Is there an easy way to split a square into tiles?

in General Discussion • Other • 7 months ago

Hi all, I am new to Processing,
I would like to know if there is an easy way (maybe includes for loops?) to take on a square say 900*900 and split it into 9 equal tiles so it becomes a 3 by 3 grid?
I know I can do it manually by specifying the coordinates but any alternatives?
Thank you

By square you mean an rectangular image? How do you want to store that grid?

Yes rect(x,y,z,z) where z=width which would give a square. Sorry, I am not sure what you mean by"How do you want to store that grid"... could you clarify?

Starting a new thread for a new question is ok, but please don't doublepost the same question.

Here is a custom drawGrid method that conveniently let's you create a black and white grid by setting the top left starting position (startX, startY), the width of the whole grid (gridWidth, gridHeight) and the dimensions of the grid (dimX, dimY). All settings are separately customizable for the vertical and the horizontal axis.

Code Example

void setup() {
size(1000, 1000);
}
void draw() {
background(200);
drawGrid(50, 50, 900, 900, 3, 3);
}
void drawGrid(float startX, float startY, float gridWidth, float gridHeight, float dimX, float dimY) {
float w = gridWidth / dimX;
float h = gridHeight / dimY;
noStroke();
for (int y=0; y<dimY; y++) {
for (int x=0; x<dimX; x++) {
float xPos = startX + x * w;
float yPos = startY + y * h;
fill((x+y)%2==0?255:0);
rect(xPos, yPos, w, h);
}
}
}

Thank you for the tip and I will go ahead and remove the other question as you have pointed out for me :)

I noticed you removed every thread you ever started, but that is not what said at all. Let me clarify...

DO try to keep the same, very similar or closely related questions in one thread
DO open a new thread when the question is different from previous questions

DO NOT post the same question to multiple threads
DO NOT delete threads with answers

I removed your other thread because it was a doublepost of this question, which already had answers. As said above, you should never delete threads with answers, so I have restored a few of those threads. I hope this clarifies it.
