Memory Leak: What am I doing wrong? (Read 522 times)

Stever1975 YaBB Newbies Offline Posts: 8	Memory Leak: What am I doing wrong? Apr 15^th, 2010, 8:41am http://www.stever.cc/FromScratch/applet/ Granted I could try to increase memory size. But I have a feeling I'm not cleaning up somewhere I should be. The reason I think it's a leak is that it takes a few seconds to happen. Steve

Generic note: always call size() first in setup(). Code before size() is often called twice...

The design of the code is strange... did you wrote it to illustrate your problem or is that the end result you wanted to get?

The problem is that you can create a new PImage 60 times per second... Of course, all the previously created buffers should be garbage collected, but perhaps it can't act quick enough to clean up the memory.

The image being of fixed size, you can create the buffer in setup() and reuse it on each call.
Or just avoid to call blend_new() in draw(), but again it depends on your final objective.

Thanks
Creating the buffer in the setup worked.
Interesting thought about garbage collection not being able to keep up. I'll have to keep that in mind. Because the way I'd like this to work is to keep returning PImage like so:
d1=fade(d1);
d1=blur(d1);
d1=stretch(d1);
image(d1,0,0);

Similar to chaining in JQuery.

All this would be kept in the draw function and change based on frame rate

This code is a little weird. I am sort of playing around.
So unsure of my final objective. I think I want to make a graphics library that can help in creating animated poetry.
