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.
