Hi,

I created a simple sketch that loads 30 jpeg images into a PImage array and then loops through them. Each jpeg is around 170Kb and I am running WinXP in a 3.2GHz P4 and have 1Gb RAM.

QUESTION 1)
Some frames after the loop starts I get this error: "Exception in thread "Thread-2" java.lang.OutOfMemoryError: Java heap space". If I lower the number of image to 15 then everything works fine. Using OPENGL the problem remains. What am I doing wrong here?

QUESTION 2)
Loading the 30 images takes quite a long time (around 4 or 5 seconds) considering it is such a simple thing. Why is it taking so long?

Note: pictures names are like this: Barbara0001.jpg, Barbara0002.jpg, Barbara0003.jpg, etc...

Here's the sketch:

>>>> BEGIN OF CODE >>>>>>>>>>>>>>>>>>

///////////////////////////////////////////////
// globals
///////////////////////////////////////////////
int MAX_NUM_IMAGES = 30;
String IMAGE_FILENAME = "images/Barbara";
int count = -1;
PImage[] images;

///////////////////////////////////////////////
// setup
///////////////////////////////////////////////
void setup()
{
 // Environment setup
 size(600,600);
 framerate(6);

 // Load images
 images = new PImage[MAX_NUM_IMAGES];
 for(int i=0;i<MAX_NUM_IMAGES;i++)
 {
   String name = "000" + i+1;
   name = name.substring(name.length()-4);
   images[i] = loadImage(IMAGE_FILENAME + name + ".jpg");
   println("image " + name + " loaded");
 }
}

///////////////////////////////////////////////
// draw
///////////////////////////////////////////////
void draw()
{
 count++;
 image(images[count], 0, 0);
 if (count == MAX_NUM_IMAGES-1)
   count = -1;
}

<<<<<<< END OF CODE <<<<<<<<<<<<<<<<<<<<<

Thanks in advance,
Nuno

Thank you! Problem solved! No more memory error.

Pictures are still very slow to load. But although annoying, this doesn't stop me from continuing the project.
