John Hewson commented on PDFBOX-3375:
-------------------------------------
They can parse the tags (they easy bit) but that's it. They don't parse any of
the color data (the hard bit) or implement any of the color transforms (the
really hard bit). We've looked into using commons-imaging in the past but none
of there code is complete enough for PDFBox and the project has only a handful
of minimally active maintainers.

> In PDDeviceRGB the non-static init method is synchronized using the instance
> of the class as lock object. So far so good. But as the class is used a
> singleton a static object has to be used as lock object.
