Constructor & Destructor Documentation

§ GradientFill()

gnash::GradientFill::GradientFill	(	Type	t,
		const SWFMatrix &	m,
		const GradientRecords &	recs = `GradientRecords()`
	)

Construct a GradientFill.

Optionally the records can be passed here. The actual matrix of the gradient depends on the type; the constructor handles this, and users should just pass the user matrix.

Member Function Documentation

§ focalPoint()

double gnash::GradientFill::focalPoint ( ) const

inline

Get the focal point of this GradientFill.

If the focal point is 0.0, it is a simple radial fill.

Referenced by gnash::StyleHandler::addFocalGradient(), gnash::renderer::openvg::StyleHandler::operator()(), and gnash::readFills().

§ getRecords()

const GradientRecords& gnash::GradientFill::getRecords ( ) const

inline

Referenced by gnash::renderer::openvg::StyleHandler::operator()().

§ matrix()

const SWFMatrix& gnash::GradientFill::matrix ( ) const

inline

References gnash::key::a, gnash::key::b, gnash::GradientRecord::ratio, and gnash::setLerp().

Referenced by gnash::renderer::openvg::StyleHandler::operator()(), gnash::AddStyles::operator()(), gnash::operator<<(), and setLerp().

§ record()

const GradientRecord& gnash::GradientFill::record ( size_t i ) const

inline

Query the GradientRecord at the specified index.

There are recordCount() records.

References gnash::key::d, and gnash::key::i.

Referenced by gnash::AggStyle::color(), gnash::Renderer_cairo::getPixel(), and setLerp().

§ recordCount()

size_t gnash::GradientFill::recordCount ( ) const

inline

Get the number of records in this GradientFill.

Referenced by gnash::AggStyle::color(), gnash::Renderer_cairo::getPixel(), gnash::operator<<(), and setLerp().

§ setFocalPoint()

void gnash::GradientFill::setFocalPoint ( double d )

Set the focal point.

Value will be clamped to the range -1..1; callers don't need to check.

References gnash::key::d.

Referenced by gnash::readFills().

§ setLerp()

void gnash::GradientFill::setLerp	(	const GradientFill &	a,
		const GradientFill &	b,
		double	ratio
	)

Set this fill to a lerp of two other GradientFills.

References gnash::GradientRecord::color, gnash::key::e, gnash::frnd(), gnash::key::i, gnash::lerp(), matrix(), gnash::GradientRecord::ratio, record(), recordCount(), gnash::SWFMatrix::set_lerp(), gnash::BitmapFill::type(), and type().

§ setRecords()

void gnash::GradientFill::setRecords ( const GradientRecords & recs )

inline

Referenced by gnash::readFills().

§ type()

Type gnash::GradientFill::type ( ) const

inline

Referenced by gnash::renderer::openvg::StyleHandler::operator()(), gnash::operator<<(), and setLerp().
