White margins - when white = light cyan

Post by eL_PuSHeR »

Hello.

I have another problem. Sometimes, when I process true-colour source images under ST, the output margins become cyan instead of white (I have double-checked that the white margins option is applied to all pages). Here is an example image. I get a cyan line at the top margin. Maybe you can't reproduce with just one page only. Sorry for the filesize. It's 2.5MB

PS: I think that rather than the margins themselves it's the underlying canvas differences after deskewing. I am not sure though.

Code: Select all

gm convert mot00page0033.png  -shave 22x22  -bordercolor white  -border 22x22  bordered.png
result:
