General ⇒ beamer | Fading Colors (possibly caused by Images)

[TamasFGorbe]

Hi,

I'm working on a presentation and I have the following problem.

All colors in a frame fade when the frame contains an image (inserted by using simple \includegraphics)(like there would be a light gray layer on the frame). But there are other frames which also have pictures in it and their color are fine (not faded). First I thought that it's because the pictures from different sources but it's not the case. And the best part that this fading effect occurs only when I open the PDF file adobe reader <-> in texmakerx' viewer everything works OK and the colors are unchanged. Is there a simple solution?

(I hope that my description was clear :\ )

Hi Tamas,

the Adobe Reader is known to have problems with transparency in images. So this problem could be caused by including PNG images with transparency (alpha channel), for example. I suggest to edit such images with a graphics program and to remove the trasparency.
