ufoRasterGetPixelAl pha

    void ufoRasterGetPixelAlpha(
       ufoRaster raster_instance,
       int x,
       int y,
       double* a);

ufoRasterGetPixelAlpha returns the Alpha value for a pixel.

Values are normalized in the range (0..1).

Depending on the raster, the values returned are as follows:

ufoRasterGetPixelAlpha

• Called on an RGB raster returns a = (R+G+B)/3

• Called on an A raster returns a = A

• Called on an RGBA raster returns a = A
