+
+SVG:SVG2zinc::Backend::Image - a backend class for generating image file from SVG file
+
+=head1 DESCRIPTION
+
+SVG:SVG2zinc::Backend::Image is a backend class for generating image file from SVG files. It uses the 'import' command included in the ImageMagick package.
+
+For more information, you should look at SVG:SVG2zinc::Backend(3pm).
+
+The new method accepts parameters described in the SVG:SVG2zinc::Backend class and the following additionnal parameters:
+
+=over
+
+=item B<none>
+
+=back
+
+=head1 SEE ALSO
+
+SVG::SVG2zinc::Backend(3pm) and SVG::SVG2zinc(3pm)
+
+=head1 BUGS and LIMITATIONS
+
+This backend generates images files from the content of a displayed Tk::Zinc window. The size (in pixels) of the generated image is thus limited to the maximal size of a window on your system.

+=head1 NAME
+
+SVG:SVG2zinc::Backend::PerlScript - a backend class generating Perl script displaying the content of a SVG file
+
+=head1 SYNOPSIS
+
+ use SVG:SVG2zinc::Backend::PerlScript;
+
+ $backend = SVG:SVG2zinc::Backend::PerlScript->new(
+	       -out => filename_or_handle,
+               -in => svgfilename,
+	       -verbose => 0|1,
+	       -render => 0|1|2,
+	       );
+
+ $backend->fileHeader();
+
+ $backend->treatLines("lineOfCode1", "lineOfCode2",...);
+
+ $backend->comment("comment1", "comment2", ...);
+
+ $backend->printLines("comment1", "comment2", ...);
+
+ $backend->fileTail();
+
+=head1 DESCRIPTION
+
+SVG:SVG2zinc::Backend::PerlScript is a class for generating perl script which displays the content of a SVG file. The generated script requires Tk::Zinc.
+
+For more information, you should look at SVG::SVG2zinc::Backend(3pm).
+
+The generated perl script uses the Tk::Zinc::Debug tool, so it is easy to inspect items created in Tk::Zinc. Use the <ESC> key to get some help when the cursor is in the Tk::Zinc window. 
+
+The B<new> method accepts parameters described in the SVG:SVG2zinc::Backend class and the following additionnal parameter:
+
+=over
+
+=item B<-render>
+
+The render option of the Tk::Zinc widget. A value of 0 means no openGL, 1 or 2 for openGL. Defaults to 1.

+=head1 DESCRIPTION
+
+SVG:SVG2zinc::Backend::TclScript is a class for generating Tcl script to display SVG files. The generated script is based on TkZinc.
+
+For more information, you should look at SVG:SVG2zinc::Backend(3pm).
+
+The new method accepts parameters described in the SVG:SVG2zinc::Backend class and the following additionnal parameters:
+
+=over
+
+=item B<-render>
+
+The render value of the TkZinc widget. 0 means no openGL, 1 or 2 for openGL. Defaults to 1.

+
+=head1 BUGS and LIMITATIONS
+
+This is higly experimental. Only few tests... The author is not a Tcl coder!
+
+The Tk::Zinc::SVGExtension perl module provided with SVG::SVG2zinc should be converted in Tcl and imported by (or included in) the generated Tcl script.
