Class PImage Name set() Examples PImage img = loadImage("tower.jpg"); color black = color(0, 0, 0); img.set(30, 20, black); img.set(85, 20, black); img.set(85, 75, black); img.set(30, 75, black); image(img, 0, 0); Description Changes the color of any pixel or writes an image directly into the image. The x and y parameter specify the pixel or the upper-left corner of the image. The color parameter specifies the color value.Setting the color of a single pixel with set(x, y) is easy, but not as fast as putting the data directly into pixels[]. The equivalent statement to "set(x, y, #000000)" using pixels[] is "pixels[y*width+x] = #000000". Processing requires calling loadPixels() to load the display window data into the pixels[] array before getting the values and calling updatePixels() to update the window. As of release 0149, this function ignores imageMode(). Syntax img.set(x, y, color) Parameters img PImage: any variable of type PImage x int: x-coordinate of the pixel or upper-left corner of the image y int: y-coordinate of the pixel or upper-left corner of the image color color: any value of the color datatype Returns None Usage Web & Application Related get()pixels[]copy()
