CIGAL Reference Manual, Chapter 3 (Functions): trace
Trace -- Generate vector list by tracing an image intensity contour
usage: numvecs = trace(mode,v0,dir,spacng,loval,hival)
TRACE follows an intensity contour in an image, generating a list of graphics vectors along its path.
MODE (octal) 1 1o stop at sharp corners or dead ends 2 2o store image intensity as vector intensity 4 4o for line tracing, draw vectors in center of line 8 10o for line tracing, store line width as vector width 16 20o trace in bursts with pauses 32 40o for closed trace (mode & 1) don't set direction automatically 64 100o don't stop when loop is closed 128 200o pause at sharp corners or dead ends
For now TRACE returns number of vectors added to VECS list. Perhaps someday should return VLIST pointer?
