Description

Hello,

I am calling convertToImage() with a multicolored, standard PDF-file and the resulting image does not contain the content of some colored stuff.

An example of such a PDF-file (v1.4) could be sent...

The same problem occurs in 1.5/1.4 and previous..., I 've also used the bleeding edge from repository (2011-04-04), the problem still exists.

Additionally, the following trace will be printed:
