19 Oct 2009	Image 2D Transformations Image 2D Transformations Translation Rotation Scaling	Jan Simon	No help, no H1-line, parameters are defined by INPUT, no checks of inputs, not vectorized, no pre-allocation of arrays (remarkably slow), inefficient (e.g. COS(Angle) is calculated for each single pixels in ROTATION), does not consider RGB images ([X x Y x 3] arrays ). ROTATION fails (indices out of range) but the algorithm is not a rotation at all. This is neiter a good for publishing on FEX nor a good homework.	1
