"Include background color when saving tiles to an image" AND "Combine background color data with transparent tile layers" options when saving as an image, would come in VERY handy as I am currently using Gimp to add a black background to the image and then deleting the top most black area as it is used for the alpha 0 transparent sky area in our background. The additional option would reduce several steps in our workflow and the need for an external photo manipulation program.
would be very usefull i think!!!
I do not understand what you mean with "Combine background color data with transparent tile layers". Is that still needed with #637 accepted and if so, could you elaborate on what you meant?
