Affine Transformations by click- and/or drag-actions:
- Near 0=MM but not 0=MM: Rotate
- RightClick 0=MM: ResetImage
- 0=MM: ResetShape (width 360)
- 2=TM: SkewX (= shearX)
- 4=MR: SkewY (= shearY)
- 6=BM: TrueHeight
- 8=ML: TrueWidth
- 1=TL,3=TR,5=BR,7=BL: TrueResize
  [True = preserves current shape.]
Hint. Fine tune rotating with the mouse by increasing the distance to the center while rotating.
RightClick switches temporarily the action of handles (2=TM,6=BM) and (4=MR,8=ML).
RightClick on handles (1=TL,3=TR,5=BR,7=BL) inverts the current proportional settings temporarily.
TrueWidth and TrueHeight resize proportionally (if property proportional is true).
Resizing (1=TL,3=TR,5=BR,7=BL) allows to flip horizontally or vertically, incl. handles!
Set/use (a lot of) properties in the tabs of property inspector (or by script):
- get the [property] of [widget]
- set the [property] of [widget] to [value]
The following messages are passed to LC Script so you can use it:
mouseEnter, mouseLeave and mouseUp.
After installation of the widget and restarting LiveCode find detailed help in the dictionary.
