Sorry, my mistake: when I started to look deeper in the results of my regression tests I encountered that I got huge problems with beamerexample1.pdf, there I got "dancing colors". And I thought that the reason was that the formula often runs into the clipping of pixels which sometimes "random" values. I thought that the reason was the usage of this lossy compression, and ignore this in a first step. After I got all other samples running I forgot that and upload the patch before thinking again about it.... But today I wasn't no more satisfied with that explanation and searched and searched what the reason could be, and I was just one step away to give completely up, but finally I now found the reason: In the PDF of <a href="show_bug.cgi?id=22473#c13">comment 13</a> AND in the beamerexample1.pdf the alpha values were inverted (Decode [1 0]!!), and instead of use this for the matte color I have to correct the alpha value in the formula!</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
