public Color GetPixelBilinear (float u, float v);


正規化座標(u, v)でフィルタリングされたピクセルのカラーを取得します

Coordinates u and v go from 0.0 to 1.0, just like UV coordinates in meshes. If coordinates are out of bounds (larger than 1.0 or smaller than 0.0), they will be clamped or repeated based on the texture's wrap mode.

Texture coordinates start at lower left corner. UV of (0,0) lands exactly on the bottom left texel; and UV of ((width-1)/width, (height-1)/height) lands exactly on the top right texel.


The texture must have the Read/Write Enabled flag set in the import settings, otherwise this function will fail. GetPixelBilinear is not available on Textures using Crunch texture compression.
