ENVIGLTRasterSpatialRef::ConvertFileToFile

ENVIGLTRasterSpatialRef::ConvertFileToFile

The ConvertFileToFile method converts a set of pixel (x,y) coordinates in one Geographic Lookup Table (GLT) spatial reference to the same pixel location in another GLT spatial reference.

Syntax


ENVIGLTRasterSpatialRef.ConvertFileToFile, File1X, File1Y, File2X, File2Y, SpatialRef2 [, ERROR=value]

Arguments


File1X

The file x-coordinate in the first spatial reference. You can specify a scalar or a vector of File1X values; if it is a vector, the File1Y argument should also be a vector with the same number of elements:

File1X = [688.0, 641.1]
File1Y = [301.0, 280.0]

File1Y

The file y-coordinate in the second spatial reference

File 2X

A named variable that will contain the file x-coordinate in the second spatial reference

File2Y

A named variable that will contain the file y-coordinate in the second spatial reference

SpatialRef2

A reference to an ENVIGLTSpatialRefStandard object in the second spatial reference

Keywords


ERROR

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
