Plot transparent bitmaps

[sugeng anto]

When exporting / plotting eeschema have bad result for image object (for example : company logo)
I add image from png file which has transparent background.

1. Exporting to pdf create black background for image.
2. Exporting to SVG only image outline is printed (viewed using firefox browser)
3. Exporting to post script create black background for image (view using GSview)
4. Plot to clipboard results correct image. With transparent background, but I assumed this is right. But the image is truncated on lower right. (pasted to paint.Net)

Sorry but at the moment most of the plotter simply don't support transparent images... for *some* of them it could be fixed, for others there is no hope (postscript simply doesn't allow transparency without some optional extentions)

can we at least map transparent to white?

[Jason Pyeron (jpyeron)]

better yet, how about invert on plot? that might even be easier

This would be a big (read expensive) feature, and there aren't enough users behind it to do it instead of something else.
