示例1: _renderItem
unsigned DrawingText::_renderItem(DrawingContext &ct, Geom::IntRect const &/*area*/, unsigned /*flags*/, DrawingItem * /*stop_at*/)
{
if (_drawing.outline()) {
guint32 rgba = _drawing.outlinecolor;
Inkscape::DrawingContext::Save save(ct);
ct.setSource(rgba);
ct.setTolerance(0.5); // low quality, but good enough for outline mode
for (ChildrenList::iterator i = _children.begin(); i != _children.end(); ++i) {
DrawingGlyphs *g = dynamic_cast<DrawingGlyphs *>(&*i);
if (!g) throw InvalidItemException();
Inkscape::DrawingContext::Save save(ct);
// skip glpyhs with singular transforms
if (g->_ctm.isSingular()) continue;
ct.transform(g->_ctm);
ct.path(*g->_font->PathVector(g->_glyph));
ct.fill();
}
return RENDER_OK;
}
// NOTE: this is very similar to drawing-shape.cpp; the only difference is in path feeding
