike a key, and you will be in the file
- selection window. From the main menu, you have 4 choices, detailed
- here.
-
- Note: If you get tired of viewing the laserline, you can delete the
- data.pix file and it will no longer display.

- Info
-
- Pops up the opening credit screen. (In case you get bored, or
- want to know who wrote this contraption.)
-
-
- File
-
- Pops up a sub menu used for file selection.
-
-
-
- Options
-
- Brings up a sub menu to select PicView's options.
-
-
- Exit
-
- Exits the program. (That's a hard one to figure out, eh?)
-
-
- Submenus have a varying number of selections that either pop up an
- additional submenu, prompt you for data, or display a selected file.
- Submenu options will be detailed here.
-
-
- File
-
- Select File(s)
-
- This selection pops up a file selection window which allows
- you to select the file to be viewed. The window sports a scroll
- bar to give you an indication of how far along you are in the
- list of files. There is a real file limit of 16,384 files that
- can be read into the directory (assuming you have a 640k
- machine). You can use first character selection to speed you
- through your files. Hitting 'T' once will take you to the first
- file beginning with T. Hitting it again will take you to the
- next and so on. The list can be scrolled beyond the end or
- beginning if scrolling in reverse. When you find the file you
- want to display, Hit the 'ENTER' key and it will be displayed.
- If viewing a MAC file, Home, End, PgUp, PgDn, up & down arrow
- keys will scroll the picture. After the file has been
- displayed, strike any key to return to the file selection
- window. When you return, you will have the last file displayed
- still highlighted.
-
-
- File Type
-
- This selection will pop up a little window that allows you
- to select which type of file you wish to have in the selection
- window above. Currently your choices are, GIF, RIX, and MAC.

- Options
-
- Screen
-
- This will pop up a submenu allowing you to select which
- screen mode you want the picture displayed in. Depending on
- your video adapter, you may not be able to select all of the
- choices. The Auto select option will let the program select the
- best video mode for the picture to fit in.
-
- Note: You can hot-key into this window with the F3 key.
-
-
- Animate
-
- This will pop up a window prompting you for data to control
- the animation facilities of PicView. The first data item you
- are prompted for is whether or not you want animation on. If
- you select 'N', the window is dropped, and you are returned to
- the next level up menu. If you select 'Y', you are then
- prompted for the direction, palette, starting and ending
- registers, and depending on the palette selected, starting and
- ending color data. More detail will be covered on this topic
- later.
-
- Note: You can hot-key into this window with the F4 key.
-
- Exit
-
- This selection returns you to DOS. Optionally, you can hit the
- escape key at any top level menu to return to dos as well.
-
-
- Hot Keys
-
- Hot key access to menus are as follows:
-
- F3 - Pops up screen size selection window.
- F4 - Pops up animate window.
- F5 - Brings up PalView for selected file.
- F6 - Displays the dimensions of the highlighted file.
- Alt D - Deletes the highlighted file from your drive.
-
- The 'A' key while viewing a picture will cause animate to start
- using the defaults, or the selections made when you last turned
- animate on.
-
-
- To start PicView with a filename, simply type PV filename.
- Extensions are optional, but if omitted, GIF is assumed. Filename can
- consist of a filename and optional path of up to 80 characters.
- PicView will then display the file and wait for a keypress (or an 'A'
- key to begin animating the pic). If you also specify a /r or -r on
- the command line, PicView will display the image and exit leaving the
- graphics mode intact. This is useful for calling PicView from other
- programs to display a graphic image. When started with this option,
- PicView will not animate.

-
-
- To start PicView with a listfile, simply type PV @listfile.
- PicView will then read filenames from the listfile and display them in
- a round robin fashion, in a continuous cycle (or until aborted with
- the esc key). Filenames in the listfile with no extension are assumed
- to be GIF. A list file can be generated as simply as typing, DIR >
- LISTFILE. No editing of the dir output is neccesary as anything not
- valid is ignored. The next release of PicView will have a more robust
- script language to control delays and animation.
-
-
- What is PalView?
-
- PalView is a handy utility that will display on screen the
- contents of all you palette registers. For PalView to work, you
- must have the file selection window open with a file
- highlighted. Then, hit the F5 key and your screen will change
- to display the palette. If animate is turned on, it will
- animate the palette display. Any key will return you to the
- file selection window. (This is useful for determining the
- ranges of any smooth palette blends you may see in a picture.)
-
-
- OK, Let me go into some details on the animation options, as
- some of it can be a bit confusing.
-
-
- After selecting 'Y' to the animate prompt, your next prompt will
- be for the direction to animate. View both, as the different
- directions can have an entirely different effect. The direction is
- relative, and can/will be different from file to file (dependent on
- how the palette registers were laid out at the time the file was
- created).
-
-
- The next prompt after selecting the direction, will be for you
- to select the palette. You have 3 choices here, a random palette,
- the default palette, and a plasma palette (based loosely on the demo
- plasma). Use experimentation here, as different images work better
- with different palette selections. The random palette will look
- pretty good for just about any image (note: images with smooth
- palette ranges animate the best). If the default palette is laid out
- well without many 'holes', this one works well too. Although, I have
- viewed some images that DO have 'holes' which enhanced the animation
- effect. The plasma palette is based on a smooth transition of red,
- green and blue and restricts the animation to the first 180 or so
- registers (again, based loosely on the images created by the demo
- plasma).
-
-
- If you select the Default palette, a window will pop up
- prompting your for starting and ending color. This will be discussed
- in the next section as it is related to registers, but only applies to
- the default palette.
-

-
-
-
-
- OK, I trust you've kept up with me so far. Here's where it can
- get confusing. Your next prompt is for the starting and ending
- register. If you've selected either the Random or Plasma palette,
- this will tell the program which color register to start the animation
- at, and which to stop it at. This gives you the ability to animate a
- portion of the image, instead of the entire image. This works VERY
- well for images that use a smooth palette range in a portion of the
- picture.
-
-
- Now, if you've selected the Default palette, your start and end
- registers take on additional meaning in conjunction with the start and
- end color window that popped up after you selected DEFAULT. To give
- you a better understanding, picture your image like this. Every pixel
- gets its color from one of 256 palette registers. The start and end
- registers are exactly that, PHYSICAL registers in the machine. The
- start and end colors are the color data contained in those registers.
- When you select your start and end register, you are selecting the
- physical registers that are scrolled. When you select the start and
- end color, you are selecting the range of color data that you want
- scrolled through those registers. If you select a color range smaller
- than the palette range, the number of colors you selected will
- determine the number of registers scrolled. However, if you select a
- smaller range of registers than colors, then the registers will scroll
- through the entire range of colors you selected
-
-
-
- OK, are you thoroughly confused? I thought so, but experiment a
- little after reading the docs (preferably with the images that came
- with the PicView file since they have smooth palette ranges, it makes
- it clear sooner what exactly is going on).
-
-
-
- Command Line Option Summary
-
- -25 or /25 Start menu mode in 25 line mode.
- filespec Bypass menus and display single file.
- /r When single file specified, exit PV with graphics
- intact.
- @listfile Display filenames in list file continuously.
-
-
- Hot keys
-
- F3 - Pops up screen size selection window.
- F4 - Pops up animate window.
- F5 - Brings up PalView for selected file.
- F6 - Displays the dimensions of the highlighted file.
- Alt D - Deletes the highlighted file from your drive.
-
- The 'A' key while viewing a picture will cause animate to start
- using the defaults, or the last selections made when you last
- turned animate on.
