Using SVG, you<BR>can generate SVG objects, embed other SVG instances into it, access the DOM<BR>object, create and access javascript, and generate SMIL animation content.<BR></pre><pre>Generating SVG is a simple three step process:<BR><BR><BR><A NAME="_pod_1 The first step is to construct a new SVG object with L<"new">."> 1 The first step is to construct a new SVG object with L<"new">.</A><BR><A NAME="_pod_"> </A><BR><A NAME="_pod_"> </A><BR><BR>The <a href="#_pod_"xmlify"">"xmlify"</a> method takes a number of optional arguments that control how SVG<BR>renders the object into XML, and in particular determine whether a stand-alone<BR>SVG document or an inline SVG document fragment is generated:<BR><BR><BR><A NAME="_pod_-stand-alone"> -stand-alone</A><BR> A complete SVG document with its own associated DTD. A namespace for the SVG<BR>elements may be optionally specified.<BR><BR><A NAME="_pod_-in-line"> -in-line</A><BR> An in-line SVG document fragment with no DTD that be embedded within other XML<BR>content. As with stand-alone documents, an alternate namespace may be specified.<BR><BR><BR>No XML content is generated until the third step is reached. Up until this<BR>point, all constructed element definitions reside in a DOM-like data structure<BR>from which they can be accessed and modified.<BR></pre><pre>None. However, SVG permits both options and additional element methods to be<BR>specified in the import list. These options and elements are then available<BR>for all SVG instances that are created with the <a href="#_pod_"new"">"new"</a> constructor. For example,<BR>to change the indent string to two spaces per level:<BR><BR> use SVG qw(-indent => " ");<BR><BR>With the exception of -auto, all options may also be specified to the <a href="#_pod_"new"">"new"</a><BR>constructor. The currently supported options are:<BR><BR> -auto enable autoloading of all unrecognised method calls (0)<BR> -indent the indent to use when rendering the SVG into XML ("\t")<BR> -inline whether the SVG is to be standalone or inlined (0)<BR> -printerror print SVG generation errors to standard error (1)<BR> -raiseerror die if a generation error is encountered (1)<BR> -nostub only return the handle to a blank SVG document without any elements<BR><BR>SVG also allows additional element generation methods to be specified in the<BR>import list. For example to generate 'star' and 'planet' element methods:<BR><BR> use SVG qw(star planet);<BR><BR>or:<BR><BR> use SVG ("star","planet");<BR><BR>This will add 'star' to the list of elements supported by SVG.pm (but not of<BR>course other SVG parsers...). Alternatively the '-auto' option will allow<BR>any unknown method call to generate an element of the same name:<BR><BR> use SVG (-auto => 1, "star", "planet");<BR><BR>Any elements specified explicitly (as 'star' and 'planet' are here) are<BR>predeclared; other elements are defined as and when they are seen by Perl. Note<BR>that enabling '-auto' effectively disables compile-time syntax checking for<BR>valid method names.<BR><BR><b>Example:</b><BR><BR> use SVG (<BR> -auto => 0,<BR> -indent => " ",<BR> -raiserror => 0,<BR> -printerror => 1,<BR> "star", "planet", "moon"<BR> );<BR></pre></TD></TR></TABLE><A NAME="MethDesc"></A><HR><H2>Methods description</H2><FONT COLOR="RED"><B>None available.</B></FONT><BR><A NAME="MethCode"></A><HR><H2>Methods code</H2><FONT COLOR="RED"><B>No methods available.</B></FONT><BR><A NAME="General"></A><HR><H2>General documentation</H2><TABLE BORDER="0" WIDTH="100%" CELLSPACING="0"><TR BGCOLOR="#4492df"><TD><A NAME="_pod_VERSION"><B>VERSION</A></B></TD><TD><A HREF="#TOP">top</A></TD></TR><TR><TD COLSPAN="2"><pre>Version 2.24 (29.01.03)<BR>Covers SVG-2.27 distribution<BR></pre></TD></TR><TR BGCOLOR="#4492df"><TD><A NAME="_pod_SEE ALSO(1)"><B>SEE ALSO(1)</A></B></TD><TD><A HREF="#TOP">top</A></TD></TR><TR><TD COLSPAN="2"><pre> perl(1), <a href="http://roasp.com" target="urlWin">http://roasp.com</a>VG::Element>, <a href="http://roasp.com" target="urlWin">http://roasp.com</a>VG::Parser><BR> <a href="http://roasp.com" target="urlWin">http://roasp.com</a>/<BR> <a href="http://www.w3c.org/Graphics/SVG" target="urlWin">http://www.w3c.org/Graphics/SVG</a>/<BR></pre></TD></TR><TR BGCOLOR="#4492df"><TD><A NAME="_pod_AUTHOR"><B>AUTHOR</A></B></TD><TD><A HREF="#TOP">top</A></TD></TR><TR><TD COLSPAN="2"><pre>Ronan Oger, RO IT Systemms GmbH, <a href="mailto:ronan@roasp.com">ronan@roasp.com</a><BR></pre></TD></TR><TR BGCOLOR="#4492df"><TD><A NAME="_pod_CREDITS"><B>CREDITS</A></B></TD><TD><A HREF="#TOP">top</A></TD></TR><TR><TD COLSPAN="2"><pre>Peter Wainwright, <a href="mailto:peter@roasp.com">peter@roasp.com</a> Excellent ideas, beta-testing, SVG::Parser<BR>Fredo, <a href="http://www.penguin.at0.net/~fredo" target="urlWin">http://www.penguin.at0.net/~fredo</a>/ - provided initial feedback<BR>for early SVG.pm versions<BR>Adam Schneider, improvements to xmlescp providing improved character support<BR>Brial Pilpr⌨️ 快捷键说明
