LEADTOOLS PDF Programming Tools PDF Add-on from LEADTOOLS

The LEADTOOLS PDF SDK Plug-ins support loading, saving, viewing, rasterizing, and encoding of PDF, Postscript and EPS formats. In addition to this functionality, it integrates seamlessly with the broad imaging functionality present in the LEADTOOLS toolkits.

The PDF Read and PDF Write add-ons encompass specialized display, color-conversion, image-processing, scanning and much more. If you have a Document Imaging Product, you can also take advantage of annotations and document clean-up.

The LEADTOOLS PDF Read/Write Plug-ins are add-on modules for all LEADTOOLS Toolkits with exception of LEADTOOLS Multimedia. They extend these toolkits to support PDF, Postscript, and EPS formats.

PDF Reader Plug-in Below is a list of features unique to the PDF reader.

The PDF reader is available as an add on to Raster Imaging Pro, Document Imaging Toolkits, Medical Imaging Toolkits or our Vector Imaging Toolkit.

This plug-in also offers decryption capabilities as outlined here and can read the compression types supported by the PDF writer as described here.

Import Capabilities:

• Loads PDF 1.4 files.
• Loads PostScript Language Level 3 files.
• Loads EPS files.
• Support is provided for loading the entire document or a specified set of sequential pages.
• Decryption
  • RC4 40-bit key encryption.
  • RC4 128-bit key encryption.
• Support for User password, Owner password permissions.

Controlling page rasterization

• Pixel depth - Valid values are 1, 4, 8 and 24.
• Horizontal resolution in dots per inch.
• Vertical resolution in dots per inch.
• Ability to use fonts installed by the plug-in or system fonts.
• Font anti-aliasing - Valid values are 1-bit (no anti-aliasing), 2-bit and 4-bit.
• Graphics anti-aliasing - 1-bit, 2-bit and 4-bit.

PDF Writer Plug-in Below is a list of features unique to the PDF writer.

Full multi-page write support is provided by this module for the PDF format. You can append, insert, replace or delete a specified page in the generated PDF file.

The plug-in gives you a wide range of control options for the resulting image data in terms of compression. These include:

Export Capabilities:

• No compression, where the image is embedded inside the file without any compression.
• Compressed using CCITT Group 3, 1 dimension. For 1-bit images.
• Compressed using CCITT Group 3, 2 dimensions. For 1-bit images.
• Compressed using CCITT Group 4. For 1-bit images.
• JPEG compression and YUV 4:4:4 color space loss-less. Bits per pixel: 8 for grayscale, 24 for color.
• JPEG compression and YUV 4:2:2 color space. Bits per pixel: 8 for grayscale, 24 for color.
• JPEG compression and YUV 4:1:1 color space. Bits per pixel: 8 for grayscale, 24 for color.
• JBIG2 compression. Bits per pixel: 1.
• The plug-in also gives you control over the type of encoding to be used in order to change compressed image data into a text encoded format. The text encoding techniques include:
  • No text encoding at all.
  • Use ASCII 85 text encoding algorithm.
  • Use ASCII HEX text encoding technique.
• Encryption
  • RC4 40-bit key encryption.
  • RC4 128-bit key encryption.
• Support for User password, Owner password permissions.

Advanced PDF Compression (included in the PDF Write Plug-in)

The PDF Plug-in supports PDF compression through the PDF Compressor. Through Mixed Raster Content (MRC) segmentation, this compressor 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 that is compressed using JPEG compression, some text that is compressed using JBIG2 compression, and another area that is compressed using CCITT compression. This whole process works to provide a PDF file with better compression and better quality than just a standard Raster PDF file.

Advanced PDF Compression includes the following features:

• 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 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 G4compression 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.
