Abstract:
1. A method for section-by-section processing of a digital image file in an imaging device, comprising: selecting from an image data file a yet un-decompressed section which makes up less than the whole image file; decompressing the selected section; color-space transforming the decompressed section in accordance with parameters of the image data file and an output device; resizing the color-space transformed section; half-toning the resized section; storing the half-toned section; and repeating, seriatim, the selecting, decompressing, color-space transforming, half-toning and storing steps until the whole image file has been so processed, wherein the imaging device processes the digital image file section-by-section; and when a selected section is the same as the last previously processed section, skipping the decompressing, color-space transforming, and resizing steps, and performing the half-toning and storing steps on a decompressed, color-space transformed, and resized version of the last-processed section to produce a processed section for the selected section.
