 | Mrc Class |
The optimization profile suitable for documents with Mixed Raster Content
Reduce the file size for documents containing large images, e.g. scanned pages, while maintaining the readability of text. This is accomplished by separating the images into a foreground, background and a mask layer. The foreground and background layers are heavily down-sampled and compressed. The textual information is stored in the mask with a lossless compression type. Additionally, redundant objects are removed, resources are optimized and embedded fonts are merged.
