Hi! I’ve written a sketch that loads one PImage then slices this image into 16 equal (200px x 200px) “slices”. I have then created an array of PImage “slices” with 16 slots. I have written a for loop to look through the array and display a slice from the array at (0, 0).
What I would like to do: Be able to display all the “slices” at their .get locations. E.g for slice[9] it would be displayed at (x:200, y:400) of the sketch canvas.
The overall aim: Is to be able to split my PImage img (800px x 800px) into smaller (200px x 200px) “slices” displayed in a 4x4 grid format, at their appropriate locations - so I can control each “slice” independently.
I can’t figure out how to display the PImage array elements at their .get locations, any advice on how to go about this would be greatly appreciated - thanks!
This is my code currently:
// creating a 4 x 4 grid
int numColumns = 4;
int numRows = 4;
//creating a PImage array of "slices" with 16 slots
PImage img;
PImage[] slice = new PImage[16];
// setting the value of x and y
// need to make these two variables increment (possibly)
float x = 0;
float y = 0;
void setup()
{
size(800, 800);
//loading the main image
img = loadImage("img.png");
// assign the slots in the array with pixels from the image
// could try with copy() also set more arguments
slice[0] = img.get(0, 0, 200, 200);
slice[1] = img.get(200, 0, 200, 200);
slice[2] = img.get(400, 0, 200, 200);
slice[3] = img.get(600, 0, 200, 200);
slice[4] = img.get(0, 200, 200, 200);
slice[5] = img.get(200, 200, 200, 200);
slice[6] = img.get(400, 200, 200, 200);
slice[7] = img.get(600, 200, 200, 200);
slice[8] = img.get(0, 400, 200, 200);
slice[9] = img.get(200, 400, 200, 200);
slice[10] = img.get(400, 400, 200, 200);
slice[11] = img.get(600, 400, 200, 200);
slice[12] = img.get(0, 600, 200, 200);
slice[13] = img.get(200, 600, 200, 200);
slice[14] = img.get(400, 600, 200, 200);
slice[15] = img.get(600, 600, 200, 200);
}
void draw()
{
background(0);
//looking through all the images in the array
for (int i = 0; i < slice.length; i++)
//drawing the current "slice" at x and y
{
image(slice[9], x, y);
}
noFill();
stroke(255);
strokeWeight(2);
rect(x, y, 200, 200);
}
