Efl.Gfx.Mapping.mapping_uv

Description

Map point's U and V texture source point.

This sets/gets the U and V coordinates for the point. This determines which coordinate in the source image is mapped to the given point, much like OpenGL and textures. Valid values range from 0.0 to 1.0.

By default the points are set in a clockwise order, as such: - 0: top-left, i.e. (0.0, 0.0), - 1: top-right, i.e. (1.0, 0.0), - 2: bottom-right, i.e. (1.0, 1.0), - 3: bottom-left, i.e. (0.0, 1.0).

Since 1.22

Keys

  • idx - ID of the point, from 0 to 3 (included).

Values

  • u - Relative X coordinate within the image, from 0 to 1.
  • v - Relative Y coordinate within the image, from 0 to 1.
