- -------- WHATS NEW IN TIF256 GRAPHICS LIBRARY EXTENSION V1.0b ---------
-
- The library files distributed for version 1.0b are exactly the same ones
- distributed for version 1.0. The difference is that the TIF_DEMO.C,
- TIF_DEMO.EXE, and TIF_DATA.EXE files reflect changes in the VSA256 Graphics
- Library V1.1b from which they are built.
-
- -------------- WHATS NEW IN VSA256 GRAPHICS LIBRARY V1.1b -------------
-
- 1.) Corrected a bug which caused it to improperly write to graphics memory
- (ie. not work) on Paradise cards (and any card which provides window
- resolution not equal to 64k). All the data used to pile up at the top
- part of the screen. Now it works correctly.
-
- 2.) Put in detection for VESA BIOS EXTENSION TSRs which do not support
- Text I/O in SVGA modes. In these cases (such as ATI driver) Graphics
- will still work but vsa_set_text_cursor, vsa_write_char,
- vsa_write_string, and vsa_write_string_alt now will do nothing (instead
- of trying to write and thus mucking up the display).
-
- 3.) Put in better exception handling to detect no VESA BIOS loaded, un-
- supported video modes, etc.
-
- --------------------------- Trouble Shooting --------------------------
-
- 1.) If Text seems to be readable but goes in wrong locations on screen,
- try manually changing the YCharResolution and YCharSize parameters
- after running vsa_init. Some of the older VESA BIOS TSRs report the
- wrong YCharsize value (ie. 8 pixels when really 16 ... Trident in
- mode 103 ... Paradise )
-
- 2.) Remember that programs which use the TIF256 Graphics Library Extension
- must be built with the LARGE memory model during compilation.
-
- 3.) You should specify a stack size of about 10,000 bytes for this stuff
- to work. (Otherwise you'll get "Stack Overflow").
