Abstract:
1. A method for printing an image from a compressed file with rotation, comprising: accessing a compressed image file on a digital memory, the compressed image file having a plurality of data blocks that are compressed according to a compression sequence using incremental state information, wherein successive data blocks of the plurality of data blocks are compressed using incremental state information from an immediately preceding data block in the compression sequence; selecting a data block according to a printing sequence defining an order in which to print the plurality of data blocks for a desired image rotation, wherein the printing sequence is different from the compression sequence; obtaining, for the selected data block, corresponding incremental state information from the immediately preceding prior data block in the compression sequence stored in the compressed image file; decompressing the selected data block using the obtained incremental state information; printing the decompressed data block; and repeating the foregoing selecting, decompressing, and printing until the image has been printed with the desired rotation, wherein the printing sequence begins with a data block in the upper left hand corner of the compressed image and proceeds on a column basis, left to right.
