hi,

Im loading an array of images, but I want to go trough a large number of images, 110,

the problem is that if my array have more than 12 elements I get a memory error,

I dont want just to increase the memory available, as I know im doing this in a non optimal way,

so how can I refactor my array?, or what to do to show my image gallery?

thanks,

please find the code here:

PImage [] images = new PImage[10]; //more than 12 images out of memory!!
int imageCount = 1;
void setup ()
{
size(displayWidth,displayHeight);
for (int i = 1 ; i<images.length; i++)
{
images[i] = loadImage("/images/"+i+".jpg");
}
}
void draw ()
{
background (0);
if (imageCount == 0) {
imageCount = images.length-1;
}
if (imageCount == images.length) {
imageCount = 1;
}
println ("my image count is on::"+imageCount);
image (images[imageCount], (displayWidth - images[imageCount].width)/2, (displayHeight - images[imageCount].height)/2);
}
void keyPressed()
{
if (key == CODED) {
if (keyCode == UP) {
println("up");
imageCount++;
}
if (keyCode == DOWN) {
println("DOWN");
imageCount--;
}
if (keyCode == RIGHT) {
println("RIGHT");
}
if (keyCode == LEFT) {
println("LEFT");
}
}
}

What are the sizes of your image ? (remember your image are unpacked after loading so a 1024*1024 image would take 4 Megs of Ram)

However may be you should try to dynamically load the previous N and next N images + the current one and destroy the others in an Arraylist ? (I hope you see what I mean)

As said...
You can also try and put g.removeCache( images[imageCount]); after the image() call. It will reduce the memory usage, perhaps at the cost of a small slowdown. (If you use 2.0b, at least.)
