Memory issue with large images

[shcmack]

This script is pretty cool man! However, when trying to use this on large images (5000x4000 px) I get "Error code: Out of Memory" in the browser. I do have enough RAM, and I've tried with different browsers, so I'm not sure where the issue lies. The reason for the huge image-size is to get high resolution outputs. Is there any workaround for this?

Hi!
Thanks. Is there a stack trace with the error message?

[shcmack]

It doesn't output any, however it seems the reason for the crash is that all browsers have a memory limitation per tab (https://js9.si.edu/js9/help/memory.html). It might be possible to hack some workaround within the script, but that's above my skill level.

I think the memory limit may even be specific to something we are doing with the canvas element, since a 4GB tab limit seems easily enough even to work with a 5000x4000 bitmap.

Unfortunately I've not got time at the moment to dive into this - I wish I could spend time on these fun experiments but these days I'm spending all my time building stuff that might make money 😂
