NAME

gimp_layer_add_alpha - Add an alpha channel to the layer if it doesn't already have one.

SYNOPSIS

gimp_layer_add_alpha (layer)

DESCRIPTION

This procedure adds an additional component to the specified layer if it does not already possess an alpha channel. An alpha channel makes it possible to move a layer from the bottom of the layer stack and to clear and erase to transparency, instead of the background color. This transforms images of type RGB to RGBA, GRAY to GRAYA, and INDEXED to INDEXEDA.
