PDF: Writing PDF

The LEADTOOLS PDF Write Plug-in is an add-on module for all LEADTOOLS Toolkits. It provides full multi-page write support for the PDF format.

For complete instructions on unlocking PDF support and implementing PDF features, see the appropriate Raster Imaging help file.

With this plug-in, you can:

§ Append, insert, replace or delete a specified page in the generated PDF file.

§ Control options for image data compression, including:

q No compression, where the image is embedded inside the file without any compression.

q Compressed using CCITT Group 3, 1 dimension. For 1-bit images.

q Compressed using CCITT Group 3, 2 dimensions. For 1-bit images.

q Compressed using CCITT Group 4. For 1-bit images.

q JBIG-2 compression for 1-bit images.

q JPEG compression and YUV 4:4:4 color space loss-less. Bits per pixel: 8 for grayscale, 24 for color.

q JPEG compression and YUV 4:2:2 color space. Bits per pixel: 8 for grayscale, 24 for color.

q JPEG compression and YUV 4:1:1 color space. Bits per pixel: 8 for grayscale, 24 for color.

q LZW compression for bits-per-pixel: 1, 2, 4, 8, 24.

§ Control the type of encoding to be used in order to change compressed image data into a text encoded format. The text encoding techniques include:

q No text encoding at all.

q Use ASCII 85 text encoding algorithm.

q Use ASCII HEX text encoding technique.
