gimp_vectors_new ()

gint32              gimp_vectors_new                    (gint32 image_ID,
                                                         const gchar *name);

Creates a new empty vectors object.

Creates a new empty vectors object. The vectors object needs to be added to the image using gimp_image_insert_vectors().

image_ID :

The image.

name :

the name of the new vector object.

Returns :

the current vector object, 0 if no vector exists in the image.

Since GIMP 2.4
