Every analysis has a boolean property HasAnalysisSpecificSettings. If this property is True, it means its settings are available from the ZOS-API directly. Otherwise, it means you’ll need to use a settings file or you might not even be able to access those settings. Geometric Bitamp Image Analysis returns False.

my_analysis = TheSystem.Analyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.GeometricBitmapImageAnalysis)
print(my_analysis.HasAnalysisSpecificSettings)

The latter approach is similar to what you’d do in ZPL and I wrote a topic about how to modify those settings that are not otherwise accessible some time ago here. In the settings of each analysis you have the following methods to perform the same operations as in ZPL more or less:

Hopefully this is clear, let me know if you need a more detailed example.

Take care,

It seems I wasn’t clear with my previous answer. The settings of Geometric Bitmap Analysis are not implemented in the ZOS-API yet. Therefore, I can understand that your code above doesn’t work. Instead, this is what you need to do:

geometric_bitmap_settings_filepath = "E:/custom_geometric_bitmap_analysis_settings.CFG"

geometric_bitmap_analysis = TheSystem.Analyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.GeometricBitmapImageAnalysis)
geometric_bitmap_settings = geometric_bitmap_analysis.GetSettings()
geometric_bitmap_settings.SaveTo(geometric_bitmap_settings_filepath)
geometric_bitmap_settings.ModifySettings(geometric_bitmap_settings_filepath, "GBM_OUTPUT", "061820_Myfile.JPG")
geometric_bitmap_settings.LoadFrom(geometric_bitmap_settings_filepath)

geometric_bitmap_analysis.ApplyAndWaitForCompletion()

The ModifySettings method in the ZOS-API is similar to its ZPL counterpart MODIFYSETTINGS. It takes a string code (in this case GBM_OUTPUT) to modify a particular setting of an analysis inside the *.CFG file associated to it. The list of string codes can be found in the ZPL Help section of MODIFYSETTINGS.

Note that with this way of modifying the settings, you need to create the *.CFG file with SaveTo. This is similar to pressing the Save button at the bottom-right of your analysis settings.

I hope this is clearer. In the future, I believe ANSYS wants to have all the settings implemented in the ZOS-API but in the meantime we have to use this method.

got it, thanks for your help. for anybody interested in how I ultimately did this, I’m making zemax analyze the last surface with 

last_surface_number = TheLDE.NumberOfSurfaces - 1
gia_settings = gia_run.GetSettings() 
gia_settings.Surface.SetSurfaceNumber(last_surface_number) #analyze GIA on the last surface 

best,

@David.Nguyen

what is best way to save GeometricBitmapImageAnalysis results as image?

I finded txt way. is here image options?

@David.Nguyen how I can customize folder where will be saved image?
I finded changing folder option(which for some reason not work for me), but not sure if zemax can understand where find “input image” for this analysis, if I change default folder to different in cycle  

@Aleksandr.Makarov 

Could you please create a new topic for this question? I feel it departs from the original topic here. Also, could you clarify in comparison to what you notice the 2x increase in time?

Take care,

David

That’s an excellent solution.

Sorry if I wasn’t clear when I listed the methods of IAS_Surface, but you could also try:

gia_settings.Surface.UseImageSurface()

Take care,

David
