VAX_IEEE_DOIT

VAX_IEEE_DOIT

Use this procedure to perform VAX IEEE floating-point conversion.

Syntax


ENVI_DOIT, 'VAX_IEEE_DOIT', /COPY_HEADER, IN_NAME=string, OFFSET=value, OUT_NAME=string

Keywords


COPY_HEADER

Set this keyword to specify that the header should be copied to the new output file.

IN_NAME

Use this keyword to specify an input filename for the VAX IEEE data.

OFFSET

Use this keyword to specify a byte offset to the start of the VAX IEEE floating-point data.

OUT_NAME

Use this keyword to specify a string with the output filename for the resulting data. If you set the keyword IN_MEMORY, you do not need to specify OUT_NAME.

Example


PRO EXAMPLE_VAX_IEEE_DOIT
  compile_opt IDL2
  ; First restore all the base save files.
  envi, /restore_base_save_files
   
  ; Initialize ENVI and send all errors
  ; and warnings to the file batch.txt
  envi_batch_init, log_file='batch.txt'
   
  ; Set the input VAX filename.
  offset = 0L
  in_name = 'vaxdata'
  out_name = 'testimg'
   
  ; Perform the VAX IEEE conversion.
  envi_doit, 'vax_ieee_doit', $
  in_name=in_name, out_name=out_name, $
  offset=offset
   
  ; Exit ENVI
  envi_batch_exit
