/***************************************************************************** * * * Filenanme : DEMO.C * * This is an example program that demonstrates use * * of the most commonly called LEADTOOLS functions. * * This will be a guideline for developers to call * * and use LEADTOOLS compression/decompression, * * viewing, conversion, and all the BitMap load, flip, * * reverse functions for both TARGA and VGA/SuperVGA * * graphics card. * * * * This example uses both TARGA and VGA display in the same * * program. If your application uses only the TARGA display * * then do not use the L_Load???Screen() functions (where * * ??? is the file format). Also, if you are writing only * * for VGA display, then do not use the L_Load???Targa() * * functions. If both are used, then the EXE file will be * * larger than necessary since these routine are not * * applicable to the hardware. * * * ***************************************************************************** ***************************************************************************** * PROGRAMER: MOHAMMAD DAHER * * DATE: 03/12/1992 * * Last Modified: 3/26/92 * * * * COPYRIGHT (c) LEAD Technologies Inc.
