Andreas Lehmkühler commented on PDFBOX-927:
-------------------------------------------
This issue is about extracting images and PDFBOX-942 is about adding images to
a pdf. So I guess both are not related to each other.
I'd a look at the code. It just uses the embedded stream and writes the data to
the given output stream and it doesn't use the given colorspace. Maybe that is
the reason for the rendering issue. I treid to use the getRGBImage method and
to write the resulting BufferedImage to a file using ImageIO but I didn't work
either.
A possible solution could be to decode the stream using our own implementation,
which doesn't exist yet, instead of using the ImageIO and to apply the given
colorspace.
