viewport clipping
viewport clipping
i use dd 1.11 for creating our own rendering application with own vectorizedevice and vectorizeview.
for viewport clip i use following code that i find in exgsgdivectorizedevice.cpp
code:
bool bclipped = false;
if(m_nrcpoints.size())
{
bclipped = true;
device()->pushviewportclip(m_nrcpoints.getptr(), m_nrccounts.getptr(), m_nrccounts.size());
}
else if(device()->numviews()>1)
{
bclipped = true;
odgsdcpoint dcpoint1, dcpoint2;
screenrect(dcpoint1, dcpoint2);
device()->pushviewportclip(dcpoint1, dcpoint2);
}
odgsbasevectorizeview::update();
if(bclipped)
{
device()->popviewportclip();
}
but autocad don't use clipping only if object is on frozen layer, if layer is switched of just clipping border doesn't display. dwgdirect doesn't use clipping if object is on frozen or switched off layer (see attached files).
can i obtain same clipping boundary as autocad used?
what the purpose of member variable m_nrcpoints?
attached images
this is dd bug to be fixed.

do you plan include this fix in 1.11 update?

and what about 1.14.02 ?
it seem still to not work, but maybe i'm doing sth wrong in my code?
