I would like to add a mask to the images in this array, but I've run into an error that I can't resolve. Does anyone know how to do this? The array works, just not the masking part.

What I would like to do is to assign the same mask to cover each image in the array.

Here is my code:

int multiplyNum;
int row;
int count;

PImage[] page;
PImage maskArray;

void setup() {
  size(4000, 1000);
  background(0);

  page = new PImage[12];
  multiplyNum = 150;
  row = 17;
  count = 0;

  maskArray = loadImage("mask1.jpg");
 
  //Load Images in Memory
  for (int i=0; i<page.length; i++) {
    page[i] = loadImage(i +".jpg");
  }
 
  noLoop();
}

void draw() {

    for (int k=0; k<row; k++) {
      page.mask(maskArray);
      image(page[count], (k*multiplyNum), 1);
      count++;
      if(count%page.length ==0)count=0;
    }
  }
