ENVI_EVF_DEFINE_CLOSE

ENVI_EVF_DEFINE_CLOSE

Use this function to finish defining a new EVF. You must call this function before you can use the new EVF. For convenience, it optionally returns the ID of the new EVF. You must initialize the EVF using ENVI_EVF_DEFINE_INIT.

Syntax


Result = ENVI_EVF_DEFINE_CLOSE(EVF_PTR [, /RETURN_ID])

Arguments


EVF_PTR

This is a pointer to the new EVF, and it is returned from ENVI_EVF_DEFINE_INIT.

Keywords


RETURN_ID (optional)

Set this keyword to return the ID of the new EVF. This keyword saves you the step of opening the new EVF using ENVI_EVF_OPEN.

Example


See the code example under ENVI_EVF_CLOSE.
