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%?
