Beamer + pdflatex output looks crappy in Flash-based pdf viewers

Hi,

I faced a weird problem when uploading slides made with Beamer to
Slideshare and Scribd. If I compile the slides with pdflatex, the
edges of all blocks (exampleblock, alertblock etc.) will look crappy -
see slide number 2 for example:

http://www.slideshare.net/linjaaho/latex-and-slidesharefinnishfinal-7275984

The problem can be "solved" by using latex+dvips+ps2pdf instead of
pdflatex, but that is a problem if I want to use jpg and png images in
my slides (latex+dvips+ps2pdf requires using eps images).

Before submitting a bug report to Beamer and/or Adobe, I'm asking if
anyone has faced or even solved this problem.

Friendly regards,

Vesa Linja-aho

Just convert the images using ImageMagick or equivalent.

Thank you for your advice. I accidentally found one way more (didn't
know that pdftex can output dvi):

pdflatex --output-format dvi filename.tex
dvips filename.dvi
ps2pdf filename.dvi

This way you can get rid of those crappy dots AND use jpg&pnd without
converting them to eps.

Yes, or simply say \pdfoutput = 0 at the very beginning of your .tex
source...

Sorry, but pdflatex in dvi mode /cannot/ include JPEG or PNG

the files was hanging around.

"LaTeX Error: Cannot determine size of graphic in animated.png (no
BoundingBox)."

You are right and I was wrong.

Update to this issue: the bug is *not* in Beamer, it was in the Flash-
based renderers. Scribd has already corrected the bug, Slideshare will
correct it to the next release, see:
http://www.slideshare.net/linjaaho/beamerbug-8578652

Case closed, at least I hope so,
