示例1: DBbox
void trend::TrendBase::grcwire (int4b* pdata, unsigned psize, WireWidth width)
{
// first check whether to draw only the center line
DBbox wsquare = DBbox(TP(0,0),TP(width,width));
bool center_line_only = !wsquare.visible(topCTM() * scrCTM(), visualLimit());
_grcLayer->wire(pdata, psize, width, center_line_only);
}示例2: if
/*! A temporary Draw (during move/copy operations) of the container contents
on the screen using the virtual quadTree::tmp_draw() method of the
parent object. */
void laydata::tdtlayer::motion_draw(const layprop::DrawProperties& drawprop,
ctmqueue& transtack) const {
// check the entire layer for clipping...
DBbox clip = drawprop.clipRegion();
if (empty()) return;

if ( clip.cliparea(areal) == 0 ) return;
else if (!areal.visible(drawprop.ScrCTM())) return;
quadTree::motion_draw(drawprop, transtack);
}示例3:
short laydata::quadTree::clip_type(tenderer::TopRend& rend) const
{
if (empty()) return 0;
// check the entire holder for clipping...
DBbox clip = rend.clipRegion();
DBbox areal = _overlap.overlap(rend.topCTM());

if ( ( 0.0 == clip_area ) || (!areal.visible(rend.ScrCTM())) ) return 0;
if (0.0 < clip_area) return 1;
else return -1;
}示例4: if
