1.1.3.0 coordsys.convertmany

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


Inputs
coordin	Input coordinate, numeric matrix
	allowed:	any
	Default:	variant
absin	Are input coordinate elements absolute ?
	allowed:	boolArray
	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:	string
	Default:	radio
unitsout	Output units
	allowed:	stringArray
	Default:	Native
shape	Image shape, integer array
	allowed:	intArray
	Default:	-1

Returns
anyvariant
