I try to convert the first page of a book to a png, scale the png to a certain size and add a black border. This is what I tried:
convert tmp.pdf\[0\] -background white -alpha remove -border 8 -bordercolor black cover.png
This is the document, I want to convert.
For some reason I have to specify
-background white -alpha remove since otherwise my white border does not appear or is grey. My problem is that the border that is added is grey not black. Is there anything I can do?
