This routine has been replaced with the following methods: ENVI::OpenRaster, ENVI::OpenROI, and ENVI::OpenVector.

Use this procedure to open an ENVI Classic file. The value of R_FID will be the reference for accessing any information about this file.

Syntax

---

ENVI_OPEN_FILE, Fname [, /INVISIBLE] [, /NO_INTERACTIVE_QUERY] [, /NO_REALIZE] [, R_FID=variable]

Arguments

---

Fname

This is the name and path of the file to open.

Keywords

---

INVISIBLE (optional)

Set this keyword to prevent the file from automatically displaying in the ENVI Classic interface. This keyword only applies when using ENVI_OPEN_FILE in ENVI Classic programming. A file opened with the INVISIBLE keyword set will not appear in the Available Bands List and will not automatically display.

NO_INTERACTIVE_QUERY (optional)

Set this keyword to suppress bringing up the ENVI Header Information dialog when a valid header file does not exist for Fname. If you set this keyword and a valid header file does not exist, the file cannot be opened and an invalid file ID is returned in the keyword R_FID.

NO_REALIZE (optional)

Set this keyword to suppress opening the Available Bands List. If it is already open, this keyword has no effect.

R_FID (optional)

ENVI Classic library routines that result in new images also have an R_FID, or “returned FID.” This is simply a named variable containing the file ID to access the processed data. Specifying this keyword saves you the step of opening the new file from disk.
