ZSVGA DOS 32 Bit Protected Mode Graphics Lib

ZSVGA v1.01 (ZSVGA101.ZIP) is a 32 bit protected mode SVGA graphics library for the Watcom & Symantec C/C++ compilers. The library supports the 256 color resolutions (320x200, 640x400, 640x480,800x600, 1024x768 and 1280x1024) on 20+ SVGA video cards (in native mode) and all VESA video cards automatically with no effort from the programmer or end user. Every attempt has been made to achieve maximum speed, even at the expense of code size. All standard drawing functions have been implemented with automatic clipping at the screen edge or a defined window.

Features:

more than 100 functions and subroutines

100% assembly (80386sx or better processor required)

detection of video card/video memory/VESA support, mouse, joystick

choice of 5 drawing modes (NO_ACTION, SET, XOR, OR, AND)

plain & filled primitives (arcs, box, bezier, circle, ellipse, line & point)

fill functions (area, color, view, screen, page, convex & general polygons)

sprite functions (get, put, collision detection)

bitmap functions (get, put, rotation, scaling)

multiple page display support & page flipping

scrolling

palette functions (get, set, fading, rotating)

2d & 3d point rotation, scaling and translation, 3d projection

joystick support

fast trig functions

PCX encoding/decoding

complete documentation (in the include files), stand alone demo (with source code), complete examples (source code)
