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 for 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 ^
