applying different filters to a tiled image
Jan 5th, 2009, 9:17pm  
I have tiled and image and aplied an RGB filter to the image but i would like to have a different filter on each tile of the image.

my present code is

//image tile

size (650,450);
PImage img2 = loadImage("ketty.jpg");
tint (10,100,200);
int cols = 4;
int rows = 4;
int w = width/cols;
int h = height/rows;
for (int i =0; i<height; i+=h){
 for (int j=0; j<width; j+=w){
   image(img2, j, i, w, h);  
 }
}

Any suggestions how to change the RGB values for each tiled image?

thanks

You just have to call tint() before displaying each copy of the image. Example:
Code:
size(650, 450);
PImage img = loadImage("ketty.jpg");
int cols = 4;
int rows = 4;
int w = width/cols;
int h = height/rows;
for (int i =0; i<height; i+=h){
  for (int j=0; j<width; j+=w){
    tint(map(i, 0, height, 10, 255), map(j, 0, width, 10, 255), 128);
    image(img, j, i, w, h);  
  }
}
