| LEADTOOLS Mixed Raster
Content Compression (MRC) Included in LEADTOOLS Document Imaging SDK's |
| The LEADTOOLS MRC compression
offers programmers the advantage of programming optimal compression for
documents that have both text and color images in the same file. Standard
compression schemes are geared toward an image being entirely text or
color, the MRC model offers the advantage of using optimal compression for
images that have both
text and color in the same image. This results in both high
compression factors and high detail retention.
LEADTOOLS MRC: Data Compression / File Compression for Documents Breaks an image into three different layers: foreground, background, and mask. Each layer is compressed separately using the best type of compression for that data type and is later uncompressed and recombined to restore the original image. For Example: A foreground layer contains color data for the text and line art, and may also contain photographic or continuous tone color data. The background layer generally contains low-resolution color image data, such as a background image, a wash or other pattern that would have text overlaid on it. The mask layer or the selector layer controls the process of image regeneration contains binary image data that is high spatial resolution, such as text and line art. This layer is used for drawing the corresponding foreground and background layers. Key Features:
