1. When exporting a page as PNG, the png background is completely black all the time.
I tried setting the page color, but it does not affect the PNG export.
How do I get the PNG to have a white or transparent background?
2. JPG works just fine, except I do not see any difference in the JPG when setting compression to 0 or to 255... there should be a big difference.
What is the range of the compression? 0-255 or 0% to 100%?
Any support here?
Hi,

It may be helpful to use Your name, not just throw something into a post.
1) If the PNG background is black, maybe this is because of the bit depth. In monochrome images this can happen. Which method do You use to export PNG?
2) in case You use pdfMakeJPEG, the compression is stroed in the secod word of "jpegres" as 0..100
You need to shift the value left by 24 bits

For monochrome, I use pdf.CommandStr(COMPDF_MakePNGMonochrome,s)
For 256 colors, I use pdf.CommandStr(COMPDF_MakePNG,s)
and for true color, I use pdf.CommandStr(COMPDF_MakePNGRGB,s);
But whatever I use, the colored PDF document comes out always with a black background after exporting, so text cannot be seen...
Hi,
Maybe it is something in this specific PDF.
You can of course mail it to me, so I can try it out here.
