Description

The jit.resamp object spatially resamples the input matrix. This can be used to scale (zoom in/out) and offset (move) an image horizontally, vertically, or in both directions.

Attributes

Name Type g/s Description
interp_x int X value interpolation flag (default = 0) When the flag is set, values are interpolated across the x (horizontal) dimension values.
interp_y int Y value interpolation flag (default = 0) When the flag is set, values are interpolated across the y (vertical) dimension values.
wrap int Value wrap flag (default = 0) When the flag is set, values that exceed the limits are wrapped around to the opposite limit with a modulo operation. (1.1 wraps to .1, 1.2 wraps to .2, and -1.1 wraps to .9, -1.2 wraps to .8, etc.)
xscale float The scaling factor for the x (horizontal) dimension (default = 1.)
xshift float The shift (offset) amount for x (horizontal) dimension values (default = 0.). Positive values shift right, negative values shift left.
yscale float The scaling factor for the y (vertical) dimension (default = 1.)
yshift float The shift (offset) amount for the y (vertical) dimension values (default = 0.) Positive values shift down, negative values shift up.
