The canvas2d dataURL-methods (and LC's base64-methods) are so far optimized that it is even slower if one directly sends and receives arrays, I tried it. There could be more gain (what would give a speed-up-factor of up to 500) by using webGL, but this has issues with some 'black-listed' graphic

Speed comparison with imageData 1920x1080

Here is a stack that compares simple grayLevel- and invert-filter for an image of size 1920x1080, needs LC 8 or 9. It shows the power of this "external" we have via LC Builder/the browser widget. go stack url ("http://hh.on-rev.com/xstacks/speedComparison.livecode;) or download the file

Re: How do we access the clipboard on mobile devices?

LC is a perfect tool, for me also plays the role of a GUI when seeking for speed. Javascript/HTML5 does a lot of low level binary data processing up to 100 times faster than LC Script (and no js-package needed for that). To use javascript/HTML5 is not "bypassing" the LC language" but *extending*
