zlib-flate -compress=[9] < [input] > [output.zz]
Decompress a raw zlib stream from a PDF
zlib-flate -uncompress < [stream.bin] > [decoded.txt]
说明
zlib-flate performs raw zlib compression and decompression. It reads from standard input and writes to standard output, making it suitable for use in shell pipelines. The tool uses raw zlib compression format, which distinguishes it from utilities like gzip that add wrapper headers. Compression levels from 1 (fastest) to 9 (best compression) can be specified with the -compress= option. zlib-flate is included as a utility in the QPDF package. It is primarily provided as a debugging tool for working with raw zlib streams such as those found inside PDF files. It should not be used as a general purpose compression tool; use gzip instead for that.
参数
- -compress
- Compress data.
