6.9. Flatten Image

Accessing the Flatten Image menu item.

This command can be accessed from an image menubar as Image->Flatten Image.

"Flatten Image" causes all of the layers of the image to be merged into a single layer with no alpha channel, with the same appearance as the full image viewed from the top. If there are any areas with transparency all the way through to the bottom of the layer stack, they are mixed with the image's background color. This operation is performed as part of the process of exporting an image, if you save it in a format that does not support layers.
