[jira] [Issue Comment Edited] (PDFBOX-994) some colors (HKS colors)
not in target image when calling
org.apache.pdfbox.pdmodel.PDPage.convertToImage()

--------------------------------------------------------------------
I dig deeper into this a came rto the following conclusions:
- the CMYK2RGB conversion works fine (I have to revise my former statement)
- I can't reproduce the exception
- the only issue left is the usage of some unsupported opacity/transparency effects within a extended graphics state which lead to the 2 black boxes in the middle and the solid black shadow of the 2 upper boxes
- it's not a duplicate of PDFBOX-963
Find attached the converted sample pdf using the current trunk (rev. 1135129)

> 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:
