All, I'm using iTextsharp and noticed a color shift in an image after a page import using PdfWriter. The reason for the change in color is that the Transparency Group dictionary in the imported page object is not being preserved when the page is being imported into an XObject Form. I'm assuming the Java version works the same way.
So my question is, shouldn't the Transparency Group be preserved in the resulting XObject Form when a page is imported? Without it, the imported page will display differently in Acrobat and the visual differences can be very noticeable. There are some excellent discussions on the mailing lists on the subject of Transparency Groups, but I did not see this problem being specifically discussed. It seems to me that one should not have to manually insert a Group dictionary following a page import as the GetImportedPage() method should be responsible for making sure the imported page is kept intact. The PdfCopy works fine (and PdfStamper presumably as well), but in that case the imported page object is preserved as-is as opposed to being converted into an XObject Form.
