OpalPaint History V1.0 Initial release V1.01 Fixed mutual exclusion of the B3 gadget on the main menu (no longer stays on). Paper types no longer turn themselves back on after the smooth paper gadget has been pressed. Overscan vertical page size now correct. Fixed a bug which caused the spare page menu to crash occasionally when more than 9 pages were open. V1.1 7/11/92 Added ARexx support, 156 commands. Added Alpha channel edit mode. Added Backgound Fixing and Freeing. The backgound can be fixed by pressing Amiga-b and freed using Amiga-B. Fixed 'Scale View' keyboard equivalent in feedback area on main menu. Now loads HAM8 images. (All Opalvision software now supports HAM8). Holding down the ALT key while the extras menu is displayed now gives the HSV range of all pixels the mouse pointer has gone over. To determine the HSV tolerance required for an area of the screen, move the pointer into the desired area, depress and hold the ALT key then move the pointer around in as much of the desired area as possible. The final values of H,S and V can then be used as fill and brush cut tolerances. Increased speed of the Zap tool 200%-300%. Palette mapped Zap's have been sped up dramatically. Added Real time previews for palette mapped drawing modes (Posterise, Gamma, Contrast, Brilliance). Most menus are now draggable. To drag a menu you must click the mouse button within approx. 1cm of the top of the menu. Some menus containing 24bit graphics cannot be dragged. Added ADPro Operator interface. After the gradient fill menu has been entered via the 'Set Fill Type' gadget in the flood fill menu, it no longers returns back to the Flood Fill menu. Removed the occasional screen flash that occured when a flood fill completed. Improved the pressure sensitivity to give better control over the low pressure range when using a pressure sensitive graphics tablet. Changed the 'Cancel' gadget to 'No' in the scale image requester. Fixed a bug which caused circular brushes to turn into rectangular brushes when an artist tool was removed. Brushes can now be picked up off a solid background colour by using the right mouse button while cutting the brush. OpalPaint will automatically determine the background colour by analysing the perimeter where the brush is being cut, and replace the cut out area with this colour. Changed compilers from Manx v5 to SAS v6.0. Unfortunately it was not possible to maintable compatibility will v1.0 drawmodes and artist tools. Added 8 editable Gradients. (Instead of just 1). V1.2 15/12/92 Added FindPixel, FindNextPixel, DisplayStatus and DisplayPercent ARexx commands. Added overscan painting. Now loads brush ALFA chunks correctly. Turns off Mode Promotion (enabled in Input Control Prefs) while OpalPaint is running under AmigaDOS 3.0. FileRequester now displays correctly when called from within an Artist Tool or Paper Type module. Added ToolTypes and command line parameters. PaletteMapped drawing modes now work correctly when a paper type is active. RubThrough now works correctly with Zap. Added Amiga-d key for drawmodes options requesters (internal to modes) Changed font size gadgets in font requester. Now searches OpalPaint:Rexx first, then Rexx: for ARexx scripts. Placing OpalPaint scripts in OpalPaint:Rexx is suggested. Sending an ARexx command to 'OpalPaint_Rexx' will now de-iconise Opalpaint. Added 'N' key to center the view of the current page horizontally. (as much as possible) V1.3 Fixed Alpha undo clipping when image is larger than the screen. Rotate ARexx command now works correctly. Alpha transparency mode did not work correctly with some drawing modes, now fixed. Two internal palettes (paint pots) are now stored, one for alpha paint mode and a second for paint and stencil modes. Alpha transparency is now a seperate transparency mode. The TransType ARexx command has been modified to support this. The format of the command is now: TransType Type [Trans1 [Trans2 Trans3]] Where 'Type' can be STANDARD,RGB,HSV or ALPHA. V1.4 06/01/93 Zap now allocates an undo buffer if possible. If there is not enough memory, a warning that the operation is not undoable message is given. No longer calculates brush outline twice when loading 32bit brushes (cutouts). Added 'Invert' gadget to 'Alpha Paint Options' requester. Added 'N' key to center page horizontally. Added MarqueeFill, KillMarquee, MagicWand and MagicWandCut Arexx commands. Added 'OverscanPaint' ToolType. To disable overscan painting, add the tooltype 'OverscanPaint=NO'. Alpha Transparency mode is now exclusive to Global, RGB & HSV, and has its own 'strength' slider. Added Balance drawing mode. V1.5 14/01/93 Again key 'a' now works correctly with marquees. Hiding and exposing the menu bar while a marquee is active now works correctly. Added Amiga-T key for Pressure control options. Fixed problem in JPEG loader which caused it to very occasionally corrupt images on loading. Removed double mouse button option to hide menu bar. This was very difficult to use and caused problems when using a calcomp tablet with two buttons. When executed as an ADPro operator, now returns to ADPro's main screen instead of the WorkBench if the WorkBench screen was closed down by OpalPaint. Added Brush virtual memory. Pressure interface rewritten, now supports AmigaDOS 3.0 ExtIntuiMessages to recieve pressure data, as well as the TriMedia/Commodore equivalent for AmigaDOS 2.0. v1.6 12/02/93 Brushing routines rewritten, all brushes are now dynamically scalable through tablet pressure. If menu is hidden, mouse pointer now shows percentage done. MagicWand can now be aborted while searching. Amiga-s now does a save (no requesters) and Amiga-S is Save As. AskInt ARexx command now takes a default value. Format is: AskInt MinInt MaxInt Default HailText Gradients can now be saved seperately. Added 'AllowSaves' Rexx command to disable saving. Usage: AllowSaves [Enable|Disable] Added -r Cli paramater to allow an ARexx command to be executed on startup. Zap now works with gradients and brush fill mode. Zaping and image with the linear free option will bring up a requester to allow the gradient angle to be entered. Now handles NTSC and PAL screen modes a lot better under AmigaDOS 2.0 and greater. OpalPaint can be switched between PAL and NTSC using the screenmodes preferences editor. Added AmigaGuide interface for context sensitive online help. Zapping with a colour mapped drawing mode no longer ignores transparency, paper types, stencils and gradients. Added the ability to save and load Stencil,Alpha and Image data seperately. Added loader saver interface (LSI) for external fileformat conversion modules. v1.7 14/02/93 Handle placement and brushsize now correct when a artisttool is resized by hand (i.e. 'Z' key) No longer crashes when 'view full page' is used in alpha paint mode. No longer crashes when swapping between pages (or loading into a page) when in alpha paint mode. Alpha paint slider in palette requester is now in the correct position after going in and out of overscan mode. Reversed pressure sensitivity on chalk and pencils. Added 'ABOUT' tooltype. To stop the about requester appearing, add the tooltype ABOUT=FALSE or ABOUT=NO to the OpalPaint icon. Increased the number of ARexx scripts from 10 to 30 by using the qualifiers 'Amiga', 'Alt' and 'Ctrl' (with F1 to F10). Now gives a warning message if running on a 68040 and the 68040 FPU emulation library is not installed (68040.library) or if running on a 68020/30 without a 68881/2 installed . If you get this message then expect some crashes. NOTE: v36 of the 68040.library did not inform the system correctly of its presence, if you get this message and the library is installed, try v37. v1.8 22/02/93 Help Screen height is now correct in NTSC. AddNoise and LumaNoise use a different random number generator to remove patterns caused by a not so random sequence. OK Gadget in modes menu no longer becomes selected when the magic wand is used. Areas can now be removed from the marquee using the magic wand. If the 'Amiga' key is held down while performing a magic wand fill using the right mouse button, the selected area will be removed from the Marquee. Undo paint mode no longer stays on when the magic wand is activated using the right mouse button. Brush feather is now officially added (previous versions had it in a primitive form which I was using for testing). To feather a brush, type Amiga-F (thats capital 'F'), and it will ask your for a radius, the radius will determine how wide the feathered transparent edge will be. Removed a bug which caused the menu bar to become trashed when drawing. Rectangular brushes are now outlined correctly. Fixed stencil display updating problems when jumping in and out of magnify mode. Now loads JPEG JFIF images with restart intervals correctly. (such as those generated by PhotoShop). When loading and saving image components, the file requester now tells you what components are being saved and what fileformat is being used. v1.9 01/03/93 Added Feather, outline and trim gadgets to Brush manipulation menu. Added fix and free background gadgets to the spare page menu. Added 'AskProp' ARexx command, the syntax is: AskProp Min Max Default Message This command brings up a requester containing an OK and cancel gadgets and a proportional (slider) gadget. 'Min' and 'Max' define the range of the slide, 'Default' is the starting position for the knob, and 'Message' will be displayed in the requester. Message can contain \n sequences to start new lines. Added Amiga-j key sequence, this clones the current page and jumps to that page. The RestoreSetUp ARexx command now returns and error if the setup was not saved. The FileFormat requester now always comes up when saving files, with the exception of a file update using the amiga-s seqeunce. This was added because the old method was found to be dangerous in that if you saved the stencil seperately for example, then forgot to change the save component options back again, you would continue to save the stencil only, and not the image data as well. V2.0 03/03/93 Fixed help text for brush outline and trim gadgets. Removed occasional screen flash when updating the framebuffer. No longer looses 300 bytes when exiting. Gadget positions are now correct when jumping in or out of overscan mode and in brush cut mode. Removed a bug which caused the 24bit display to be left on occassionaly during access to the online help. v2.1 29/03/93 No longer crashes when loading an IFF stencil plane as an Alpha channel (ignores the load). No longer gives a 'File Corrupt' message when loading an IFF file that contains an alpha channel only. Overlap clipping on circular brushes now works correctly in sketch (dotted) mode. Now loads Grey scale JPEG files. No longer trashes the workbench display when iconising from an interlaced image to a DblPAL,DblNTSC or other high scan rate workbench screen mode. Zapping with alpha transparency now works correctly when image is larger than the screen. Now loads IFF images without a CAMG chunk and greater than 640 pixels wide as overscan. v2.2 26/07/93 Cleaned up the Loader,Saver interface. Fixed some minor bugs in the command interface. Added 'DisplayMode' tooltype to override the PAL/NTSC screenmode detection. To force opalpaint to run in one mode use either: DisplayMode=PAL or DisplayMode=NTSC Likewise, added cli equivalents, '-n' to force NTSC and '-l' to force PAL mode. No longer crashes if the screenmode driver (i.e. PAL or NTSC) is not available to open the intuiton screen. No longer crashes if a page with a papertype attached is resized more than once. No longer opens on output window on the workbench when ARexx macros are invoked, error results from ARexx are parsed by OpalPaint and displayed directly on the OpalPaint screen. This avoids reopening the Workbench if it was closed down, and avoids the problem of the workbench screen poping to the front if it was closed. Added background removal. This is useful for rotoscoping, first fix the background of the image with Amiga-b, then paint over the top of the original image. Hitting Amiga-k will subtract the fixed background from the current image leaving only the areas painted after the background was fixed. Now switches to overscan when loading an image which is overscan size vertically but not horizontally. No longer breaks up the image in hires when picking a colour and attempting to scroll the display. Removed screen flash when scrolling and picking a colour. Added Switcher interface, iconising OpalPaint will now return to the switcher. The switcher can access the pages directly from OpalPaint's memory. The 'Click here to Continue' window when OpalPaint is iconised now adjusts to suit the workbench screen font. v2.3 AskProp ARexx command now sets the default prop value correctly when the minimum value of the range is non-zero. Also removed round off error when the prop range is large (i.e. >1000). Workbench gadget (in extras menu) is now the 'Switcher' gadget if OpalPaint was executed from the switcher. The RGB & HSV sliders in the palette requester are now updated when moving other sliders or using the colour picker. This was too slow under 1.3, but the speed should be fine on most machines running 2.0 or greater. Made RGB&HSV prop gadgets larger in palette requester. Removed a bug in the palette requester which caused it to behave erratically if the container area of any of the slider gadgets was clicked too rapidly. Added '-u' cli parameter which forces OpalPaint to always operate in underscan mode. This is equivalent to the 'OverscanPaint=NO' tooltype parameter. Now disables ECS border blanking. The Amiga graphics are now aligned correctly with 24bit graphics when 'hack' border blanking utilities are in operation. Now operates in 2x bandwidth mode on an Amiga 4000, this increases drawing speed substantially. The first mouse button click to activate the OpalPaint window (if the window has been deactivated by for instance selecting a window on the workbench) is now ignored, i.e. will not draw anything. The 'p' keystroke now exits the palette requester. Added new ARexx commands 'LoadComponents' and 'SaveComponents' to set the image components which are loaded and saved (as set in the load/save options requester). Both these commands accept the keywords 'Image','Stencil' and 'Alpha'. e.g. to turn on the loading of all image components use the command: LoadComponents Image Stencil Alpha Scaling an image to fit the page size, now uses the Smooth1 method rather than Blocky. This will only effect image scaling when the page is increased in size. Modified ADPro Operator interface to allow OpalPaint to remain resident in memory when returning back to ADPro. This reduces the time required to swap between ADPro and OpalPaint. AskString ARexx command now accepts a default string. The calling format is now: AskString Heading Default The 2 strings can contain spaces but need to be enclosed in quotes, ARexx strips off the first level of quotes, so the following trick has to be used to sucessfully quote the string: e.g. AskString "'This is the heading' 'This is the default string'" To Keep compatibility with the old AskString, if a string is found that is not quoted and contains spaces, the entire string is treated as the heading for the requester. Added preferences option to raise the menu bar when in overscan mode. This makes it easier to work in overscan mode with monitors that cannot display the full overscan height. Fixed a bug in the RubMode ARexx command. Added KeyFile to allow all key board commands to be user definable. ARexx Command 'Key' now accepts Keyword command (as defined in the keyfile) as a parameter. This is the prefered method to use as people may redefine the key commands making your ARexx script incompatible. e.g. Key Amiga q - Old Format (still accepted) Key Quit - New format. Works regardless of keyfile. Added pen flicks for hiding/exposing the tool bar and the palette requester. Added Pantograph texture mode. (Alt p, Alt P) Added Clone texture mode. (Alt c, Alt C) 'TextureType' ARexx command also accepts 'Pantograph' and 'Clone' as a parameter. Added 'Pantograph' ARexx command: Pantograph Enable x y Added 'Clone' ARexx command: Clone Enable x y Added GIF Loader. Added VPB Loader/Saver. This format is CCIR 601 (4:2:2) uncompressed, as used by Quantels Picture Port interface. Zapping gradients into the alpha channel now works correctly. Added the ability to Zap brushes (Amiga Z) Added frame grabbing menu for source selection etc. Installation of the loader saver modules is now automatic, there is no need for the InstallLSI program anymore. Disables brush outlines while an ARexx script is running, this will increase the speed of most scripts. Now turns off the 24 bit display when the OpalPaint screen is not in front. This enables OpalPaint to multitask a little beter when swapping screens using Amiga-m. ARexx commands ActiveBrush, ActiveNozzle and ActiveGrad now return the current settings (i.e Current Brush, Nozzle or Gradient setting). Added ARexx command "ImageToAlpha". This command copies the current image into it's own alpha channel. Added ARexx command "AlphaPattern". This command allows the alpha background pattern to to be set (see the Alpha Paint Options menu). The allowable pattern values are 1 to 6 or GreyScale or GrayScale. e.g. AlphaPattern 4 AlphaPattern GreyScale Added ARexx command "InvertAlpha". This command inverts the contents of the alpha channel. Added ARexx command "DeleteAlpha". This command deletes the current alpha channel. Added ARexx command "AddAlpha". This command adds an alpha channel to the current image if it doesn't exist. The CopyPage ARexx command now accepts an additional 2 parameters for an x and y offset. i.e. AddPage [Src Dest [x y]] If the x and y offset are specified, the source image will be shifted by that offset when it is copied into the destination page. The size of the destination page will not be modified. If the offsets are not specified, the command will act as before and copy the current page into the destination page, resizing the destination page if its not the same as the source.
