problem applying mask to image array
Jul 23rd, 2008, 6:42pm  
I'm trying to apply a mask to all images in an array. I've looked for help in the discussion and the closest thing I could find was this:
http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Syntax;action=display;num=1197253210;start=0#0
which didn't help me out.

I'm pretty sure I'm naming the array incorrectly when I'm trying to draw my mask:
images[].mask(maskImg);

Here's the full code:
int xpos;
int xpos;
int ypos;
int xWidth;
int yHeight;
int count = 0;
int numImages = 87;
PImage[] images = new PImage[numImages];
PImage maskImg;

void setup() {
 size(1450, 500);
 background(0);
 frameRate(3);
 xpos = 1450;
 ypos = 10;
 for (int i = 1; i <= images.length; i++) {
   images[i-1] = loadImage("B (" + i + ").jpg");
 }
 maskImg = loadImage("Jamaica_51.jpg");
}

void draw() {
 images[].mask(maskImg); //draws the mask
 if (count < images.length) {
   tint(225, 225, 225, createTint());
   image(images[count], xpos, ypos);
   count++;
 }
 for (int j = distanceBtwnImages(); j <= distanceBtwnImages(); j++) {
   xpos = xpos - j;
 }
}

int createTint(){
 int numberIs;
 numberIs = 50;
 return numberIs;
}

int distanceBtwnImages(){
 int numberIs;
 numberIs = 35;
 return numberIs;
}

You have to mask each image seperately:

Code:
PImage[] images = new PImage[numImages];
PImage maskImg;
 
void setup() {
  size(1450, 500);
  background(0);
  frameRate(3);
  xpos = 1450;
  ypos = 10;
  maskImg = loadImage("Jamaica_51.jpg");

  for (int i = 1; i <= images.length; i++) {
    images[i-1] = loadImage("B (" + i + ").jpg");  
    images[i-1].mask(maskImg);
  }
}
