[reportlab-users] Reportlab and colors in Adobe Reader

Hello!

I am using ReportLab 2.4 for a month or so and I am VERY grateful for
this great tool which helps me automate doing large reports!

But I am stuck with an issue of colors. Appending a certain PNG Image
(generated by matplotlib) to the story changes colors. Affected are
colors in images, raw canvas drawings and text. I dont think it is a
ReportLab problem because Foxit and in Evince don't give me this kind
of color mixup. It looks like some kind of RGB/CMYK conversion thing.

I don't want to abuse this list for Adobe screw-ups, I would just
appreciate some assistance from the PDF experts. Here is a sample
document which displays colors on page 3 differently than on pages 1
and 2. Does anybody else see this same problem?

Does anybody know how to get Adobe's attention to investigate this
kind of problem?

Thank you in advance for any assistance,
Miha
