Name | ### pixels[]
Examples |
    color pink = color(255, 102, 204);
    loadPixels();
    for (int i = 0; i < (width*height/2)-width/2; i++) {
      pixels[i] = pink;
    }
    updatePixels();
Description | Array containing the values for all the pixels in the display window. These values are of the color datatype. This array is the size of the display window. For example, if the image is 100x100 pixels, there will be 10000 values and if the window is 200x300 pixels, there will be 60000 values. The index value defines the position of a value within the array. For example, the statment color b = pixels[230] will set the variable b to be equal to the value at that location in the array. Before accessing this array, the data must loaded with the loadPixels() function. After the array data has been modified, the updatePixels() function must be run to update the changes. Without loadPixels(), running the code may (or will in future releases) result in a NullPointerException.
Syntax |
    pixels[index]
Parameters |
index | int: must not exceed the size of the array
