I have noticed that VintageJS dont works well on big file sizes. Is there any solution? WebGL?

vintageJS is not designed to work on HiRes images. The algorithm runs on your JavaScript Engine and and has to manipulate/recalculate (imageHeight_imageWidth_3(rgb)) values. If you do the math you see that it gets messy for big images.
If you have an idea to implement high performance calculation for big images that'd be great.

One way would be to outsource the calculation of the effect into a webworker (support seems to be okay). That does not speed up anything but the UI is not blocked during the calculation of the effect.
Downside:
- New js-file -> new http-reuqest
- Webworker has no window or document objects which means it only suites for doing the pure math for any imageData Object
