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
