File Formats: LEADTOOLS PDF with Mixed Raster Content (PDF)

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: L_SUPPORT_DOCUMENT.

Multipage is supported when creating a PDF file only by using the PDF compressor.

File constants associated with this file format are:

Constant Read Support Write Support Description
