void tuttle::host::ofx::imageEffect::OfxhImageEffectNode::getClipPreferencesAction ( ) [virtual]

Run the clip preferences action from the effect.

This will look into the input clips and output clip and set the following properties that the effect should fetch the image at.

pixel depth
components
pixel aspect ratio It will also set on the effect itself
whether it is continuously samplable
the premult state of the output
whether the effect is frame varying
the fielding of the output clip

This will be run automatically by the effect in the following situations...

an input clip is changed
a clip preferences slave param is changed

The host still needs to call this explicitly just after the effect is wired up.

the idea here is the clip prefs live as active props on the effect and are set up by clip preferences. The action manages the clip preferences bits. We also monitor clip and param changes and flag when clip prefs is dirty. call the clip preferences action

create the out args with the stuff that does not depend on individual clips

call the get region of interest action on the plugin for the given frame and renderscale. The render RoI is passed in in roi, the std::map will contain the requested rois. Note That this call will check for tiling support and for default replies and set up the correct rois in these cases as well

get the region of interest for each input and return it in the given std::map

No tiling support on the effect at all. So set the roi of each input clip to be the RoD of that clip.
