#include <ipeimage.h>
Inherits ipe::Object.
The image object.
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.
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.
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.
Return distance of transformed object to point v. If larger than bound, can just return bound.
Implements ipe::Object.
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.
