Description PGM files are known as portable graymap files and contain grayscale image information. These files can be saved in two representations, either as plain (ASCII) text or binary. In which way the PGM is saved is apparent in the file header. If the header contains the string "P2" it is a text format, if it contains the string "P5", it's a binary representation. Binary PGM files can contain more than one image. This is not possible for the text-based PGM. It is limited to one image. The BMP file format, also known as bitmap image file or device independent bitmap (DIB) file format or simply a bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device, especially on Microsoft Windows and OS/2 operating systems.
Technical details Portaple Gray Map Images can be encoded using either one byte or two bytes per pixel, representing either 8 or 16 bits. The file header contains different information such as the width and height of the image and the maximum number of black and white shades. The information is stored in a grit format, consisting of different numbers. These numbers represent the grayscale shades of the image, ranging from black (0) to white (65.536). The bitmap image file consists of fixed-size structures as well as variable-size structures appearing in a predetermined sequence. Many different versions of some of these structures can appear in the file, due to the long evolution of this file format.
