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.

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?
