NAME¶

Image::LibRSVG - Perl extension for librsvg

SYNOPSIS¶

  use Image::LibRSVG;
  
  ## static Methods
  my $known_formats = Image::LibRSVG->getKnownFormats();
  my $formats       = Image::LibRSVG->getSupportedFormats();
  my $isSupported   = Image::LibRSVG->isFormatSupported("tiff");
  
  my $rsvg = new Image::LibRSVG();
  
  $rsvg->convert("my.svg", "my.png" );
  $rsvg->convertAtZoom("my.svg", "my.png", 1.5, 1.5 );
  $rsvg->convertAtMaxSize("my.svg", "my.png", 200, 300 );
  $rsvg->convertAtSize("my.svg", "my.png", 200, 300 );
  $rsvg->convertAtZoomWithMax("my.svg", "my.png", 1.5, 1.5, 200, 300 );
  
  $formats     = $rsvg->getSupportedFormats();
  $isSupported = $rsvg->isFormatSupported("tiff");
  
  $rsvg->loadImage( "my.svg" );
  
  open( SVGFILE, "< my.svg" );
  local( $/ ) ;
  $rsvg->loadImageFromString( <SVGFILE> );
  close SVGFILE;
  
  $rsvg->saveAs( "my.png" );
  $rsvg->saveAs( "my.jpg", "jpeg" );
  
  $rsvg->loadImage( "my.svg", 0, { zoom => [ 1.5, 1.5 ] } );
  $rsvg->saveAs( "zoomed.png" );
  
  my $bitmap = $rsvg->getImageBitmap();

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:

•

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
