void ufoRasterGetPixelColAlpha( ufoRaster raster_instance, int x, int y, double* r, double* g, double* b, double* a);
ufoRasterGetPixelColAlpha returns the RGB-Alpha values for a pixel.
Values are normalized in the range (0..1).
Depending on the raster, the values returned are as follows:
• Called on an RGB raster returns r=R, g=G, b=B, a=1
• Called on an A raster returns r=A, g=A, b=A, a=A
• Called on an RGBA raster returns r=R, g=G, b=B, a=A
