METRIC CONVERSION MECHANISM FOR DIGITAL IMAGES IN A HIERARCHICAL, MULTI-RESOLUTION, MULTI-USE ENVIRONMENT

摘要

a mechanism to facilitate the metric conversion of digital images to be used in an environment multiapplication iterated and is included in the mechanisms for encoding and decoding the data so that the file hierarchy s of residual images stored in the memory containing information relating to the metric conversion.in a preferred mode of execution of the invention, the conversion is performed on a file with metric spatial resolution is relatively low.this produces a significant reduction of the treatment system since it takes advantage of the availability of the reduced size of the core file with low spatial resolution in a hierarchical database, so that we can make the metric conversion the relatively small number of pixels located in the fhichier baseto transform the image to obtain an image by enlarging the spatial resolution is relatively high, equivalent to 2048 x 3072 pixels per image for controlling a digital high resolution color thermal printer.
