Member Function Documentation

void tuttle::plugin::component::ComponentPlugin::changedParam	(	const OFX::InstanceChangedArgs &	args,
		const std::string &	paramName
	)		`[virtual]`

called when a param has just had its value changed

Reimplemented from OFX::ImageEffect.

Definition at line 21 of file ComponentPlugin.cpp.

void tuttle::plugin::component::ComponentPlugin::getClipPreferences ( OFX::ClipPreferencesSetter & clipPreferences ) [virtual]

get the clip preferences

Reimplemented from OFX::ImageEffect.

Definition at line 69 of file ComponentPlugin.cpp.

References tuttle::plugin::ImageEffectGilPlugin::_clipDst, _paramToComponent, tuttle::plugin::component::eConvertToGray, tuttle::plugin::component::eConvertToRGB, tuttle::plugin::component::eConvertToRGBA, OFX::ePixelComponentAlpha, OFX::ePixelComponentRGB, OFX::ePixelComponentRGBA, OFX::ChoiceParam::getValue(), and OFX::ClipPreferencesSetter::setClipComponents().

Here is the call graph for this function:

bool tuttle::plugin::component::ComponentPlugin::isIdentity	(	const OFX::RenderArguments &	args,
		OFX::Clip *&	identityClip,
		double &	identityTime
	)		`[virtual]`

client is identity function, returns the clip and time for the identity function

If the effect would do no processing for the given param set and render arguments, then this function should return true and set the identityClip pointer to point to the clip that is the identity and identityTime to be the time at which to access the clip for the identity operation.

Reimplemented from OFX::ImageEffect.

Definition at line 57 of file ComponentPlugin.cpp.

void tuttle::plugin::component::ComponentPlugin::render ( const OFX::RenderArguments & args ) [virtual]

The overridden render function.

Parameters:

[in] args Rendering parameters

Implements OFX::ImageEffect.
