Create a new layer from a GdkPixbuf
.
This procedure creates a new layer from the given GdkPixbuf
. The
image has to be an RGB image and just like with gimp_layer_new()
you will still need to add the layer to it.
If you pass progress_end
> progress_start
to this function,
gimp_progress_update()
will be called for. You have to call
gimp_progress_init()
beforehand then.
|
The RGB image to which to add the layer. |
|
The layer name. |
|
A GdkPixbuf. |
|
The layer opacity. |
|
The layer combination mode. |
|

|
end of progress |
Returns : |
The newly created layer. |
