                       unsigned edge ); 

Arguments:

layer

A pointer to a gf_layer_t handle of the layer you want to set the edge processing method for.

The filter edge processing method to use.

Can be any of the following values:

GF_LAYER_EDGE_NONE

none.

GF_LAYER_EDGE_CLAMP

Enable edge clamping mode.

GF_LAYER_EDGE_WRAP

Enable edge wrapping.

Library:

gf

Description:

This function allows you to set the edge processing type for a given layer.

Changes to the layer's parameters are enqueued. You need to call gf_layer_update() to make them take effect. The gf_layer_update() call will return something other than GF_ERR_OK if the layer doesn't have the GF_LAYER_EDGE_xxx attribute (see gf_layer_query()).
