Class PImage got a public field called format, in which we can assign constant ARGB to it:

processing/processing/blob/master/core/src/processing/core/PImage.java#L69


      
          * @see PApplet#imageMode(int)
          * @see PApplet#createImage(int, int, int)
          */
          public class PImage implements PConstants, Cloneable {
          
           /**
            * Format for this image, one of RGB, ARGB or ALPHA.
            * note that RGB images still require 0xff in the high byte
            * because of how they'll be manipulated by other functions
            */
           public int format;
          
           /**
            * ( begin auto-generated from pixels.xml )

            * 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 <b>index</b> value defines the position of a value within
            * the array. For example, the statement <b>color b = pixels[230]</b> will
