Hi!
Precomp is a command-line file precompressor. It decompresses deflate/
zLib/LZW streams in files (for example PDF, SWF, ZIP, GIF, JAR, PNG)
and ensures they can be recompressed bit-to-bit-identical.
The output file is larger, but can usually be compressed better than
the original file with good compressors like UHArc or PAQ. PDF files,
for example, usually shrink to 25-50% of their original size.
I just uploaded Precomp 0.3.8. Change list:
- Files larger than 2 GB supported.
- Support for SWF files without slow mode.
- Updated packJPG to inofficial version 2.4WIP4 which improves
compression ratio for JPGs a bit.
- New switches -pdfbmp (BMP header for PDF images, useful for PAQ) and
-progonly (recompress only progressive JPG files, useful to leave the
other ones for PAQ).
- Speed up for decompression (30-150%), slow and brute mode (up to 4
times faster).
- It is possible now to run multiple Precomp instances in the same
directory.
