Andreas Lehmkühler commented on PDFBOX-580:
-------------------------------------------
survey.pdf from our rendering test arena [1] is a suitable sample for this issue

> Use a dummy color instead of failing with unsupported color spaces

> At work we encounter some PDF files with color spaces that PDFBox does not
> support. Currently an IOException gets thrown whenever such color spaces are
> being accessed, which is not ideal especially (as often is the case) when the
> troublesome color space is only used for some small part of the document. It
> would be nicer if PDFBox just logged a warning about the problem and used
> some dummy color for the entire troublesome color space.
> For the record, the IOException trace we're seeing is:
> org.apache.pdfbox.pdmodel.graphics.color.PDColorState java.io.IOException:
> Not implemented java.io.IOException: Not implemented
