Mixed raster content

Mixed raster content (MRC) is a method for compressing images that contain both binary-compressible text and continuous-tone components, using image segmentation methods to improve the level of compression and the quality of the rendered image.[1] By separating the image into components with different compressibility characteristics, the most efficient and accurate compression algorithm for each component can be applied.

MRC-compressed images are typically packaged into a hybrid file format such as PDF. This allows for multiple images, and the instructions to properly render and reassemble them, to be stored within a single file.
