imregrid – regrid an image onto a template image – analysis task

Description

Imregrid will regrid an input image onto a new coordinate system from a template image or to a new directional reference frame. If a template image is used, then the input and template images must have the same coordinate structure.

Parameters

Parameter Explanations

imagename

''

Name of the source image

template

'get'

A dictionary, refcode, or name of an image that provides the output shape and coordinate system

output

''

Name for the regridded image

asvelocity

True

Regrid spectral axis in velocity space rather than frequency space?

axes

numpy.array( [ ] )

The pixel axes to regrid. -1 => all.

shape

numpy.array( [ ] )

Shape of the output image. Only used if template is an image. If not specified (-1), the output image shape will be the same as the template image shape along the axes that are regridded and the same as input image shape along the axes which are not regridded.

interpolation

'linear'

The interpolation method. One of “nearest”, “linear”, “cubic”.

decimate

int(10)

Decimation factor for coordinate grid computation

replicate

False

Replicate image rather than regrid?

overwrite

False

Overwrite (unprompted) pre-existing output file?
