| Description |
|
Changes the color of any pixel or writes an image directly into the display window. The x and y parameter specify the pixel to change and the color parameter specifies the color value. The color parameter is affected by the current color mode (the default is RGB values from 0 to 255). When setting an image, the x and y parameters define the coordinates for the upper-left corner of the image (the placement of the image is not affected by the imageMode() function).
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". The (BETA) version of 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. |
