Summary: PDImageXObject: Add method getColorSpaces()
Key: PDFBOX-2297
URL: https://issues.apache.org/jira/browse/PDFBOX-2297
Project: PDFBox
Issue Type: Improvement
Components: PDModel
Affects Versions: 2.0.0
Reporter: Dominic Tubach
Attachments: PDImageXObjectColorSpaces.patch
PDImageXObject should contain the method getColorSpaces() to get the color
spaces that were passed to the constructor. I need it for the following use
case:
An image XObject may contain alternate images in the Alternates dictionary
entry. I want to create an PDImageXObject for one of the alternate images, so I
need the color spaces to pass them to the constructor. Theoretically a method
that returns a list of PDImageXObjects containing all alternate images would
also be possible. But as long as a PDImageXObject is always decoded it would
produce unnecessary overhead as I only need one of them.
