gint32 gimp_layer_new_from_pixbuf (gint32 image_ID, const gchar *name, GdkPixbuf *pixbuf, gdouble opacity, GimpLayerModeEffects mode, gdouble progress_start, gdouble progress_end);
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.
image_ID : |
The RGB image to which to add the layer. |
name : |
The layer name. |
pixbuf : |
A GdkPixbuf. |
opacity : |
The layer opacity. |
mode : |
The layer combination mode. |
progress_start : |
start of progress |
progress_end : |
end of progress |
Returns : | The newly created layer. |
