What is image size limit?

Hi! I'm trying to work with very large image: 9083x9043 px, and getting error:

@imagemagick_magick-wasm.js?v=9eaa4f2f:5322 Uncaught (in promise) Error: UnexpectedEndOfFile '': No such file or directory @ error/rgb.c/ReadRGBImage/249

Handling smaller images works fine.

Is there any known limit on image size?

It might be possible that you are running into memory limits because the wasm binary that we create with emscripten is x86. There is an experimental flag in emscripten that can be used to enable a x64 wasm but I haven't tested with that. I will probably investigate that next year.

Ok, i see. Thanks for replying!

I also found this: https://emsettings.surma.technology/#MAXIMUM_MEMORY. I could probably increase the limit to 4GB for now.
