When I try to start the painter,here comes the error that --order requires arguments.I wonder how can I solve the error!thank you!

You need to specify the file generated by the first command into the order flag. Example:

$ sudo splatplan -i image.png -o output.file
$ sudo splatplot --order output.file

(The file extension of the output doesn't really matter)
