Crashes when decoding JPGs w/ sRGB IEC61966-2.1 color profile

[bvandenbos]

At least the color profile seems to be the consistent factor. May also be true for other profiles. I can decode JPGs w/out a profile just fine.

Stack trace:

Same issue here

[gchudnov]

@dalisoft do you have another example for an image?

[dalisoft]

I used PNG from here

Steps do this: If you have macOS, then you can do this by:

1. Open any image with macOS built-in photo viewer
2. Export image and select JPEG (select quality to High)

If you using Windows:

1. Open any PNG image with Adobe Photoshop (you can use free trial if haven't purchased)
2. After opening dialog will be be opened to select which color profile
3. Select sRGB (... no matter specs number)

I also ran into this issue. This was an issue with the underlying jpgJS library: https://github.com/notmasteryet/jpgjs/issues/34 However, they seemed to have fixed it here: https://github.com/notmasteryet/jpgjs/pull/36 I solved the problem by just using the current version of jpgjs directly rather than Inkjet, but I suspect this library could be fixed by simply updating the jpg.js file to a more current version.

today started upgrading all underlying libraries, but might take some time..

[gchudnov]

preliminary fix is here: https://github.com/gchudnov/inkjet/pull/7 released as 3.0.0-rc0.

if used in node.js: require('inkjet').default should be used. will revert back to require('inkjet') in rc1.
