Member Function Documentation

Object * Image::clone ( ) const

virtual

Clone object.

Implements ipe::Object.

References Image().

Image * Image::asImage ( )

virtual

Return pointer to this object.

Reimplemented from ipe::Object.

Object::Type Image::type ( ) const

virtual

Implements ipe::Object.

References ipe::Object::EImage.

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

virtual

Save image in XML stream.

Implements ipe::Object.

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

void Image::draw ( Painter & painter ) const

virtual

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::transform(), ipe::Object::transformations(), ipe::Painter::untransform(), ipe::Rect::width(), ipe::Vector::x, and ipe::Vector::y.

void Image::drawSimple ( Painter & painter ) const

virtual

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().

void Image::accept ( Visitor & visitor ) const

virtual

Call VisitImage of visitor.

Implements ipe::Object.

References ipe::Visitor::visitImage().

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

virtual

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().

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

virtual

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().

void Image::snapCtl	(	const Vector &	mouse,
		const Matrix &	m,
		Vector &	pos,
		double &	bound
	)		const

virtual

Compute control point snapping position for transformed object.

Looks only for positions closer than bound. If successful, modify pos and bound. The default implementation does nothing.

Reimplemented from ipe::Object.

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

Rect ipe::Image::rect ( ) const

inline

Return the rectangle occupied by the image on the paper.

The transformation matrix is applied to this, of course.

Referenced by saveAsXml().

Bitmap ipe::Image::bitmap ( ) const

inline

Return Bitmap of the image.
