Question

I’m using a CvSeq of Cvpoint and it is created by cvApproxPoly.
I need to delete some points and insert some new ones.
I can delete the points with any problem, but when I try to insert I get an error:
“cannot convert parameter 3 from “CvPoint” to “const void *”

the code I wrote is

Cvpoint p;
p.x=1;
p.y=1;
cvInsert (mySeq, i, p);

how do I typecast p?

Answer 1

try cvSeqPush

call it as

Cvpoint p;
p.x=1;
p.y=1;
cvSeqPush(mySeq, &p);
