Skew an input image.
Skew function skews the input array along dim0 by skew0 and along dim1 by skew1. The skew areguments are in radians. Skewing the data means the data remains parallel along 1 dimensions but the other dimensions gets moved along based on the angle. If both skew0 and skew1 are specified, then the data will be skewed along both directions.
Explicit output dimensions can be specified using odim0 and odim1.
All new values that do not map to a location of the input array are set to 0.
Skew is a special case of the af::transform function.
◆ af_skew()
C Interface for skewing an image.
-
Parameters
-
[out] out will contain the skewed image [in] in is input image [in] skew0 is amount by which the first dimension is skewed [in] skew1 is amount by which the second dimension is skewed [in] odim0 is the first output dimension [in] odim1 is the second output dimension [in] inverse if true applies inverse transform, if false applies forward transoform [in] method is the interpolation type (Nearest by default)
-
Returns
-
AF_SUCCESS if the color transformation is successful, otherwise an appropriate error code is returned.
