# Clutter::Cogl::MaterialLayer(3pm)

## NAME

Clutter::Cogl::MaterialLayer

## METHODS

### materialfilter = $layer-\>get\_mag\_filter

Query the currently set magnifying filter for a cogl material layer.

### materialfilter = $layer-\>get\_min\_filter

Query the currently set downscaling filter for a cogl material layer.

### handle = $layer-\>get\_texture

This lets you extract a Clutter::Cogl::Texture handle for a specific layer.

**Note**: In the future, we may support purely GLSL based layers which will likely return *undef* if you try to get the texture. Considering this, you should call *Clutter::Cogl::MaterialLayer::get\_type()* first, to check it is of type 'texture'.

### materiallayertype = $layer-\>get\_type

Retrieves the type of the layer

Currently there is only one type of layer defined, 'texture'; but considering that we may add purely GLSL based layers in the future, you should write code that checks the type first.
