Abstract
A system and method of converting facsimile image data as received by any one of a plurality of fax cards into data stored in a file structure that assists use of the facsimile image by application software and which permits efficient processing of the image by a host computer. The data structure is composed of a file header containing information relating to the dimensions of the facsimile image as converted and stored, and pages of facsimile image data which include page headers that specify the number of pixels in each scan line. The pages further include byte-boundary-limited binary encoded run lengths and end-of-line characters at the ends of each scan line that are used to store the facsimile images. The data in representing the last run length of each scan line is not stored, but is determinable using other information in the pages. Multiple facsimile images can be stored in a single data file by storing separate images in different pages.
