How to print a transparent png file on top of text

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

   I am working with quick pdf 17. Working/printing images works fine. But not I want to print a signature.png file (which is transparent) on top of text that is generated and printed on the pdf page. 
The result should look like a company/stamp signature on top of the text. 

I tried 
.SetPNGTransparencyColor(255 / 256, 255 / 256, 255 / 256)'
and
.SetImageMask(1, 1, 1, 0.1, 0.1, 0.1)
but is does not change... the image is printed with a fixed white background and destroying the text. 

I use the following simple code: 

   Call .AddImageFromFile(FileNameOfImageFile, 0)
   Call .SetPNGTransparencyColor(255 / 256, 255 / 256, 255 / 256)
   Call .FitImage(topX, topY, SizeWidth, SizeHeight, 1, 1, 0)

	Hi Ingo. thank you very much, the transparent bmp files did the trick when using the setimagemask I added this line just before the .fitimage call: Call .SetImageMask(0.9, 0.9, 0.9, 1, 1, 1) Call .FitImage(x,y,width,height, 1, 1, 0)
