QR-Reader_v101
### v1.0.0 ... Aug 13, 2019 ... first version on "Sample Stacks"
### v1.0.1 ... Aug 14, 2019 ... workarounds for linux (snapshot), drag improved

QR-Reader runs with any edition of LC 8/9 (tested with 9.5/9.0.4/8.1.10) on every platform that supports the browser widget **(see below)

It is a QR code *reader* which reads from static images that may be slightly rotated/skewed/distorted.

You can make it to a QR code *scanner* by providing webCam/mobileCam camera snapshots to read from. Usually images from cameras that can't autofocus or focus manually are not good enough for that.

The stacks uses the excellent JS library jsQR ( https://github.com/cozmo/jsQR ) and is by that Apache2-licensed.

On linux tested with 9.0.5 or 8.1.10 on Ubuntu/xUbuntu1604 64bit
using http://forums.livecode.com/viewtopic.php?p=153351#p153351

(**) This works now with images ("nots" are LC bugs) in the sample stack:

Mac: CA, CB, DA. But not DB.
Win: CA, DA. But not CB and DB.
linux: CA. But not DA, CB and DB.

CA = Copy/Paste from other apps
CB = Copy/Paste from browser widget (rightClick)
DA = Drag from other apps
DB = Drag from browser widget
Ajax Loader
