示例1: A
void
LPEMirrorSymmetry::doOnApply (SPLPEItem *lpeitem)
{
using namespace Geom;
SPItem *item = SP_ITEM(lpeitem);
Geom::Matrix t = sp_item_i2d_affine(item);
Geom::Rect bbox = *item->getBounds(t); // fixme: what happens if getBounds does not return a valid rect?
Point A(bbox.left(), bbox.bottom());
Point B(bbox.left(), bbox.top());
A *= t;
B *= t;
Piecewise<D2<SBasis> > rline = Piecewise<D2<SBasis> >(D2<SBasis>(Linear(A[X], B[X]), Linear(A[Y], B[Y])));
reflection_line.set_new_value(rline, true);
}示例2: A
void
LPEMirrorSymmetry::doOnApply (SPLPEItem const* lpeitem)
{
using namespace Geom;
// fixme: what happens if the bbox is empty?
// fixme: this is probably wrong
Geom::Affine t = lpeitem->i2dt_affine();
Geom::Rect bbox = *lpeitem->desktopVisualBounds();
Point A(bbox.left(), bbox.bottom());
Point B(bbox.left(), bbox.top());
A *= t;
B *= t;
Piecewise<D2<SBasis> > rline = Piecewise<D2<SBasis> >(D2<SBasis>(SBasis(A[X], B[X]), SBasis(A[Y], B[Y])));
reflection_line.set_new_value(rline, true);
