How to export vectors with custom options?! (Python API)

raffaellof

I'm exporting features from Global Mapper Workspace to shapefile and I need to export the Feature Type as an attribute (for future queries). I'm working with GlobalMapper Python SDK and running my script in a Python environment.

Reading docs (https://www.bluemarblegeo.com/knowledgebase/global-mapper-python-23/Enumerations/EnumExport.html): "use GM_ExportOptsSHP_t for aFormatOptions parameter to GM_ExportVector", GM_ExportOptsSHP_t class itself has 3 attributes (mAddLabelAttr, mAddLayerAttr and mAddStyleAttr that should include GM_TYPE, label, etc to the exported dbf) but the aFormatOptions parameter only accepts integer values ​​and the GM_ExportOptsSHP_t class seems to have no method to return an int.

Here is a code example:

exported_features = []

# Load all layers from file
err, array_ptr, array_size = gm.LoadLayerList(workspace_path, gm.GM_LoadFlags_UseDefaultLoadOpts)
if err:
    quit()
all_layers = gm.GM_LayerHandle_array_frompointer(array_ptr)

# Vector layers only
vector_layers = []
for layer in gm.carray_to_list(all_layers, array_size):
    if gm.GetLayerInfo(layer).mHasVectorData:
        vector_layers.append(layer)

for layer in vector_layers:
    name = gm.GetLayerInfo(layer).mDescription
    name_wo_ext = name[:name.index(".")] if "." in name else name
    destination = os.path.join(target_dir, name_wo_ext) + ".shp"
    # Export all layer content
    err = gm.ExportVector(
        aFilename=destination,
        aFormat=gm.GM_Export_Shapefile,
        aLayer=layer,
        aWorldBounds=None,
        aFlags=gm.GM_VectorExportFlags_GenPRJFile + gm.GM_VectorExportFlags_ExportAll + gm.GM_VectorExportFlags_ExportAttrs,
        aFormatOptions=0x0
    )
    if not err:
        exported_features.append(name_wo_ext)
        
    else:
        print(err)
print(exported_features)

How can i use GM_ExportOptsSHP_t in this example? Is there any workaround to include the <Feature Type> inside attributes?!

Thanks 😉
