change of size after scale

nisabek

Hi,

I am a bit confused...what happens to the object when I call scale? I expected the size of that object to be changed, but e.g. in case of RiTa http://rednoise.org/rita/ library, after scaleTo function, the width of the text stays the same. But I can see the change if I get the size in the callback function and only there.

Now - is this RitaTExt specific behavior? Am I misunderstanding the whole scale concept ? in order to get the changes to the object elsewhere..do i need to manually change...the font of the text in the callback? :/ Feeling that I am doing smth wrong....

THanks for support!

Here I draw the same object twice (except the first time I draw it it is red, and the second time I draw it, it is green). The only difference is that I call scale in between drawing the two objects. This scales the positioning system used to place and size objects by some factor.

size(220,220);
background(0);
noStroke();
fill(255,0,0);
rect(10,10,100,100);
scale(.6);
fill(0,255,0);
rect(10,10,100,100);

If you understand why this sketch gives the output it does, then you understand the scale() function correctly.

ok, thanks! got it i guess :) the scale() scales the space and not a particular object.

resize() can also do the trick.
