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. 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.
