coordsys.convertmany - Function

1.1.3 Convert many numeric mixed coordinates


Description

This function converts between many mixed pixel/world/abs/rel numeric coordinates. See function convert for more information.

The only diffference with that function is that you provide a matrix holding many coordinates to convert and a matrix of many converted coordinates is returned.

Arguments

Default:

true

dopplerin

Input doppler type for velocities

allowed:

string

Default:

radio

unitsin

Input units, string vector

allowed:

stringArray

Default:

Native

absout

Are output coordinate elements absolute ?

allowed:

boolArray

Default:

true

dopplerout

Output doppler type for velocities

allowed:

stringArray

Default:

Native

shape

Image shape, integer array

allowed:

intArray

Default:

-1

Returns
variant
