Member Function Documentation

◆ clone()

Object * Image::clone ( ) const

overridevirtual

Clone object.

Implements ipe::Object.

References Image().

◆ asImage()

Image * Image::asImage ( )

overridevirtual

Return pointer to this object.

Reimplemented from ipe::Object.

◆ type()

Object::Type Image::type ( ) const

overridevirtual

Implements ipe::Object.

References ipe::Object::EImage.

◆ saveAsXml()

void Image::saveAsXml	(	Stream &	stream,
		String	layer
	)		const

overridevirtual

Save image in XML stream.

Implements ipe::Object.

References ipe::Bitmap::objNum(), ipe::Attribute::OPAQUE(), rect(), ipe::Object::saveAttributesAsXml(), and ipe::Attribute::string().

◆ draw()

void Image::draw ( Painter & painter ) const

overridevirtual

Draw image.

Implements ipe::Object.

References ipe::Rect::bottomLeft(), ipe::Painter::drawBitmap(), ipe::Rect::height(), ipe::Object::matrix(), ipe::Painter::pop(), ipe::Painter::popMatrix(), ipe::Painter::push(), ipe::Painter::pushMatrix(), ipe::Painter::setOpacity(), ipe::Painter::transform(), ipe::Object::transformations(), ipe::Painter::untransform(), ipe::Rect::width(), ipe::Vector::x, and ipe::Vector::y.

◆ drawSimple()

void Image::drawSimple ( Painter & painter ) const

overridevirtual

Draw simple version for selecting and transforming.

Implements ipe::Object.

References ipe::Painter::drawPath(), ipe::EStrokedOnly, ipe::Object::matrix(), ipe::Painter::newPath(), ipe::Painter::popMatrix(), ipe::Painter::pushMatrix(), ipe::Painter::rect(), ipe::Painter::transform(), ipe::Object::transformations(), and ipe::Painter::untransform().

◆ accept()

void Image::accept ( Visitor & visitor ) const

overridevirtual

Call VisitImage of visitor.

Implements ipe::Object.

References ipe::Visitor::visitImage().

◆ distance()

double Image::distance	(	const Vector &	v,
		const Matrix &	m,
		double	bound
	)		const

overridevirtual

Return distance of transformed object to point v. If larger than bound, can just return bound.

Implements ipe::Object.

References ipe::Rect::addPoint(), ipe::Rect::bottomLeft(), ipe::Rect::bottomRight(), ipe::Rect::certainClearance(), ipe::Object::matrix(), ipe::Rect::topLeft(), and ipe::Rect::topRight().

◆ addToBBox()

void Image::addToBBox	(	Rect &	box,
		const Matrix &	m,
		bool	cp
	)		const

overridevirtual

Extend box to include the object transformed by m.

For objects in a page, don't call this directly. The Page caches the bounding box of each object, so it is far more efficient to call Page::bbox.

Control points that lie outside the visual object are included if cp is true.

If called with an empty box and cp == false, the result of this function is a tight bounding box for the object, with a little leeway in case the boundary is determined by a spline (it has to be approximated to perform this operation).

Implements ipe::Object.

References ipe::Rect::addPoint(), ipe::Rect::bottomLeft(), ipe::Rect::bottomRight(), ipe::Object::matrix(), ipe::Rect::topLeft(), and ipe::Rect::topRight().
