Hi,

I've looked back through the message archives on this and found a few questions
related to this, but no solutions. Through both the PDFToImage command line tool
and the convertToImage() method, some pictures in PDFs come out with
multicoloured 'bands' across them, or are made more severely illegible. From
iterating through the properties of the images in a sample document, it looks
like this happens to PNG images which use a DeviceRGB ColorSpace, but those that
use an Indexed Colorspace are fine.

An issue that demonstrates the problem, with 'before' and 'after' images, is
https://issues.apache.org/jira/browse/PDFBOX-958 .

Does anyone have any further ideas as to what might be going on, or what could
be done to fix or work around this? The issue seems to be somewhere in or below
the getRGBImage() method, as images written straight out from here already show
the deterioration, before they're included in a complete PDF page image.
This issue is fixed in the current trunk. See PDFBOX-958 for further details.
