Windows bitmap (BMP) format is a bitmap image, typical of the Microsoft Windows operating system. You can save images in 24-bit (16.7 million colors), 8-bit (256 colors) and less. Can these files be compressed without loss of quality: RLE (Run-length encoding). The bitmap files are composed of associated color coded addresses, one for each frame in a pixel array such as a picture of "colored boxes" for small children esquematizaría. Typically, they are characterized by being very inefficient in its use of disk space, but may show a good level of quality. Unlike vector graphics, to be rescaled to a larger size, they lose quality.
PCX, standing for Personal Computer Exchange, is an image file format developed by the now-defunct ZSoft Corporation of Marietta, Georgia. It was the native file format for PC Paintbrush and became one of the first widely accepted DOS imaging standards, although it has since been succeeded by more sophisticated image formats, such as BMP, JPEG, and PNG. PCX files commonly stored palette-indexed images ranging from 2 or 4 colors to 16 and 256 colors, although the format has been extended to record true-color (24-bit) images as well. PCX was designed during the early development of PC display hardware and most of the formats it supported are no longer used, Table A shows a list of the most commonly used PCX formats. Contemporary image editing programs may not read PCX files that match older hardware.
