Optimisation for thumbnail

[bubbatls]

There is no need to rebuild a data uri.
We can use URL.createObjectURL and a Blob.
It is faster, and further use of the URL will be too.

Thanks @bubbatls
Could you update your pull request so it passes the linter rules?

[bubbatls]

Sorry, I've worked too fast and so... too dirty.
It's done

[blueimp]

Thanks again. :)

[bubbatls]

maybe the code for building data-uri might be used in loadImage.createObjectURL when it is detected it does not work properly

[blueimp]

Could you clarify what you meany by "it does not work properly"?

[bubbatls]

The variable urlAPI might be undefined if it is not available or buggy (for opera 12 as I saw in comments)
And the data-uri might solve the issue, but maybe it is a bad idea to potentielly use it for something bigger than a thumbnail

[blueimp]

The EXIF code is only called in browsers that do support DataView.
Opera 12 is an edge case, but I don't think this browser is even supported anymore.
There's still Safari 6 (and potentially other browsers using webkitURL), but that is solved by using loadImage.createObjectURL.

Thanks for the explanation,
And thanks for this project
