Metagraphics MetaWINDOW Revision History
Versions 4.4A through 5.0B

Fixed in Version 5.0B

• Fixed bugs with CopyBlit from S3 to memory.
• Fixed bugs with S3 cursor tracking when cursor partially off bitmap.
• Fixed bugs with S3 GetPixel and FloodFill not getting correct pixel value.
• Added S3 1280x1024 256 mode.
• Added (undocumented) InitGraphics() codes for S3s that use VESA mode set (just add 1).
• Fixed AlignPattern() GP fault under PowerPack DPMI32.
• Fixed DestroyBitmap() bug for 286 PM.
• Fixed CloseBitmap() bug under 386 PM when InitBitmap() failed.
• Fixed bug concerning going to text mode then comming back for banked devices.

Fixed in Version 5.0A

• ResrcQuery() was ignoring argCount and just doing 1 file.
• Made Watcom with Rational or Pharlap preserve EBX on calls.
• Made TNT generic lib (Borland-Ms-watcom) preserve EBX.
• Increased page lock size for parts of the cursor tracking code.
• Put support in GetPixel() and ReadImage() for S3 Vision64 chips.
• Added SetBitmap( GrafPgAll ) support for S3 modes.
• Added page flipping support for S3.
• Added WaitRetrace() support for S3 modes.
• SetFont(NULL) no longer calls QueryError() to post a bad font message.
• ResrcQuery would blow chunks if givin a NULL pointer.
• Fixed bug with CreateBitmap( cDISK ) and Power Pack.
• Fixed bug with round pen and local coordinates drawing line in wrong coordinates.
• Fixed bug with SetBitmap( GrafPgAll..) and VESA modes in 32 bit.

Fixed in Version 4.4C

• 1280x1024 256 color VESA mode was being stubbed out with the 16 bit code in libs that do not have 16 bit drivers.
• Visual C 32 and Borland C with Phar Lap TNT were crashing on cursor tracking with 256 color drivers.
• Removed save/restore of es in DestroyBitmap().
• Fixed bank manager for Paradise/Western digital 1024x768 16 color
• Fixed bug with hicolor driver and images that span 64K in real or 16-bit protected-mode (would crash if bank span and seg span).
• RectRegion()/SetRegion() were not maintaining ds for alloc calls. Bug introduced in 4.4A.
• Made VESA page flip try to flip even if VESA says it only has 1 page due to buggy VESA driver
• Fixed bug with synth text facings TextFace() for borland power pack 386
• Fixed bug with Tseng 4000 800x600 16 color crashing on init. Bug introduced in 4.4A

Fixed in Version 4.4B

• Changed name of code segment on watcom builds to _TEXT.

Fixed in version 4.4A

• FrameOval() with a wide pen crashed when oval so small the hole in the middle closed down (only in some coordinate cases).
• FrameOval() with PenDash() and very small oval would crash with divide by zero.
• Proportional text with transparent replace on 8 bit per pixel 386 dropped out parts of characters.
• RectRegion() and SetRegion() did not convert coords to global.
• Pascal TPUs had SetBitmap() with only one arg.
• EmptyRect() would report empty only if both x and y were null.
• Phar Lap 286 would GP fault if the driver couldn't be loaded due to an out of memory situation.
• Added support for 8 bit DACs via mapFlag mfDac8
• Added support for joystick mouse
• Added 24 bit support to XlateImage, including 8 bit/3 plane PCX file format, as well as 16->24 and 24->16 color xlates.
• Fixed bug in multiplane driver WriteImage() when using region clip.
• StringWidth16() was interpreting the string as chars not ints.
• CharWidth16() was declared as taking an int, should have said word.
• MapPoly() in Pascal was not using correct parameters on the stack
• GrafPool() called after InitGraphics() was not using the right segment when calling free() in 16 bit libraries.
• ATI Graphics Ultra Pro SetDisplay() for 1280x1024 was not setting the hardware clipping. If was ever set to 1024, then anything beyond 1024 would be clipped in 1280 mode.
• SetBitmap() now 'remembers' what page the grafMap is set to and can tolerate being called twice in a row for the same page, as well as can handle up to 8 pages (320x200).
• SetDisplay() now determines if the grafMap is already in graphics mode and if so simply flips the page with an OUT instruction.
• Put (back) in filled rect support for stroked fonts
• Increased interrupt stack to 1024 bytes for real mode due to the extra overhead when using VESA drivers.
• Added new GrafPgAll feature to SetBitmap().
• Added Query support for ATI Wonder.
• Added new function WaitRetrace()
• Added new functions CreateBitmap(), DestroyBitmap().
• TextFace() synthisized facings and TextPath() with pathUp or pathDown would draw all characters to the same spot (displaying only the last one).
• Added 5:6:5 hicolor format flags to grafMaps and images.
• Added 5:6:5 hicolor format support to XlateImage().
• Added support for Phar Lap TNT NtStyle exes using dlls.
• Added support for the Borland 386 dos extender.
• Added FindClosestRGB()
• Added BitmapToRegion()
• Added DestroyRegion()
• Removed query support for Tseng 4000 hicolor modes. Was conflicting with Viper boards causing them to crash the system.
• Added default GrafAlloc() and GrafFree() in Watcom lib that uses register passing.
• Virtualized memory segment alloc and free for Phar Lap 286 driver lib.
• Added support for Borland DPMI 286 dos extender.
• Converted Rational 16M support over to generic DPMI library.
• Added Phar Lap 286 keyboard fix for Windows.
• Added cntrl-sysreq toggle of keyboard events.
• Added support for VESA page flipping.
• Fixed bug concerning VESA drivers which returned winA attributes set to r/w and winB attributes to write only.
• Removed call to TextMode inside RasterOp since it conflicts with Borland RTL.
• Added Bezier support.
• Fixed bug with ReadImage() for monochrome, multiplane, EGA, VGA, when reading images that originate off the top of the bitmap.
