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
