File Formats: LEADTOOLS PDF with Mixed Raster Content (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

Multi-page is supported upon creating PDF file only by using PDF compressor.

File constants associated with this file format are:

Constant	Read Support	Write Support	Description
FILE_RAS_PDF	24 BPP	N/A (see note below)	PDF Format with LEAD Mixed Raster Content.

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.

Required DLL: LCMRC, LCPDF, LCENC, LCZIB, LTSGM. For a listing of the exact DLLs needed, based on the toolkit version, refer to Files To Be Included With Your Application.
