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().

snapCtl()

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

overridevirtual

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()

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()

Bitmap ipe::Image::bitmap ( ) const

inline

Return Bitmap of the image.

Referenced by ipe::BitmapFinder::visitImage().

setAttribute()

bool Image::setAttribute ( Property  prop, Attribute  value  )

overridevirtual

Set an attribute on this object.

Returns true if an attribute was actually changed.

Reimplemented from ipe::Object.

References ipe::EPropOpacity, opacity(), ipe::Object::setAttribute(), and setOpacity().

getAttribute()

Attribute Image::getAttribute ( Property  prop ) const

overridevirtualnoexcept

Get setting of an attribute of this object.

If object does not have this attribute, returnes "undefined" attribute.

Reimplemented from ipe::Object.

References ipe::EPropOpacity, ipe::Object::getAttribute(), and opacity().

setOpacity()

void Image::setOpacity

(

Attribute

opaq

)

Set opacity of the object.

Referenced by setAttribute().

opacity()

Attribute ipe::Image::opacity ( ) const

inline

Return opacity of the opject.

Referenced by getAttribute(), and setAttribute().
