ImageData:mapPixel Transform an image by applying a function to every pixel. This function is a higher order function. It takes another function as a parameter, and calls it once for each pixel in the ImageData. The passed function is called with six parameters for each pixel in turn. The parameters are numbers that represent the x and y coordinates of the pixel and its red, green, blue and alpha values. The function should return the new red, green, blue, and alpha values for that pixel. fu

ImageData:getWidth Gets the width of the ImageData in pixels. Function Synopsis width = ImageData:getWidth( ) Arguments None. Returns number width The width of the ImageData in pixels. See Also ImageData

ImageData:getString Removed in LÖVE 0.9.0 It has been moved to Data:getString. Gets the full ImageData as a string. Function Synopsis pixels = ImageData:getString( ) Arguments None. Returns string pixels The raw data. See Also ImageData

ImageData:getPixel Gets the color of a pixel at a specific position in the image. Valid x and y values start at 0 and go up to image width and height minus 1. Non-integer values are floored. Prior to 0.10.2, this function does not properly handle non-integer coordinates, and may produce an invalid result when non-integer values are passed. Function Synopsis r, g, b, a = ImageData:getPixel( x, y ) Arguments number x The position of the pixel on the x-axis. number y The position of the pixel

ImageData:getHeight Gets the height of the ImageData in pixels. Function Synopsis height = ImageData:getHeight( ) Arguments None. Returns number height The height of the ImageData in pixels. See Also ImageData
