# MaterialFilter

## Description:

[ CCode ( cprefix = "COGL_MATERIAL_FILTER_" , has_type_id = false ) ]

public enum **MaterialFilter**

Texture filtering is used whenever the current pixel maps either to more than one texture element (texel) or less than one.

These filter enums correspond to different strategies used to come up with a pixel color, by possibly referring to multiple neighbouring
texels and taking a weighted average or simply using the nearest texel.

## Content:

### Enum values:

- LINEAR - Use the weighted average of
the 4 texels nearest the current pixel center
- LINEAR_MIPMAP_LINEAR -
Select the two mimap levels whose texel size most closely matches the current pixel, use the
LINEAR criterion on each one and take their weighted average
- LINEAR_MIPMAP_NEAREST -
Select the mimap level whose texel size most closely matches the current pixel, and use the
LINEAR criterion
- NEAREST - Measuring in manhatten
distance from the, current pixel center, use the nearest texture texel
- NEAREST_MIPMAP_LINEAR -
Select the two mimap levels whose texel size most closely matches the current pixel, use the
NEAREST criterion on each one and take their weighted average
- NEAREST_MIPMAP_NEAREST -
Select the mimap level whose texel size most closely matches the current pixel, and use the
NEAREST criterion
