Information about PPM and PNG file formats
|Full name||Portable Pixmap file||PNG - Portable Network Graphics|
|MIME type||image/x-ppm, image/x-portable-pixmap||image/png|
|Developed by||Jef Poskanzer||PNG Development Group|
|Type of format||Image File||lossless bitmap image format|
|Description||The portable pixmap format (PPM) is an image format designed to be easily exchanged between platforms used by Netpbm - an open-source package of graphics programs and a programming library, used mainly in the Unix world. The format is the lowest common denominator color image file format and is highly inefficient, containing a lot of information the human eye can't even discern. The precursor to the PPM format was the PBM format invented by Jef Poskanzer in the 1980s as a format that allowed monochrome bitmaps to be transmitted within an email message as plain ASCII text, allowing it to survive any changes in text formatting. By 1988, Poskanzer had developed the PGM and PPM formats and their associated tools and added them to Pbmplus. The final release of Pbmplus was December 10, 1991.||Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF) and is the most used lossless image compression format on the Internet. However, PNG itself does not support animation at all. MNG is an extension to PNG that does. Members of the PNG Group designed it.|
|Technical details||A PPM file consists of a sequence of one or more PPM images. There are no data, delimiters, or padding before, after, or between images. Each PPM image consists of the following: A magic number for identifying the file type. A ppm image's magic number is the two characters P6. Whitespace (blanks, TABs, CRs, LFs). A width, formatted as ASCII characters in decimal. Whitespace. A height, again in ASCII decimal. Whitespace. The maximum color value (Maxval), again in ASCII decimal. Must be less than 65536 and more than zero. A single whitespace character (usually a newline). A raster of Height rows, in order from top to bottom. Each row consists of Width pixels, in order from left to right. Each pixel is a triplet of red, green, and blue samples, in that order. Each sample is represented in pure binary by either 1 or 2 bytes. If the Maxval is less than 256, it is 1 byte. Otherwise, it is 2 bytes. The most significant byte is first. There is another version of the PPM format that is fairly rare: plain PPM format.||PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB[A] images (with or without alpha channel). However, PNG was designed for transferring images on the Internet, not for professional-quality print graphics, and therefore does not support non-RGB color spaces such as CMYK.|
