panic: runtime error: slice bounds out of range

Hello,

I am trying to write an resized image and I am getting this panic:

panic: runtime error: slice bounds out of range [::-316]

I'm away from my laptop right now, but I have a good hunch about what might be causing the issue and will look into it tomorrow. In the meantime, could you let me know which package or code you used to resize the image? That way, I can test it directly when I get back. Thanks!

Hey, your response slipped through, sorry for that. Thank you very much for the fix! The generating library was muesli/smartcrop

No worries! Hopefully, it's fixed now. I recreated it with an image that doesn’t have bounds min at zero which resulted in the same panic error.
