Static Image File Formats

JPEG	Joint Photographic Experts Group compressed format. This gives image quality nearly comparable to 24-bit plane bitmaps, but with a file of < 5% the equivalent size. JPEG format is supported by all common visualisation packages.
8 Bit Compressed BMP :	8-bit runlength encoded (RLE) Microsoft windows bitmap.
8 Bit Uncompressed BMP :	8-bit uncompressed Microsoft windows bitmap. The approximate size of the file is [image width * image height] bytes.
24 Bit Uncompressed BMP:	24-bit uncompressed Microsoft windows bitmap. The approximate filesize is [3 * image width * image height] bytes.
PNG:	24-bit lossless compressed Portable Network Graphics image. PNG offers the similar degree of compression as GIF but has better colour quality.
GIF:	8-bit lossless compressed Graphics Interchange Format.
PPM:	24-bit uncompressed Portable Pix Map. The approximate size of the file is [3 * image width * image height] bytes.
