Abstract:
1. A method of compressing a digital image comprising: dividing, by a processor of a computing device, the image into cells of constant physical size regardless of resolution of the image to produce cell data for each cell which defines content of the cell, where prior to dividing the image into the cells of constant physical size, and prior to any type of compression being performed on the cell data of the cells after dividing the image into the cells of constant physical size, the image is a multiple-resolution image such that a first portion of the image is at a first resolution and a second portion of the image is at a second resolution different than the first resolution; and, compressing the cell data of the cells on a cell-by-cell basis, where the cell data of each cell is compressed in accordance with a resolution of the cell prior to any type of compression being performed on the cell after the image has been divided into the cells, wherein prior to any type of compression being performed on the cell data of the cells after dividing the image into the cells of constant physical size, a first cell encompasses a first number of pixels of the first portion of the digital image that is at the first resolution, and a second cell encompasses a second number of pixels of the second portion of the digital image that is at the second resolution, the first number of pixels being different than the second number of pixels.
