ABSTRACT:
A method of compressing a document includes: acquiring an image of the document, the image represented by pixels; segmenting the image into Mixed Raster Content (MRC) planes including a foreground plane (12) that receives a first portion of the pixels, a background plane (14) that receives a second portion of the pixels, and a selector plane (16) that identifies which of the foreground and background planes the pixels belong to; identifying a geometric shape in at least one of the MRC planes; determining if the identified geometric shape has a substantially uniform color; and, replacing the identified shape when it is determined to have a substantially uniform color with a vector graphic representation of the geometric shape.
