Wrong color space used for DeviceN operator without color space specified
-------------------------------------------------------------------------
Key: PDFBOX-1128
URL: https://issues.apache.org/jira/browse/PDFBOX-1128
Project: PDFBox
Issue Type: Bug
Components: PDFReader, PDModel
Affects Versions: 1.6.0
Reporter: Simon Maskell
Priority: Minor
I have a PDF that uses a DeviceN color space, but when using the PDFToImage
utility I noticed that some of the text comes out as cyan.
I tracked the issue down to when the scn or SCN operator is used without
setting the color space explicitly (ie using the current color space). I have
attached a patch which resolves the issue by reinstating the original (DeviceN)
color space after using the alternate color space, otherwise the alternate
color space (in this case CMYK) was seen as the current color space and the
attribute of 1 for the scn operator, which was meant for the DeviceN color
space, is used in the CMYK color space resulting in the cyan.
I have also attached an example PDF and the result for the PDFToImage
conversion.
