Literally no idea why it doesn’t work plz help

Code 
PImage ini;
PImage reo;
String[] log = {};
int[][] con = {
{-1,0,1},
{-1,0,1},
{-1,0,1}
};
int cropsize = 10;

void setup() {
  ini = loadImage("img.png");
  reo = ini;
  
  for ( int x = cropsize ; x < ini.width-cropsize ; x++ ) {
    for ( int y = cropsize ; y < ini.height-cropsize ; y++ ) {
      
      int r = 0;
      int g = 0;
      int b = 0;
      
      color c1 = ini.get(x-1,y-1);
      color c2 = ini.get(x-1,y);
      color c3 = ini.get(x-1,y+1);
      color c4 = ini.get(x,y-1);
      color c5 = ini.get(x,y);
      color c6 = ini.get(x,y+1);
      color c7 = ini.get(x+1,y-1);
      color c8 = ini.get(x+1,y);
      color c9 = ini.get(x+1,y+1);
      
      r+=int(red(c1*con[0][0]));

What happens and what do you want to happen instead?

Which lines are relevant for this?

You probably want to create a new PImage for reo and not link back to the same memory.
That’s just a wild shot at a problem I see might occur. I don’t know what you are trying to achieve either, so please answer to Chrisirs post if you still need help.

Getting the color of a single pixel with get(x, y) is easy, but not as fast as grabbing the data directly from pixels[] . The equivalent statement to get(x, y) using pixels[] is pixels[y*width+x] . See the reference for pixels[] for more information.
