Hello,

When I render a pdf to a jpg the transparent image appears with a grey background.
I tried flattening the image and tried to see if I could raster the image, however I had no luck,

Below is the code as well as the original and converted file.

# Code
if (PDFLibrary.RenderDocumentToFile(300, 1, 1, 1, output) > 0)
{
     ...
}

Hi Andre,

the urls only show two images?
Don't know how to download them...
Anyway: Try a CombineContentStream and NormalizePage after load and before rendering.
If there isn't any success try other image formats to look for better results.

Cheers and welcome here,
Ingo

Cheers,
Ingo

G'day Ingo,

Thanks for your reply :) always appreciated,

I tried the above mentioned, however I had no luck, I had to use a different method in order to achieve this.

Also my apology's for not upload raw files, I couldn't find how to do it,

Thanks again, hope all is well on your end.
