- def getPixel(x: Int, y: Int): SurfaceIO[Option[Color]]
Gets the color from the this surface.
Gets the color from the this surface. This operation can be perfomance intensive, so it might be worthwile to either use
getPixelsto fetch multiple pixels at the same time or to implement this operation on the application code.- x
pixel x position
- y
pixel y position
- val getPixels: SurfaceIO[Vector[Array[Color]]]
Returns the pixels from this surface.
Returns the pixels from this surface. This operation can be perfomance intensive, so it might be worthwile to implement this operation on the application code.
