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: 

  •     undef

  •     empty hashref

  •     zoom->[0] ... x_zoom
    zoom->[1] ... y_zoom

  •     dimension->[0] ... x-size
    dimension->[1] ... y-size

  •     dimension->[0] ... x-size
    dimension->[1] ... y-size
    dimension->[2] ... max-size-flag

  •     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
