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.
