Graphics32 is a free graphics library for Borland Delphi and Kylix optimized for 32-bit pixel formats which is licensed under the Mozilla Public License.. Graphics32 provides fast operations for pixels and graphic primitives and is almost a hundred times faster in per-pixel and about 2–5 times faster in drawing lines access than the standard components by Embarcadero which are wrappers for ...
Watcom C/C++ was a commercial product until it was discontinued, then released under the Sybase Open Watcom Public License as Open Watcom C/C++. It features tools for developing and debugging code for DOS, OS/2, Windows, and Linux operating systems, which are based upon 16-bit x86, 32-bit IA-32, or 64-bit x86-64 compatible processors.
Computer Graphics: Principles and Practice is a textbook written by James D. Foley, Andries van Dam, Steven K. Feiner, John Hughes, Morgan McGuire, David F. Sklar, and Kurt Akeley and published by Addison–Wesley.
The Enterprise computer has five graphics modes: 40- and 80-column text modes, Lo-Res and Hi-Res bit mapped graphics, and attribute graphics. Bit mapped graphics modes allow selection between displays of 2, 4,16 or 256 colors (from a 3-3-2 bit RGB palette), but horizontal resolution decreases as color depth increases.
Attribute clash (also known as colour clash or bleeding) is a display artifact caused by limits in the graphics circuitry of some colour 8-bit home computers, most notably the ZX Spectrum, where it meant that only two colours could be used in any 8×8 tile of pixels.
A region is specified (after initial creation) by an opening of the region, drawing various QuickDraw shapes, and closing the region. Hidden routines construct the region as the QuickDraw commands are executed. Bitmaps may also be converted to regions, and bitmaps may be made from regions by "painting" or "filling" the region into a graphics port.
Bit depth The number of bits per pixel, sample, or texel in a bitmap image (holding one or more image channels, typical values being 4, 8, 16, 24, 32) Bitmap Image stored by pixels. Bit plane A format for bitmap images storing 1 bit per pixel in a contiguous 2D array; Several such parallel arrays combine to produce the a higher-bit-depth image ...
The first release of GPC was designed and implemented in 1997 by Alan Murta. As of August 2009 the final GPC release was version 2.32. The core GPC library is written in the C programming language but the library has also been ported to work with several other languages.
