Description
The filter ShearRegion applies basic affine transform to each regions's pixel.
Shear affine transform when X axis is selected:
\[ \left[\begin{array}{ccc} x' \\ y' \end{array} \right] = \left[\begin{array}{ccc} 1 & inShear \\ 0 & 1 \end{array} \right] \left[\begin{array}{ccc} x \\ y \end{array} \right] \]Shear affine transform when Y axis is selected:
\[ \left[\begin{array}{ccc} x' \\ y' \end{array} \right] = \left[\begin{array}{ccc} 1 & 0\\ inShear & 1 \end{array} \right] \left[\begin{array}{ccc} x \\ y \end{array} \right] \]Complexity Level
This filter is available on Advanced Complexity Level.
