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
