Hi,

I've checked the reference already but I've not seen something like a vector filling function. Just the basic shapes.

What I'm looking for are functions like those I know from AS3.

i.e.:

this.beginFill(0x000000,1); //starts a fill with black at 100% opacity
this.moveTo(0,0); // sets the pointer to 0,0

// this fills a 10px square with black
this.lineTo(10,0);
this.lineTo(10,10);
this.lineTo(0,10);
this.lineTo(0,0);

this.endFill(); // ends the filling

This little function would give me a 10px vector square shape.

How do I do something like this in Processing?

Thanks

Hi,
I want to use an array instead of an ArrayList, but I'm not sure if I got the manual right. Is it right that I must define the arrays number of elements in advance?

In the case of my script I know the maximum number of possible elements that could emerge. But I'm not sure if they will. So is it possible to set an arrays size to the maximum number of possible elements and if the array is not filled completly to trim it down to it's real size?

( Or: How can I resize an array on runtime? )

Thanks!

Hi,

I'm new to Processing, so I hope this goes to the right board.

I'm adding pixels from an image array to an arrayList called pixel. My purpose is to sort all the pixels in a special way. After I've ensured where to place them in the img.pixels array I'm storring them in a arrayList called pixel  (just because Processing doesn't seem to perform basic array operations like pop, push, slice, etc.).

pixel.add(where, img.pixels[x]);

First Question: Is it a problem if I leave some positions in the arrayList void? i.e.: [0] = 1, [1]= nothing in here, [2]=3 ... and so on... because the values don't come in a correct order from 0 to n. Processing isn't complaining about it, but I'm not sure.

I'm trying to apply the arrayList pixel  to the pixels array of my image. But neither the arraylist.toarray method nor img.pixels[x] = pixel.get(x); works. It tells me that I cant assign an object to an integer, which sounds logical to me.

Second Question: How do I convert a Object delivered by the get() Method into an integer?

Thanks!
