ENVI::OpenAnnotation

The OpenAnnotation function method creates a new ENVIAnnotationSet from a file.

Example

; Start the application

e = ENVI()

; Open an annotation file. Update this line as needed.

file = 'C:\MyFiles\Annotation.anz'

; Create an ENVIAnnotationSet

annotation = e.OpenAnnotation(file)

Syntax

Result = ENVI.OpenAnnotation(URI [, Keywords=value])

Return Value

This method returns a reference to an ENVIAnnotationSet object.

Arguments

URI

Specify a string with a fully qualified path to an ENVI annotation file (.anz).

Keywords

ERROR (optional)

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.
