png in pdf : acroread bug

If you put a png image in a pdf (with latex → pdflatex), it works with other viewers (evince, kpdf), but not correctly with acroread.

Please look at the screenshots :

kpdf : http://www.monsterup.com/upload/1212655058.jpg
acroread : http://www.monsterup.com/upload/1212655093.jpg

Is this bug already reported?

What's the issue? I couldn't see any difference between the 3 images. Please give more details about the issue.

Re: png in pdf : acroread bug

Look at the Fig. 2.1, in acroread the colors are wrong (very saturated), while they are ok with other viewers... This problem occurs with all png images included in a latex file.

Re: png in pdf : acroread bug

Try to include this screenshot in a .tex file, and compile it with pdflatex :

test.tex content :
----
\documentclass{report}

\usepackage[utf8]{inputenc}
\usepackage{graphicx}

\begin{document}
\begin{figure}
\includegraphics[width=8cm]{test.png}
\end{figure}
\end{document}

Re: png in pdf : acroread bug

In fact, it happens only with png with alpha channel.
But I heard it's normal because the pdf version is 1.4 so <1.5... Strange, because it works with other viewers...

I have to find how to make a pdf 1.5 with pdflatex...

Re: png in pdf : acroread bug

I added :
\pdfminorversion 5

So the generated pdf is pdf 1.5 (seen in pdf properties in acroread).

But the problem with png files still occurs.

To resolve the problem, I just remove the alpha channel (in gimp for example) of my png, and acroread displays it correctly.

EDIT: with \pdfminorversion 7 (pdf 1.7), acroread has no the bug.
png are correctly displayed.
