Args |
x | 3D numpy array - a 2D image with one or more channels. |
theta | Rotation angle in degrees. |
tx | Width shift. |
ty | Heigh shift. |
shear | Shear angle in degrees. |
zx | Zoom in x direction. |
zy | Zoom in y direction |
row_axis | Index of axis for rows (aka Y axis) in the input image. Direction: left to right. |
col_axis | Index of axis for columns (aka X axis) in the input image. Direction: top to bottom. |
channel_axis | Index of axis for channels in the input image. |
fill_mode | Points outside the boundaries of the input are filled according to the given mode (one of {'constant', 'nearest', 'reflect', 'wrap'} ). |
cval | Value used for points outside the boundaries of the input if mode='constant' . |
order | int, order of interpolation |
Returns |
The transformed version of the input. |
Raises |
ImportError | if SciPy is not available. |
