We are using ENVI_FX_RULEBASED_DOIT to classify large TIF files into preselected classes. We need to speed up the processing time by not exporting the vector attributes. What is the syntax for suppressing EXPORT_VECTOR_ATTRIBUTES? When we don't include that Keyword the vector attributes are exported anyway. Thank you! envi_doit, 'envi_fx_rulebased_doit', $ fid=fid, pos=pos, dims=dims, $ r_fid=r_fid, merge_level=80.0, $ scale_level=10.0, $ rule_filename=rule_file, $ classification_raster_filename=classification_raster_filename, $ segmentation_raster_filename=segmentation_raster_filename, $ vector_filename=vector_filename, $ SEGMENT_BANDS=[0,1], MERGE_BANDS=[0,1]
