Detailed Description

The image object.

Constructor & Destructor Documentation

IpeImage::IpeImage (  IpeRepository *  rep,
const IpeXmlAttributes &  attr,
IpeString  data
)  [explicit]
 

Create from XML stream.

IpeImage::IpeImage (  IpeRepository *  rep,
const IpeXmlAttributes &  attr,
IpeBitmap  bitmap
)  [explicit]
 

Create from XML stream with given bitmap.

IpeImage::IpeImage (  const IpeRect &  rect,
IpeBitmap  bitmap
)  [explicit]
 

Create a new image.

Member Function Documentation

IpeObject * IpeImage::Clone (   )  const [virtual]
 

Clone object.

Implements IpeObject.

IpeImage * IpeImage::AsImage (   )  [virtual]
 

Return pointer to this object.

Reimplemented from IpeObject.

void IpeImage::SaveAsXml (  IpePainter &  painter,
IpeStream &  stream,
IpeString  layer
)  const [virtual]
 

Save image in XML stream.

Implements IpeObject.

void IpeImage::Draw (  IpePainter &  painter  )  const [virtual]
 

Draw image.

Implements IpeObject.

void IpeImage::Accept (  IpeVisitor &  visitor  )  const [virtual]
 

Call VisitImage of visitor.

Implements IpeObject.

double IpeImage::Distance (  const IpeVector &  v,
const IpeMatrix &  m,
double  bound
)  const [virtual]
 

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

Implements IpeObject.

void IpeImage::AddToBBox (  IpeRect &  box,
const IpeMatrix &  m
)  const [virtual]
 

Extend box to include the object transformed by m.

For Ipe objects in a page, don't call this directly. The IpePgObject caches the bounding box, so it is far more efficient to call IpePgObject::BBox.

If called with an empty box, 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 IpeObject.

void IpeImage::SnapVtx (  const IpeVector &  mouse,
const IpeMatrix &  m,
IpeVector &  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 IpeObject.

IpeRect IpeImage::Rect (   )  const [inline]
 

Return the rectangle occupied by the image on the paper.

The transformation matrix is applied to this, of course.

IpeBitmap IpeImage::Bitmap (   )  const [inline]
 

Return IpeBitmap of the image.
