Functions

_translate(a, dx, dy, output=None, mode='nearest', cval=0.0)
_translate does positive sub-pixel shifts using bilinear interpolation. source code

translate(a, sdx, sdy, output=None, mode='nearest', cval=0.0)
translate performs a translation of 'a' by (sdx, sdy) storing the result in 'output'. source code

translate(a, sdx, sdy, output=None, mode=`'nearest'`, cval=0.0)

source code

translate performs a translation of 'a' by (sdx, sdy)
storing the result in 'output'.

sdx, sdy  are float values.

supported 'mode's include:
    'nearest'   elements beyond boundary come from nearest edge pixel.
    'wrap'      elements beyond boundary come from the opposite array edge.
    'reflect'   elements beyond boundary come from reflection on same array edge.
    'constant'  elements beyond boundary are set to 'cval'
