This is the README for Image::SVG::Path version 0.24.

Image::SVG::Path is a "module" for the Perl computer programming language, a
library of computer code to install on a computer.  This document contains four
sections:

1. About - what the module does

2. Documentation - how to learn more about the module

3. Installation - how to install this module on a computer

4. Help - what to do if you get stuck

-----------------------------------------------------------------------------

1. ABOUT

Image::SVG::Path - read the "d" attribute of an SVG path

This module 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

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

    
    use FindBin '$Bin';
    use XML::Parser;
    use Image::SVG::Path 'extract_path_info';
    my $file = "$Bin/Home_for_the_aged.svg";
    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);
            for (@r) {
                if ($_->{svg_key} =~ /^[mM]$/i) {
                    print "MOVE TO @{$_->{point}}.\n";
                }
            }
        }
    }


produces output

    MOVE TO 15 119.
    MOVE TO 52 88.
    MOVE TO 198 88.
    MOVE TO 20 214.
    MOVE TO 148 214.


(This example is included as


SVG means "scalable vector graphics" and it is a standard of the W3
consortium. See "SVG standards" for details.  Although SVG is a type
of XML, the text in the "d" attribute of SVG paths is not XML but a
condensed form using single letters and numbers. This module is a
parser for that condensed format.

-----------------------------------------------------------------------------

2. DOCUMENTATION

You can read the documentation for the module online at the following websites:

    * http://search.cpan.org/perldoc?Image::SVG::Path
    * http://metacpan.org/release/Image-SVG-Path

(These links go to the latest version of the module.)

After installing the module, you can read the documentation on your computer
using

    perldoc Image::SVG::Path

-----------------------------------------------------------------------------

3. INSTALLATION

This module requires Perl version 5.6.1 or later.

To install the module from CPAN, use

    cpan Image::SVG::Path

If you have the App::cpanminus installer, you may prefer

    cpanm Image::SVG::Path

To install the module from the source file, Image-SVG-Path-0.24.tar.gz, follow
this sequence of commands:

    tar xfz Image-SVG-Path-0.24.tar.gz
    cd Image-SVG-Path-0.24
    perl Makefile.PL
    make
    make install

If you want to test the module before installing it, use "make test" after
"make" and before "make install".

-----------------------------------------------------------------------------
