(https://i.imgur.com/0cuw31L.mp4) Here is a video of me reproducing the problem. I don't believe the bit depth was important. In the video, I first exported a smaller image. Afterwards, I exported a very very big image and it crashed. So, it seems the problem may have been the the size of the large pretty image.

(https://i.imgur.com/0O1xZij.mp4) Here is another video where I save as a `.ourpaint` file. It crashes just as well, however the file it wrote (`i_am_testing.ourpaint`) had 178 bytes of data in it after the crash.

When I recorded the first clip, I had about 50 gigabytes of RAM available out of 64 gigabytes. Upon export, Task Manager showed OurPaint using 15 gigabytes of RAM before the crash (do note that Task Manager may lag behind).

There were 90 gigabytes of space in the drive I attempted to export to.

Perhaps automatic backups would help ease users in situations such as this? (And if the backup itself causes the program to crash, at least it crashes early in a user's session)

Wow you are indeed trying to save a huge file (in the first video the terminal actually outputs the dimension, it’s like 20000px wide…) I’ll definitely check and try handle the case of huge dimensions. I don’t really think it’s a memory problem, it’s likely that some integers overflowed because I don’t think I have used 64 bit integer in some places that could be relevant.

(What kind of usages do you need that big of an image? XD you can see the zoom level at the bottom left of the canvas, and by default it’s 50%)

Anyways, thank you very much for your detailed feedback :D

(In my usage I made a few 3840x2160 paintings in one canvas, spaced apart)

Oh, then if you don’t need to export them as the “spaced apart” layout as-is, you can use the crop tool to specify a region to export. That way it shouldn’t crash. If you draw those images on different layers apart, each layer won’t be as big so you can succesfully save it.

The recent project I’ve been doing is sized at 10641x7730 and it works without any particular problem :D

Also in v0.3 there will going to be a layer moving feature so you can move individual pictures around granted you’ve painted them in separated layers.

I have fixed the huge file saving issue and it will be available in the next version. Now saving is only limited on how much memory your machine can allocate, and when it can’t allocate enough memory, it should give a prompt and not crash :D

Awesome :) Thank you, Yiming.
