You are dealing here not with curves but elliptical arcs, so the maths is extremely simple. Here's a perl script that does the job and should be self-explanatory. Where you actually start the path is up to you. #!/usr/bin/perl use strict; # Rectangle my $height = 2.8569181; my $width = 90.898613; my $x = 20.280216; my $y = 838.27399; my $rx = 0.9670065; my $ry = 1.2499017; # My dims my $mx = $x; my $my = $y + $ry; my $v = $height - 2 * $ry; my $h = $width - 2 * $rx; # Print path print "<path d=\"" . "m $mx $my " . "v $v " . "a $rx $ry 0 0 0 $rx $ry " . "h $h " . "a $rx $ry 0 0 0 $rx -$ry " . "v -$v " . "a $rx $ry 0 0 0 -$rx -$ry " . "h -$h " . "a $rx $ry 0 0 0 -$rx $ry" . "\" />"; RESULT: <path d="m 20.280216 839.5238917 v 0.3571147 a 0.9670065 1.2499017 0 0 0 0.9670065 1.2499017 h 88.9646 a 0.9670065 1.2499017 0 0 0 0.9670065 -1.2499017 v -0.3571147 a 0.9670065 1.2499017 0 0 0 -0.9670065 -1.2499017 h -88.9646 a 0.9670065 1.2499017 0 0 0 -0.9670065 1.2499017" /> JD ------------------------------------ ----- To unsubscribe send a message to: svg-developers-unsubscr...@yahoogroups.com -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ----Yahoo!
