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.
Simple graphic format in color. Use 24 bits per pixel: 8 for red, 8 for green, 8 for blue if the maximum gray value is 255, uses 16 bits for red, 16 for green and 16 for blue if the value is greater than 255 and less than 65536. a PPM file is plain text and can be modified with a single processor, there is also not readable binary version of word processing normally. It is related to the PGM (grayscale) and PBM formats (black and white).
