generate the pictueres of mapped reaction in command line

when I  use the standardize map a reaction:

standardize  -c  "mapreaction : MappingStyle='CHANGING' "  "CCC(=O)N.O>>CCC(=O)O.N"  -o  reaction.smiles

how could I add some parameters  or use other command to generate the pictures with atom number  of  mapped reaction (reaction.smiles)  in command line?

thanks!

Here is an example how to generate the PNG image of the mapped reaction:

standardize -c "mapreaction:MappingStyle='CHANGING'" "CCC(=O)N.O>>CCC(=O)O.N" -f png:amap,w600h400 -o mapped.png
