Detailed Description

Provides user-friendly masking and channel-selection controls to any operator. This makes the implementation of the operators much simpler and allows the basic operators to be much faster when used outside Nuke.

The wrapper uses the in_channels() and out_channels() calls of the subclass to figure out what channels it needs from it, intesects this with the user-settable channel selector, and only asks the subclass to calculate those. All other channels will be copied unchanged from input0(). The user can also select a "mask" channel, this is used to mix the original and final results. It can also do a constant dissolve between the input and result, controlled by the enable knob on the control panel.

Much work is done to avoid calling the inner operator for any data that is not going to be used. Zero channels are detected and skipped, and the mask is checked first and only the region inside it is requested.

Constructor & Destructor Documentation

NukeWrapper::NukeWrapper ( PixelIop * op )

If the NukeWrapper knows the wrapped Iop is a PixelIop subclass, it will call PixelIop::pixel_engine() directly, as this saves a lot of memory and cache space because it avoids getting the input pixels twice. This also enables the unpremultiply controls.

The op's engine() will not be called, so you should not override the PixelIop::engine(). If the subclass does, be sure to cast back to an Iop so that the Iop constructor is called.

References DD::Image::Iop::iop(), MAX(), DD::Image::Op::minimum_inputs(), and DD::Image::Op::parent().

NukeWrapper::NukeWrapper ( Iop * op )

The constructor takes a pointer to the Iop to "wrap". By default the full capabilities of the NukeWrapper are enabled, you can use the noMix(), noChannels(), noMask(), and noPremult() methods to turn off controls immediately after the constructor.

References DD::Image::Iop::iop(), MAX(), DD::Image::Op::minimum_inputs(), and DD::Image::Op::parent().

NukeWrapper::~NukeWrapper ( )

This deletes the iop!

void NukeWrapper::knobs ( Knob_Callback f )

overridevirtual

The knobs this creates are controlled by the flags argument sent to the constructor. The iop's knobs() function is called in the middle of this, after the channels and before the mask knobs are made.

Reimplemented from DD::Image::Op.

int NukeWrapper::knob_changed ( Knob * k )

overridevirtual

Shows only the relevant maskChannel control depending on whether the mask input is connected and being used. This avoids questions about what happens when you set both of them (the answer is that the maskChannelInput is used and the mask input is ignored).

This also calls knob_changed() on the wrapped Iop.

int NukeWrapper::split_input ( int n ) const

overridevirtual

const OutputContext & NukeWrapper::inputContext	(	int	n,
		int	offset,

overridevirtual

Passed through to the iop. Any changes it makes to input 0 will also effect the masked-off area or the turned-off channels, which may not be what the user expects.

void NukeWrapper::_request	(	int	x,
		int	y,
		int	r,
		int	t,
		ChannelMask	channels,
		int	count
	)

overridevirtual

Calls request() on the inner Iop, which will usually cause a request() to be done of the inputs to this Iop. If the mask or blending is enabled this will also call request() on input0() and this usually results in a count of 2 and the cache being enabled on the input.

If the op is a PixelIop request() of the input is called with count = 0, which should prevent the cache from being created.

Reimplemented from DD::Image::Iop.

References DD::Image::IopInfoOwner::black_outside(), DD::Image::IopInfoOwner::info(), DD::Image::Iop::input(), DD::Image::Iop::input0(), DD::Image::Iop::iop(), DD::Image::Box::r(), DD::Image::Iop::request(), DD::Image::Box::t(), DD::Image::Box::x(), and DD::Image::Box::y().

void NukeWrapper::engine	(	int	y,
		int	x,
		int	r,
		ChannelMask	channels,
		Row &	row
	)

overridevirtual

Calls engine() of the Iop, and (depending on the settings) this also reads raw data in from the input and mixes it together with the iop output to produce the final image.

If the operator is a PixelIop, PixelIop::pixel_engine() is called directly to avoid having to read a row twice from the input.

If a mask is enabled and the process-mask flag is off, the mask is looked at first, and only the non-zero region is requested with the x and r arguments to the iop's engine. If the mask is completely blank no line is asked for at all. Make sure your wrapped Iop can handle x and r changing.

Implements DD::Image::Iop.

void NukeWrapper::in_channels	(	int	n,
		ChannelSet &	channels
	)		const

overridevirtual

Fairly complex, this returns the correct set taking into account the in_channels() of the Iop, and the settings of premult, mask, and the mix slider.

NukeWrapper * NukeWrapper::noMix ( )

You can call this immediately after the constructor to remove the "mix" control. You don't want this if your operator has a mixing or amplitude control of it's own.

NukeWrapper * NukeWrapper::noChannels ( )

You can call this immediately after the constructor to remove the channel selector controls. You don't want this if your operator does not naturally operate on all channels.

Returns this to allow you to call this in the same statement as the constructor.

NukeWrapper * NukeWrapper::noMask ( )

You can call this immediately after the constructor to remove the "mask" control and the extra mask input. You don't want this if your operator has it's own masking or some other way of using a channel to control it's amplitude.

NukeWrapper * NukeWrapper::mixLuminance ( )

You can call this immediately after the constructor to enable the "luminance mix" control. The control is a slider. Changing the slider to any value between 0-1 will mix the original luminance channel (i.e. Y) with altered luminance. The value 0 meaning that the altered luminance will be used, and 1 being the original luminance. Note that for conversion it uses YCbCr color space. The default state of this control is off and "mix luminance" value is 0.

NukeWrapper * NukeWrapper::noUnpremult ( )

You can call this immediately after the constructor to remove the "unpremult by" control. You don't want this if your operator requires premultiplied images.

PlanarI * NukeWrapper::getPlanarI ( )

overridevirtual

get the PlanarI for this NukeWrapper; this returns NULL if it prefers row-based access; or a pointer to the PlanarI describing the plane preferences if it prefers planar access

Reimplemented from DD::Image::Iop.

References DD::Image::Iop::getPlanarI(), and DD::Image::Iop::iop().

void NukeWrapper::doFetchPlane ( DD::Image::ImagePlane & ip )

overridevirtual

get the image data as a plane; will pass-through if possible, otherwise may fall back to row-based processing.

Reimplemented from DD::Image::Iop.

std::string DD::Image::NukeWrapper::getLibraryName ( ) const
