Fill image with pattern (different sizes depending on grayscale)

Hey :-)

i am trying to figure out the following: I want to load an image into processing and translate the grayscale / color values into a pattern of the same graphic (let's say a star). The result should be an image which is put together from stars in different sizes. I already played around with another processing code which does the same effect with dots (please find image attached) but i was not able to do this with let's say an svg. The code was way to complicated so i would be really grateful if someone could help me with the basics ...

thanks a lot,

tm

Hello : )

i am an absolute beginner and actually trying to achieve the following: My processing sketch should

load an image and display its color values and display the color in the left upper corner. This works

perfectly by but what i really want, is that the sketch begins reading in the upper left corner, proceeds

to the upper right corner and then does the same thing with the next line and so on. (For better understanding:

The image consists of 8x8 color swatches which are 50 x 50 px each). I am not good at programming and i was

not able to code the loops i need for this. I would be really grateful if you can help me with this idea.

Below the code i have done so far (with parts of the first loop which i was not able to finish)
2. PImage Bilddatei;
4. void setup() {
5. size(400, 400);
6. Bilddatei = loadImage("400x400grid.jpg");
7. image(Bilddatei, 0, 0);
8. }
10. void draw() {
11. int positionX=320;
12. int positionY=50;
13. float y=0;
14. // var anlegen
15. while (y <= 400) {
16. color Quadrat = Bilddatei.get(positionX,positionY);
17. fill(Quadrat);
18. rect(0,0, 100, 100);
19. y = y + 20;
20. }
21. }
Thank you so much! tm

Hello : )

i just started with processing and i am excited about all the new possibilities :-) i was playing around with "open" and able to launch a mac application with this command. Now i am wondering, if i also can close/quit a application via processing?

thanks a lot,

tm
