Hi Mark,
Thanks a lot for your response. I already thought of that workaround but was
hoping for a more "elegant" solution. Apparently there is nothing to
completely reset the graphics state to the default state directly?
I also figured out that pdf readers are rendering these kind of documents in
a different way. Adobe reader for example will render the imported pdf using
the current graphics state in the document (resulting in wrong display of
image). Foxit reader and others are using the default graphics settings for
the imported pdf in the document which results in a correct rendering of the
image. I dived into the Adobe pdf reference but cannot figure out which pdf
reader is behaving according to the pdf specs at this moment. For now I will
use your suggestion.
Thanks,
Bill

I'm afraid this one boils down to "Doc, it hurts when I do this".
Then Don't Do That.
If a particular page depends on a default value rather than explicitly
setting it, and that value is set prior to drawing the PdfImportedPage, then
the exlicit value will "leak through".
This is where the proper use of saveState/restoreState comes in. Going by
your sample code, you've mostly got the idea already. You just need to
restoreState all the way back to the default state before doing your
clipping and drawing your imported page.

Subject: [iText-questions] Appearance of PdfImportedPage object inconsistent
In some cases it is necessary to add pdf images and graphics to a document.
To do this I use PdfImportedPage. Unfortunately the appearance of the image
in the final document is not consistent but seems to be influenced by the
current graphics state of the document. When I use for example a dashed
stroke in the document the strokes in the imported image also become dashed
(in the original image they have been defined solid).
A similar issue occurs when text in the imported graphic pdf uses a same
font as the text in the document. In the imported pdf all fonts are embedded
(the same is true for the final document). In some cases the alignment and
spacing of characters differs from the original graphic.
It is not possible to change something in the imported images/graphics. Is
there a way to force a PdfImportedPage object to be treated as a seperate,
independent pdf without being influenced by graphics state of the document?
A snippet of the code being used:
.....
contentbyte.saveState();
contentbyte.rectangle(0, 0, 200, 200);
contentbyte.clip();
contentbyte.newPath();
PdfImportedPage image = writer.getImportedPage(reader, 1);
contentbyte.addTemplate(image, 1, 0, 0, 1, 0, 0);
contentbyte.restoreState();
.....
Thanks,
Bill
