DJGPP用 グラフィックライブラリ - ドキュメント
This package contains a replacement graphics library for DJGPP,
named "LIBGRX". It supports EGA, VGA, 8514/A compatible, and S3
based PC graphics adapters in 16, 256, and 32768 color modes.
Support for mono EGA/VGA, Hercules (the "original" monochrome)
should be coming soon. The library supports (among other things):
- an unlimited number of graphics drawing areas (called
contexts) both in video and system RAM.
- adjustable clipping regions for contexts.
- a rich set of graphics primitives.
- a library of loadable bit-mapped fonts.
- user to screen coordinate transformations.
