Enumeration

CoglPipelineFilter

Declaration

enum Cogl.PipelineFilter

Description [src]

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.

Members

Name Description
COGL_PIPELINE_FILTER_NEAREST

Measuring in manhatten distance from the, current pixel center, use the nearest texture texel.

COGL_PIPELINE_FILTER_LINEAR

Use the weighted average of the 4 texels nearest the current pixel center.

COGL_PIPELINE_FILTER_NEAREST_MIPMAP_NEAREST

Select the mimap level whose texel size most closely matches the current pixel, and use the COGL_PIPELINE_FILTER_NEAREST criterion.

COGL_PIPELINE_FILTER_LINEAR_MIPMAP_NEAREST

Select the mimap level whose texel size most closely matches the current pixel, and use the COGL_PIPELINE_FILTER_LINEAR criterion.

COGL_PIPELINE_FILTER_NEAREST_MIPMAP_LINEAR

Select the two mimap levels whose texel size most closely matches the current pixel, use the COGL_PIPELINE_FILTER_NEAREST criterion on each one and take their weighted average.

COGL_PIPELINE_FILTER_LINEAR_MIPMAP_LINEAR

Select the two mimap levels whose texel size most closely matches the current pixel, use the COGL_PIPELINE_FILTER_LINEAR criterion on each one and take their weighted average.
