When I create a PDF with a default ICC color profile and add an image created
by calling com.itextpdf.text.Image.getInstance(PdfWriter writer, Image
awtImage, float quality), iText is generating an invalid PDF where each
ColorSpace dictionary (in the page and nested XObjects) has another ColorSpace
entry which causes the failure. The sample code is below. Does anyone know
how to prevent the duplicate ColorSpace entry from being added? I don't have
this problem if I add images created by calling
com.itextpdf.text.Image.getInstance(String filename).
Thanks,
Peter
