Scene7 Publishing System (SPS) does not allow you to specify iscommansd for ZoomView. The only way is to apply this command is through a URL call like the following:
If you want to affect only the swatches, then qualify the iscommand modifier. The customer can add this line to the viewer call:
&imageSwatch.iscommand=op_sharpen=1
Finally, to find out what are the names of components used in specific viewer, see the following:

See the Components section with the list of all component's instance names present in the viewer.
