Yes, you can load a CLR file for a contour map in Surfer via automation. All the CLR files for all the presets are saved to the installation file under the ColorScales folder. So you could use
'Load a CLR file for the contour layer ContourLayer.FillForegroundColorMap.LoadFile(SurferApp.Path+"\ColorScales\Rainbow.clr") 'Applies the above fill settings to the layer ContourLayer.ApplyFillToLevels(1, 1, 0)
See also the sample script ContourMap.bas in the \Samples\Scripts\ folder in the Surfer installation directory.
Surfer 9 and previous versions do not have the ability to load a CLR file or specify a preset colormap to a contour map in a script. Instead, you can specify the minimum and maximum colors and create a color gradation between them. For example:
'Set the colors to go from blue to red n = Levels.Count ColorInc = 255.0 / (n-1) For i=1 To n ColorInc = 255.0 * (i-1) / (n-1) Levels(i).Fill.foreColor = RGB(ColorInc,0,255-ColorInc) Next i 'Set the colors to go from blue to white m = Levels2.Count ColorInc2 = 255.0 / (m-1) For j=1 To m ColorInc2 = 255.0 * (j-1) / (m-1) Levels2(j).Fill.foreColor = RGB(ColorInc2,ColorInc2,255) Next j
