Abstract

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

Overview

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
