Detailed Description

The image object.

Constructor & Destructor Documentation

Image::Image ( const Rect &  rect, Bitmap  bitmap  )

explicit

Create a new image.

Image::Image ( const XmlAttributes &  attr, String  data  )

explicit

Create from XML stream.

Image::Image ( const XmlAttributes &  attr, Bitmap  bitmap  )

explicit

Create from XML stream with given bitmap.

Member Function Documentation

Object * Image::clone ( ) const

virtual

Clone object.

Implements ipe::Object.

Image * Image::asImage ( )

virtual

Return pointer to this object.

Reimplemented from ipe::Object.

Object::Type Image::type ( ) const

virtual

Implements ipe::Object.

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

virtual

Save image in XML stream.

Implements ipe::Object.

void Image::draw ( Painter &  painter ) const

virtual

Draw image.

Implements ipe::Object.

void Image::drawSimple ( Painter &  painter ) const

virtual

Draw simple version for selecting and transforming.

Implements ipe::Object.

void Image::accept ( Visitor &  visitor ) const

virtual

Call VisitImage of visitor.

Implements ipe::Object.

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.

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.

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

virtual

Compute possible vertex snapping position for transformed object.

Looks only for positions closer than bound. If successful, modify pos and bound.

Implements ipe::Object.

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.

Bitmap ipe::Image::bitmap ( ) const

inline

Return Bitmap of the image.
