How can I export multiple SRF files to bitmap images using Surfer automation?

The attached script will export all SRF files in the specified directory to GIF.  The name of each exported file will match the name of the SRF.  Prior to running the script, ensure the file directory and export format are set as desired in the User Variables section.

To run this script:

  1. Copy the script below, or download the attached BAS file: ExportAll.bas.
  2. In a Windows Explorer window, navigate to C:\Program Files\Golden Software\Surfer 16.
  3. Double click on Scripter.exe to launch Scripter.
  4. Press Ctrl+A to select all of the existing lines then press Delete.
  5. If you copied this script, press Ctrl+V to paste it into Scripter. If you downloaded it, click File | Open, select the BAS file from your downloads directory, and click Open.
  6. Edit the file_directory on line 11 to point to the location of your files.
  7. Click Script | Run to run the script.


Sub Main

'Opens all SRF file in directory
'Exports each to GIF

''''''''''''' User Variables ''''''''''''''''''

file_extension	= "srf"

file_directory	= "C:\temp\grids\"

export_format = "gif"

	Set surf = CreateObject("surfer.application")
	surf.Visible = True
	Debug.Print surf.Version

	file_extension	= LCase(Right(file_extension,(Len(file_extension) - InStrRev(file_extension,"."))))
	If  Len(file_directory)-InStrRev(file_directory,"\") <> 0 Then file_directory = file_directory + "\"

	srf_file = Dir( file_directory  + "*." + file_extension)

	On Error GoTo FileError
	While srf_file <> ""
		'Define output grid file directory & name
		export_file	= file_directory + Left(srf_file, Len(srf_file)-(Len(srf_file)-InStrRev(srf_file,".")+1) ) + "." + export_format

		'Declares Plot As an Object And opens an SRF file
   		Dim Plot As Object
		Set Plot = surf.Documents.Open(file_directory + srf_file)
		Plot.Export2(export_file, filterid:=export_format)

		Debug.Print srf_file
		srf_file = Dir() 'get next file

	Exit Sub

	'Print a meaningful error message for each file that did not grid correctly
	Debug.Print  "Error:	" + srf_file + "						" + Err.Description
	Resume Next

End Sub
