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

Show in webframe

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 upon creating PDF file only by using PDF compressor.

File constants associated with this file format are:
