Methods for generating anti-aliased text and line graphics in compressed document images |
摘要 |
A method and system for storing and generating anti-aliased text and lineart data from compressed document image files, using a MRC model that represents the image as an ordered set of mask/image pairs at resolutions appropriate to the content of each layer. The method and system provide the ability to generate for anti-aliased text data to improve appearance at both high and low resolution, and to avoid baseline jitter of compressed tokens.
