tPixel(50, 42, pix2) changes color to white Logo.getPixel(0, 0) is the pixel (255, 255, 255, 255)Ĭopies RGBA values from given pixel into pixel at given (x,y) coordinate Returns pixel in this image at coordinate ( x, y)
Let input = document.getElementById("fileLoader") Īssuming user selected that image from their computer It is 100 pixels wide and 85 pixels tall.Ĭreates SimpleImage to represent image given in filenameĬreates SimpleImage whose dimensions are width by height.Īll pixels in this image are black (0, 0, 0, 255)Ĭreates SimpleImage to represent image user selected using the tAllFrom(pix1) changes color of pix2 to (0, 26, 87, 255)įor these examples, assume the variable logo has the value of the image "devil.png" below. tAlpha(100) changes color to (0, 26, 87, 100)Ĭhanges the value of all pixel components (its red, green, blue, and alpha) to match otherPixel's values tBlue(255) changes color to (0, 26, 255, 255)Ĭhanges pixel's alpha, or transparency, component to newA (if newA is not in range of 0-255 it is clamped to be in that range) tGreen(255) changes color to (0, 255, 87, 255)Ĭhanges pixel's blue component to newB (if newB is not in range of 0-255 it is clamped to be in that range) tRed(255) changes color to (255, 26, 87, 255)Ĭhanges pixel's green component to newG (if newG is not in range of 0-255 it is clamped to be in that range) Returns pixel's alpha, or transparency, component (always in range 0-255)Ĭhanges pixel's red component to newR (if newR is not in range of 0-255 it is clamped to be in that range) Returns pixel's blue component (always in range 0-255) Returns pixel's green component (always in range 0-255) Returns pixel's red component (always in range 0-255) Returns pixel's y-coordinate within image Returns pixel's x-coordinate within image pix2 is a pixel at coordinate (300, 400) representing the color white, with RGBA values of (255, 255, 255, 255).pix1 is a pixel at coordinate (100, 200) representing the color Duke blue, with RGBA values of (0, 26, 87, 255).
