Image::SVG::Path 0.07

Image::SVG::Path is Perl module that extracts information contained in the "d" attribute of an SVG < path > element and turns it into a simpler series of steps.

For example, an SVG < path > element might take the form

< path d="M9.6,20.25c0.61,0.37,3.91,0.45,4.52,0.34c2.86-0.5,14.5-2.09,21.37-2.64c0.94-0.07,2.67-0.26,3.45,0.04"/ >

Using an XML parser, such as XML::Parser,

 use XML::Parser;
 use Image::SVG::Path 'extract_path_info';
 my $p = XML::Parser->new (Handlers => {Start => \& start});
 $p->parsefile ($file)
 or die "Error $file: ";

 sub start
 {
 my ($expat, $element, %attr) = @_;

 if ($element eq 'path') {
 my $d = $attr{d};
 my @r = extract_path_info ($d);
 # Do something with path info in @r
 }
 }

SVG means "scalable vector graphics" and it is a standard of the W3 consortium. See http://www.w3.org/TR/SVG/ for the full specification. See http://www.w3.org/TR/SVG/paths.html for the specification for paths. Although SVG is a type of XML, the text in the d attribute of SVG paths is not in the XML format but in a more condensed form using single letters and numbers. This module is a parser for that condensed format.

SYNOPSIS

 use Image::SVG::Path 'extract_path_info';
 my @path_info = extract_path_info ($path_d_attribute);
