Portable Document Format (PDF). LEADTOOLS provides support for PDF compression with MRC segmentation. The MRC segmentation can be used to break down a page/image into smaller segments, saving each segment using compression appropriate for that segment. Thus, one page of a PDF file may have an image JPEG compressed, some text JBIG2 compressed, and another area CCITT compressed. This whole process works to provide a PDF file with better compression and better quality than just a standard Raster PDF file.
The default extension used by this format is: PDF.
LEADTOOLS supports Load and save for this format.
Keys that must be unlocked to enable this format support: Document. and PDF_ADVANCED.
Multi-page is supported.
File constants associated with this file format are:
| Constant | Read Support | Write Support | Description |

NOTE: PdfLeadMrc is made up of different segments, which can be of various BitsPerPixel. When you request file information on a PDF file, it will be reported as 24-bit. When you save PdfLeadMrc files, various segments will be saved with different BitsPerPixel, based on the content.
