- CLOANTO SOFTWARE UPDATE
-
-
- THIS ARCHIVE CONTAINS THE LATEST VERSION OF THE FOLLOWING LIBRARIES:
-
- - personal_agnus_blit.library
-
-
- PROGRAMS USING THE LIBRARIES:
-
- - Personal Paint version 7.0 and higher
- - ColorType version 3.1 and higher
-
-
- INSTALLATION DIRECTORY:
-
- - Default : "PPaint:libs", "ColorType:libs"
- - Optionally: "LIBS:"
- (software checks both paths and uses the newer library if two are found)
-
-
- ENVIRONMENT VARIABLES:
-
- - PBlit_Agnus (Yes/No/Auto)
-
-
- NEW FEATURES:
-
- In addition to containing blitting functionality based on the Amiga Agnus
- blitter logic, this library is queried on startup by programs like Personal
- Paint to determine whether the Amiga (Agnus) blitter is available for use.
-
- Based on the result provided on startup by this library, for example,
- Personal Paint might shadow the "Settings/Graphics/Amiga Blitter" option
- and automatically use a blitter emulation library instead.
-
- This new library is more flexible in deciding whether it is acceptable to
- use the Amiga blitter or not, allowing the user to make a choice in certain
- conditions where the previous library would have shadowed this program
- option. For example, certain CyberGraphX options which can be set by the
- user to use Fast RAM in certain conditions in which the system would
- normally use Chip RAM, will not cause the Amiga Blitter option to be
- disabled when using this new library. It remains up to the user, when
- experimenting with these non-standard system options, to manually disable
- the Amiga Blitter in the application if the new system settings cause
- incompatibilities.
-
- This library, like the previous versions, contains complex and up-to-date
- logic to detect a condition in which it might not be safe to use the Amiga
- blitter. This logic can be overridden by setting the "PBlit_Agnus"
- environment variable to Yes or No (default = Auto).
-
- Additional functionality has been integrated in this library to better
- support future programs.
-
-
- OTHER NOTES:
-
- As of version 2.0 of the blitting libraries, and up to a 68040 CPU the Agnus
- version is on average still faster than the 68K libraries. The Agnus
- blitting library can only work with bitmaps in Chip RAM.
