The LEADTOOLS PDF Plug-ins are add-on modules for all LEADTOOLS Toolkits with exception of LEADTOOLS Multimedia and extends support to include PDF, Postscript, and EPS formats. The LEADTOOLS PDF SDK Plug-ins support loading±, saving, viewing±, rasterizing±, and encoding of these three formats and integrates seamlessly with the broad imaging functionality present in the existing LEADTOOLS toolkits, encompassing specialized display, color-conversion, image-processing, scanning, annotations **, document clean-up **, and much more.

- Supports many compression types:
- ZIP ( Flate compression )
- LZW
- FAX CCITT ( G3 1D, G3 2D, G4 )
- JBIG2
- Lossless JPEG
- JPEG ( YUV 4.4.4, YUV 4.2.2 and YUV 4.1.1 )
- Works in 2 modes in the page level:
- MRC mode: enables the segmentation of the source image and then compresses the resulting segments.
- Normal mode: inserts the image into the PDF file without segmentation.
- Produces v1.4 (Adobe Acrobat 5.X) PDF files.
- Provides advanced options to control the process of adding the segments to the PDF file.
- Provides input profiles to specify source image quality. This makes controlling the segmentation process simple and more accurate. The input profiles supported are:
- Automatic
- Noisy
- Scanned
- Printed
- Computer generated
- Photo
- User: This profile is provided for advanced users.
- Provides output profiles to specify required output quality. This should also make the segmentation process easier and more accurate. The output profiles supported are:
- Automatic
- Poor
- Average
- Good
- Excellent
- User: This profile is provided for advanced users.
- Provides control over the compression types that will be used with each type of segment. For example, the user can choose to use the FAX CCITT G4 compression type to handle 1 bit/pixel segments.
- Background detection is supported. The user can enable background detection which will try to determine the background of the image. In that case, the PDF Compressor will NOT store the background segments, which results in more compact PDF files.
Background is created using shapes instead of image segments. This reduces the size of the resulting PDF file. - Control over 1Bit and 2Bit segment detection: The user can choose 1Bit segments over 2Bit segments and vice versa. The user can also choose to force 1Bit segments over 2Bit segments and vice versa.
