ABSTRACT

         This module provides an Perl-Interface towards the gnome-lib
         librsvg-2.

DESCRIPTION

       This module provides an Perl-Interface towards the gnome-lib librsvg-2 which is able to
       convert SVG(Scaleable Vector Graphics) into bitmapformats like (PNG,JPG,...). To which
       formats you can convert the svg-files depends on your gdk-pixbuf configuration. Still at
       least PNG and JPG should be available.

   EXPORT
       None by default.

   Methods
       Constructor

       ·   new()

       static methods

       ·   ArrayRef getKnownFormats()

           returns all formats known to gdk-pixbuf

       ·   ArrayRef getSupportedFormats()

           returns all formats you can store your svg image into

       ·   bool isFormatSupported( String format )

           returns true if you can store your image in this format else false

       member methods

       ·   bool loadImage( String svgfile[, int dpi=0, HashRef args] )

           This is function provides a common call mechanism to for all functions below, the
           args-variable can hold the following values:

           Case 1( = loadFromFile ):
                   undef

           Case 2( = loadFromFile ):
                   empty hashref

           Case 3( = loadFromFileAtZoom )
                   zoom->[0] ... x_zoom
                   zoom->[1] ... y_zoom

           Case 4( = loadFromFileAtMaxSize ):
                   dimension->[0] ... x-size
                   dimension->[1] ... y-size

           Case 5( = loadFromFileAtSize ):
                   dimension->[0] ... x-size
                   dimension->[1] ... y-size
                   dimension->[2] ... max-size-flag

           Case 6( = loadFromFileAtZoomWithMax ):
                   zoom->[0] ........ x_zoom
                   zoom->[1] ........ y_zoom
                   dimension->[0] ... x-size
                   dimension->[1] ... y-size

       ·   bool loadImageFromString( String svgfile[, int dpi=0, HashRef args] )

           Loads the image from an String containing a plain SVG. For information about args see
           loadImage.

       ·   bool loadFromFile(String svgfile,[int dpi=0])

       ·   bool loadFromFileAtZoom( String svgfile, double x_zoom, double y_zoom[, int dpi=0] )

       ·   bool loadFromFileAtMaxSize( String svgfile, int width, int height[, int dpi=0] )

       ·   bool loadFromFileAtSize( String svgfile, int width, int height[, int dpi=0] )

       ·   bool loadFromFileAtZoomWithMax( String svgfile, double x_zoom, double y_zoom, int
           width, int height[, int dpi=0] )

       ·   bool loadFromString(String svgfile,[int dpi=0])

       ·   bool loadFromStringAtZoom( String svgfile, double x_zoom, double y_zoom[, int dpi=0] )

       ·   bool loadFromStringAtMaxSize( String svgfile, int width, int height[, int dpi=0] )

       ·   bool loadFromStringAtSize( String svgfile, int width, int height[, int dpi=0] )

       ·   bool loadFromStringAtZoomWithMax( String svgfile, double x_zoom, double y_zoom, int
           width, int height[, int dpi=0] )

       ·   bool convert( String svgfile, String bitmapfile[, int dpi=0, String format="png", int
           quality=100] )

       ·   bool convertAtZoom( String svgfile, String bitmapfile, double x_zoom, double y_zoom[,
           int dpi=0, String format="png", int quality=100] )

       ·   bool convertAtMaxSize( String svgfile, String bitmapfile, int width, int height[, int
           dpi=0, String format="png", int quality=100] )

       ·   bool convertAtSize( String svgfile, String bitmapfile, int width, int  height[, int
           dpi=0, String format="png", int quality=100] )

       ·   bool convertAtZoomWithMax( String svgfile, String bitmapfile, double x_zoom, double
           y_zoom, int width, int height[, int dpi=0, String format="png", int quality=100] )

       ·   bool saveAs( String filename, [ String type, String quality ] )

           Saves the image to a file

       ·   SV getBitmap( [ String type, String quality ] )

           Saves the image to a scalar which can be passed on to other applications. This only
           return a useful value if you have compiled it with a gdk-pixbuf greater than or equal
           to 2.4
