Abstract
A computer program product for compressing data files representative of an image document. The document includes color information and/or graphical information. The product is on a computer readable medium and includes instructions for causing a computer to provide a first image file at a first resolution and a second image file at a second resolution of said document with said second resolution being lower than said first resolution. The product causes a computer to process the first image file to convert the first image file into a text file representation of the document and compress the text file representation of the document to provide a first compressed file. The computer processes the second file to extract information corresponding to color information and graphics information. It compresses the second file using a second, different compression technique to provide a second compressed file corresponding to the image and the color information from the low resolution image file. The product causes a computer to store said first and second compressed files to provide a composite file corresponding to the compressed file of the document.
