I don't know what FxFactory does to create custom effects, and I
don't know that there is a preferred solution to your problem. That
method is not the typical way that plugins are created. You can
certainly write code that will assemble the expected FxPlug bundle
pieces, which should be very straightforward. There are a few items
that you will need to deal with on a per-plugin basis, though:
1. You will need to create a uniquely-named effect class (based upon
FxFilter, FxGenerator or FxTransition) to execute the effect in the
plugin. This is because Objective-C registers each class name at
runtime, so if you create two plugins that use the same class name,
the first-loaded plugin's class will be used by the second plugin.
2. For each plugin you will need to generate a pair of UUIDs, one to
associate with the plugin and one with its group in the plugin's
Info.plist file. You'll also need to store the plugin's class name in
the Info.plist file.
As far as the code to actually do this, I leave that as an exercise
for the reader. You should definitely read up on the FxPlug API and
rendering documentation so you know how plugins work.

Yes this exactly what I want. And I think this is the thing which
FxFactory application do, as far I understood. So, could you give
me the solution for this with explanation.

I am new to fxplug. And I wanted to create an fxplug plugin from a
cocoa application. What should be the right way to do this ? I have
fxPlug SDK installed. The specification is: I have an cocoa
application with UI having effects and image. And I want to create
fxplug as output on any button event.
OR
How can I create a fxplug as output with cocoa application. And I
don't
wanna use Xocde template for fxplug. That fxplug should get
created by
cocoa or carbon application.
Can anyone explain it in simple and step wise manner giving some
links
and hints.
Your description above didn't make it clear to me exactly what you
want
to do, but here's I understood it:
"I want to create a Cocoa application that will allow a user to
define an effect. When the user pushes a button in the UI, the
application will then create a FxPlug plugin that will implement
the effect."
Is that correct?
