Maximum call stack size exceeded on iOS Safari

[Steve Pieper]

(neat project! 👍 )

Things work great for me on desktop machines, but not on mobile (ios safari).

For example the rotate example results in the stack trace below.

It looks like magick-wasm doesn't have this issue and may work for me, so I'm going to explore that. I wouldn't have found that project without reading your issues so thanks for sharing your development in the open.

hrm... I should probably just go an upload a different version of wasm-imagemagick to fix the sample.

I do use compiled versions for the following pages that do work on mobile safari.
See https://knicknic.github.io/imagemagick/ (cool page that lets you create links to arbitrary imagemagick commands and save them). The page even works offline.

a website for splitting comics (why I made this library). https://knicknic.github.io/croppy/

As for JS libraries wrapping imagemagick, I would also recommend https://github.com/dlemstra/Magick.WASM .

Thanks for getting back to me. After some playing around I decided to just rebuild your project from scratch, and after making a few changes it ended up working well. We are using it for our chest X-ray experiments (see https://acil-bwh.github.io/slowdown-covid19).

Here are the changes I made to the build:

I also hacked up the magic.js to suit my needs. I know that's bad form, but I was a little tired of emscripten at that point and just wanted things to work : ). The edits are flagged with "COVICTORY" in comments.

Thanks again,
Steve

this seems to be working as of latest release, see https://knicknic.github.io/imagemagick/rotate/
