Hi,
I just made a one pager (TEXpage) out of a big png graphic (5900x4094).
The compressed size of the graphics is normally around 1.37MB on the
highest png compress level (9) and 1.32MB after using optipng (only
around 3% reduction this time). To my surprise the size of the final PDF
was about 2.3MB. After adding '\pdfcompresslevel9' the size went down to
1.48MB. Still not what I wanted...
So I was wondering: is there an option to embed the png graphic as it is
(no re-compression)? Otherwise the time consuming usage of optipng would
be a complete waste of time. Believe it or not, but size matters :-)
This one is for Hartmut to answer. Keep in mind that pdf does support
pgn and jpg compression, which is not the same as 'inclusion as-is'. The
compresslevel concerns copyright free zip compression of streams (that
can happen to gave image data).
