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.
Truevision TGA, often referred to as TARGA, is a raster graphics file format created by Truevision Inc. (now part of Avid Technology). It was the native format of TARGA and VISTA boards, which were the first graphic cards for IBM-compatible PCs to support Highcolor/truecolor display. This family of graphic cards was intended for professional computer image synthesis and video editing with PCs; for this reason, usual resolutions of TGA image files match those of the NTSC and PAL video formats. TARGA is an acronym for Truevision Advanced Raster Graphics Adapter;TGA is an initialism for Truevision Graphics Adapter.
