[Gs-devel] Re: [Gs-code-review] PDF inflator

[Ray Johnston]

Dear Suzuki-san,

I don't know when I will be able to return to work on the inflator,
but be aware that this tool will still create binary data in the
streams. The only thing that it changes is the FlateDecode streams
in the original are written without the compression.

It could be that the tool will work for your testing. I tested
about 35 files and 8 of them failed to produce output that could
be read by GS and Acrobat Reader.

Also, let me take this chance to thank you for your work with
Ghostscript and in helping us improve the CIDFont support.

Regards,
