> 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:
