Abstract
Abstract A method of compressing text and graphic images for storage on a computer memory device. The first step of the invention is the importation of a TIFF or EPS file to be compressed into a conversion program where it is converted to a JPEG or PICT filt type. The next step is to import the converted file into a basic authoring program that is written to allow importation of JPEG or PICT files. Once the file has been inserted into the authoring program, a standard compressor is selected and used to perform compression, such compressors being preferably "CINEPAK" of JPEG. Once the file-images have been compressed to a level desired, the images are then stored or fixed or transmitted in their compressed form in their new file-type. The next step is the decompression of the file-images and the viewing thereof. When the compressed file is selected for viewing, a decompression and conversion program is run to decompress the file and convert it back into its original file-type, TIFF or EPS, at which time, it may be processed by an OCR program.
