This will happen occasionally while trying to detecting codes in wasm.

I made sure that my luma input was a square image and I am able to scan barcodes now. I have not encountered the error since.

I'll look into this. Do you happen to have any images that trigger the error?

[hschimke]

I have a potential solution, but it only addresses the error and not whatever root cause results in it happening. If you have an image that causes it you can safely upload to be added to the test suite that would be very helpful.

Alternatively, if your use-case is images that you do not want public and cannot share, I can provide a GitHub branch with the potential solution for you to test.

@dankirkham I bundled this, and a few other changes, into rxing 0.4.11, which is the backing version for the NPM package version 0.1.26. If you continue to see the issue please reach out.
