Welcome to this demonstration program ^
^
In the following frames, I will show features of most of the ^
routines in the Library. ^
^
These routines are specifically for VGA hardware, allowing ^
developers to incoroporate these features without overhead ^
of supporting older boards ^
^
This Library also offers much more capabilities than that ^
which comes with high level language compilers. ^
^
Specifically :- ^
^
All primitives by direct video buffer updates ^
^
BIOS used for colour registers updates only ^
^
VGA standard and extended modes ^
640x350x16 mode no 10h ^
640x480x16 mode no 12h ^
320x200x256 mode no 13h ^
640x400x256 mode no 5ch ^
640x480x256 mode no 5dh ^
800x600x16 mode no 5bh ^
1024x768x16 mode no 5fh ^
^
80286/386 instructions used ^
^
Assembly language implementation of Bresenham algorithms ^
of lines and ellipses ^
^
Assembly language implementation of Sutherland-Cohen line ^
clipping algorithm ^
^
Another option of drawing ellipses and arcs by 2nd order ^
differential algorithm ^
^
Area and Polygon Fill with user definable patterns ^
^
Viewports which can be mapped to world co-ordinates ^
^
Bit-mapped and Stroked Fonts ^
^
8x8 Stroked Font editor ^
^
Bit-Block moves, and Image copy within video buffer using ^
VGA write mode 1 ^
^
Pixels panning and split screens ^
^
colour manipulations ^
^
2D transformations ^
