PDF::Native

Description

This module provides a selection of native implementations of PDF functions.

Just installing this module along with PDF v0.5.7+ provides some increase in performance.

Currently, this module implements a hand-full of functions, mostly related to reading and writing larger PDF files.

So far, just a subset of potential areas are covered:

=item the PDF::IO::Filter::Predictor decode and encode functions. =item the widely used PDF::IO::Util pack and unpack functions. =item reading of cross reference tables and PDF 1.5+ cross reference streams. =item writing of strings, numerics, cross-reference tables and streams.

Classes in this Distribution

• PDF::Native::Filter::Predictors
• PDF::Native::Buf
• PDF::Native::Reader
• PDF::Native::Writer

Todo

Some other areas under consideration:

• C equivalents for other PDF::IO::Filter encoding functions, including predictors, ASCII-Hex, ASCII-85 and run-length encoding
• Support for type-1 character transcoding (PDF::Content::Font::Enc::Glyphic)
• Support for PDF::Content::Image, including color-channel separation and (de)multiplexing. GIF decompression de-interlacing.

There’s sure to be others.

Currently giving noticeable benefits on larger PDFs.
