PROBLEM TO BE SOLVED: To provide a method and apparatus for separately processing data of various kinds contained in a synthetic image or a synthetic document. SOLUTION: 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 that receives a first portion of the pixels, a background plane that receives a second portion of the pixels, and a selector plane 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, thereby executing document compression.
