Yellow images from canvas DC?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all

I'm using the following code to create PDF:

PrnCanvas := TCanvas.Create;
PrnCanvas.Font.PixelsPerInch := DPI;

DC:=PDFLibrary.GetCanvasDC(PageWidth,PageHeight);
PrnCanvas.Handle := DC;

//draw something on PrnCanvas by some other library

PDFLibrary.NewPageFromCanvasDC(DPI,0);
...

Fonts and everything else is printed OK, but images are slightly yellow -> white is not white but yellow.
As I would have a yellow filter on top of image.

I tried with different images (png, jpg, bmp, ...), but the results are the same.

I tried to print this directly on printer (without QuickPDFLibrary) and there images are OK.

Any ideas how to fix this?

	Is it possible to send for you to send the PDF and the image file to us by creating a support ticket using http://www.quickpdflibrary.com/support/support-query.php Hopefully I can find a quick and easy solution. Andrew.
