Re: [PC4P-users] Bug in setting the compression factor? And a possible fix

Whoops, yes you're right...I fixed it in the CVS for now. Strangely you're
the first to complain, apparently noone ever used this function or simply
gave up on encountering that error. (and also it is obvious, that I never
really tested the function *blush*)

Quote from the manual:
"The PDF output will be compressed with the Flate (also known as ZIP)
compression algorithm. Compression can also be deactivated. Compression
applies to potentially large items, such as raster image data and file
attachments, as well as text and vector operators on page descriptions.
The compression speed/output size trade-off can be controlled with a
PDFlib parameter."
0 is no compression, 1 is best speed, 9 is best compression.
The manual gives no clue to the question, what the default is...hm

Regards,
Alexander
