public Color GetPixel (int x, int y);


Devuelve el color del píxel en las coordenadas (x, y).

If the pixel coordinates are out of bounds (larger than width/height or small than 0), they will be clamped or repeated based on the texture's wrap mode.

Texture coordinates start at lower left corner.

If you are reading a large block of pixels from the texture, it may be faster to use GetPixels32 or GetPixels which returns a whole block of pixel colors.

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

See Also: GetPixels32, GetPixels, SetPixel, GetPixelBilinear.
