Clicking the "Edit" button will open the composition used by the plug-in inside Quartz Composer.
While a composition is being edited, FxFactory displays the following sheet:
Use Quartz Composer to make any changes to the plug-in rendering logic. When finished, save the composition by choosing the "Save" command under the "File" menu, and return to FxFactory. When you click the "Apply Changes" button, FxFactory will read back the changes you made to the composition.
If you have published new input ports, FxFactory will automatically create parameters that best match the new composition inputs. You can review and fix this initial guess via the parameters editing interface.
