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
o new()
static methods
o ArrayRef getKnownFormats()
returns all formats known to gdk-pixbuf
o ArrayRef getSupportedFormats()
returns all formats you can store your svg image into
o bool isFormatSupported( String format )
returns true if you can store your image in this format else false
member methods
o 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
o 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.
o bool loadFromFile(String svgfile,[int dpi=0])
o bool loadFromFileAtZoom( String svgfile, double x_zoom, double y_zoom[, int dpi=0] )
o bool loadFromFileAtMaxSize( String svgfile, int width, int height[, int dpi=0] )
o bool loadFromFileAtSize( String svgfile, int width, int height[, int dpi=0] )
o bool loadFromFileAtZoomWithMax( String svgfile, double x_zoom, double y_zoom, int width, int height[, int dpi=0] )
o bool loadFromString(String svgfile,[int dpi=0])
o bool loadFromStringAtZoom( String svgfile, double x_zoom, double y_zoom[, int dpi=0] )
o bool loadFromStringAtMaxSize( String svgfile, int width, int height[, int dpi=0] )
o bool loadFromStringAtSize( String svgfile, int width, int height[, int dpi=0] )
o bool loadFromStringAtZoomWithMax( String svgfile, double x_zoom, double y_zoom, int width, int height[, int dpi=0] )
o bool convert( String svgfile, String bitmapfile[, int dpi=0, String format="png", int quality=100] )
o bool convertAtZoom( String svgfile, String bitmapfile, double x_zoom, double y_zoom[, int dpi=0, String format="png", int quality=100]
)
o bool convertAtMaxSize( String svgfile, String bitmapfile, int width, int height[, int dpi=0, String format="png", int quality=100] )
o bool convertAtSize( String svgfile, String bitmapfile, int width, int height[, int dpi=0, String format="png", int quality=100] )
o 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] )
o bool saveAs( String filename, [ String type, String quality ] )
Saves the image to a file
o 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
