I am trying to create a PDF file from some application. Please note that the picture in this application has the black background. So I invoke a Print command and set a printer as "Adobe PDF". As a result, I have generated
a brilliant PDF file of my picture, but on the WHITE background. When selecting the Adobe PDF printer, I have looked through all its settings ( in the Adobe PDF settings, I have found several tabs: General, Images, Fonts, Color, Advanced, PDF/X), none of them generated the original background color.
So how can a generate a PDF file, having the original background color (black, in my case) ?
