Hi,

I got a problem on this line:
   PImage imgCell[i] = imgSource.get(0, 0, cellWidth, cellHeight); // Assign

If I dont use the for loop but just use:
 //PImage imgCell0 = imgSource.get(0, 0, cellWidth, cellHeight); // Assign
then it runs fine (unless I place that in the for loop).

I get, syntax error, maybe missing semicollon

What did i do wrong?

Code:

PImage imgSource;
PImage[] imgCell; // Declare
int cellWidth = 32;
int cellHeight = 32;
int cells; //total ammount of cells
int rows, columns;


void setup(){
  size(500, 500);

  imgSource = loadImage("test.png");
  columns = imgSource.width/cellWidth;
  rows = imgSource.height/cellHeight;
  cells = rows*columns;
  imgCell = new PImage[cells]; // Create

  noLoop();
}

void draw(){
  
  for(int i=0; i<columns; i++){
    PImage imgCell[i] = imgSource.get(0, 0, cellWidth, cellHeight); // Assign
  }
  
  
  //PImage imgCell0 = imgSource.get(0, 0, cellWidth, cellHeight); // Assign
  //PImage imgCell1 = imgSource.get(32, 0, cellWidth, cellHeight); // Assign
  //PImage imgCell2 = imgSource.get(64, 0, cellWidth, cellHeight); // Assign
  
  
  image(imgCell0, 0, 0);
  //image(imgCell1, 32, 0);
  //image(imgCell2, 64, 0);

} 

I don't follow you, must I place that code inside setup instand of draw?

Then i get the error on the last line,   image(imgCell0, 0, 0);:

can not find anything named "imgCell0"

If i place the for loop inside setup then the error is the same.

Code:

PImage imgSource;
PImage[] imgCell; // Declare
int cellWidth = 32;
int cellHeight = 32;
int cells; //total ammount of cells
int rows, columns;


void setup(){
  size(500, 500);

  imgSource = loadImage("test.png");
  columns = imgSource.width/cellWidth;
  rows = imgSource.height/cellHeight;
  cells = rows*columns;
  imgCell = new PImage[cells]; // Create

  noLoop();
}

void draw(){

  for(int i=0; i<columns; i++){
    // PImage imgCell[i] = imgSource.get(i*cellWidth, 0, cellWidth, cellHeight); // Assign
    imgCell[i] = imgSource.get(0, 0, cellWidth, cellHeight); 
  }

 // PImage imgCell0 = imgSource.get(0, 0, cellWidth, cellHeight); // Assign
  //PImage imgCell1 = imgSource.get(32, 0, cellWidth, cellHeight); // Assign
  //PImage imgCell2 = imgSource.get(64, 0, cellWidth, cellHeight); // Assign

  println("imgCell0 "+imgCell[0]);


  image(imgCell0, 0, 0);
  //image(imgCell1, 32, 0);
  //image(imgCell2, 64, 0);
} 

here's the image i use

Quote:


but there are more imgCell(s) right,

imgCell0, imgCell1, imgCell3 etc.

what I try to do is break up the picture in rows and columns where every cell is it's own image. This to give every cell the average color.
