I have a question about Erase colour.
I apply Erase colour using "Erase screen centre colour". Let's say I erased "green" under the screen centre. After that I want to erase some other colour near it. I move the screen centre to this place and apply Erase colour using "Erase screen centre colour" again. This particular colour is erased but the previous erased colour ("green") appears on the screen. Is it normal? What should I do if I want to erase a lot of colours by "Erase screen centre colour"?
Thanks.

Hi Alex,
Yes this is "normal", you can only erase one color.
This feature is mainly for maps that have white borders and or a white background which you want to remove.

If the colors are close, you can increase the erase color width (this will erase colors close to the one selected).

Best regards
