One of my customers becomes some times scanned documents, where black and white are exchanged(whinte fonts on black background). Other software displays documents correct (for example Edge or PDFXchange Viewer). I have figured out that those documents are created with PDF24 programm. Unfortunatly i can not give you an example because they contains businis secrets and personal information of other peaple. Could you perhaps help me to fix this behaviour.
I examen one Document structure with itext rups. It seems that embeded Pictures are realy with swaped colors. Perhaps I have to Config Control right way to display Document correctly. I use default PdfViewer settings.

Hi Alexander,
There is a known issue in RadPdfViewer related to images which are compressed with CCITTFaxDecode. You can find more information about this case in the related public item: PdfViewer: Images compressed with CCITTFaxDecode with BlackIs1 parameter are rendered with inverted black and white colors.
It seems like you are hitting the same case but I cannot confirm that without testing a document. Is it possible to create an example document without the sensitive data and share it? Additionally, you can submit a support ticket through our system where the threads are private. I can assure you that we treat all the customer documents in a strictly confidential manner and use them only for testing purposes.
