vectorising text 1.14.2
vectorising text 1.14.2
hi everyone,
i have a simple class that has one override as follows :
void textdumpvectorizer:olylineout(odint32 n, const odgepoint3d* pts) {
// here lines should be processed
e3d::cdbug::log(e3d::cdbug::elvl::dldbg, e3d::cdbug::etype::ltlayout, e3d::cdbug::eops:pcrte,
l"function", l"textdumpvectorizer", l"polylineout opendwg vectoizer");
if( m_apldr.valid() && m_aptextent.valid() ) {
m_apldr->bgnaddpnts(m_aptextent.get());
const odgepoint3d *curpnt = pts;
for( int i = 0; i < n; i++ ) {
m_apldr->addpnt2ent(m_aptextent.get(), odgepoint3d(curpnt->x, curpnt->y, curpnt->z));
curpnt++;
}
m_apldr->endaddpnts(m_aptextent.get());
}
}
i initiate text vectorizing as follows :
odstaticrxobject<textdumpvectorizer> dv;
dv.settextent(ptext);
dv.setldr(this);
odstaticrxobject<odgicontextfordbdatabase> gicontext;
gicontext.setdatabase(odtextptr->database());
dv.setdrawcontext(&dv);
dv.setcontext(&gicontext);
dv.output().setdestgeometry(dv);
dv.draw(odtextptr);
all was great until i just upgraded to 1.14.2.
i get an access violation as such :
first-chance exception at 0x098d41c9 (opendwgldr.edl) in e3dtestprg.exe: 0xc0000005: access violation writing location 0x00000000
now i get a a call stack that seems to go into a loop as follows :

snipped out about 1000 lines of the exact same repeated text.

is there any work around, or somehting i am doing wrong?

the drawing i am using is the simple facility.dwg that comes with autocad.

you're doing something wrong.
if you inherit your conveyor node from simplifier, you must override either polygonout() or triangleout(). else you'll get exception you are getting now in attempt to simplify first filled primitive.
probably prev. version didn't treat ttf as filled primitive by error.
sincerely yours,
