[Interest] Camera cature ios roated 90 ccw (5.4.1)

[Gianluca]

Hello,
attached there is the code I used for rotating the image.
It comes from a commercial project, so I removed all parts cannot share.

The method that did the trick is scaleAndRotateImage, the rest of the code is for selecting an image or for taking an image using native iOS controllers instead of Qt provided ones.

I’m sorry but this code needs that you know objective-C, iOS SDK and how to integrate them into a Qt app.

Ciao,
Gianluca.
