Multiple threads from one file?

That should work.

[Astusvis]

Is there a limit to the number of threads? Or a number I *shouldn't* exceed?

[bartbes]

The limit depends on the running system, and is generally huge.
However, you should try keeping around as little threads as possible, because it's both wasteful to have them around and not use them, and synchronization etc will only have a negative effect.
Of course true parallel execution can only happen when the amount of threads is less than or equal to the amount of processor cores.

OK, now my having multiple threads make those threads corrupt the imagedata they are making >.>
Can anyone make sense of why?

[Boolsheet]

ImageData manipulation is not thread safe in 0.7.2. It's fixed in 0.8.0.
You could save the pixel values to a table, generate a string with table.concat and push that to the other thread.

If you haven't seen the warning on Thread:kill yet, there's really no reason you should use it.
It disregards everything and terminates the thread. This is useless unless you have an emergency situation where the process has to stop immediately.

[Astusvis]

Ok, I'll do that.
And yes I have seen the warnings, but for some reason I can't restart a thread without manually killing it first. I disregarded the warning since I am only killing it once it has finished.

I disregarded the warning since I .....

Famous last words.

[Astusvis]

Sorry, do you have a problem with logic?

for some reason I can't restart a thread without manually killing it first.

Why would you want to restart a thread anyway? Can't you put the bulk of the code in a big loop instead?

I disregarded the warning since I am only killing it once it has finished.

I'm not sure about the actual implementation details, but that might still cause problems with things not having a chance to be cleaned up properly.
