MPC

RW

Magick Persistent Cache image file format

The native "in-memory" GraphicsMagick uncompressed file format. This file format is identical to that used by Open ImageMagick to represent images in memory and is read in "zero time" via memory mapping. The MPC format is not portable and is not suitable as an archive format. It is suitable as an intermediate format for high-performance image processing.

The MPC format requires two files to support one image. When writing the MPC format, a file with extension ".mpc" is used to store information about the image, while a file with extension .cache stores the image pixels. The storage space required by a MPC image (or an image in memory) may be calculated by the equation (QuantumDepth*Rows*Columns*5)/8.

PNM is a family of formats supporting portable bitmaps (PBM) , graymaps (PGM), and pixmaps (PPM). There is no file format associated with pnm itself. If PNM is used as the output format specifier, then GraphicsMagick automatically selects the most appropriate format to represent the image.
