Agg::trans_single_path Calculating path Lengths

header file:agg/include/agg_trans_single_path.h

source file:agg/src/agg_trans_single_path.cpp

1 total_lengthStatistical path length

agg::p ath_storageps;

Ps.move_to (100,20);

Ps.line_to (10,200);

Ps.line_to (200,200);

Agg::trans_single_path Tspath;

Tspath.add_path (PS);

Double npathlen= tspath.total_length ();

2 transform

I don't know for a moment

Agg::trans_single_path Tcurve;

Tcurve.add_path (M_path_storage);

Double len = Tcurve.total_length ();

int n = 3;

Double x = len/n;

Couble y = 0;

Tcurve.transform (&x, &y);

Here x, y been transformed to the rightvalue.

Summary: Use this class to render text based on the direction of the path segment, which is not currently known:
