GdkPixbuf is a library for image loading and manipulation. It is part of the cross-platform GTK+ widget toolkit.
GdkPixbuf* rsvg_handle_get_pixbuf (RsvgHandle *handle);
Returns the pixbuf loaded by handle. The pixbuf returned will be reffed, so
the caller of this function must assume that ref. If insufficient data has
been read to create the pixbuf, or an error occurred in loading, then NULL
will be returned. Note that the pixbuf may not be complete until
rsvg_handle_close has been called.
handle : |
An RsvgHandle |
| Returns : | the pixbuf loaded by handle, or NULL.
|
GdkPixbuf* rsvg_handle_get_pixbuf_sub (RsvgHandle *handle,
const char *id);
Returns the pixbuf loaded by handle. The pixbuf returned will be reffed, so
the caller of this function must assume that ref. If insufficient data has
been read to create the pixbuf, or an error occurred in loading, then NULL
will be returned. Note that the pixbuf may not be complete until
rsvg_handle_close has been called.
handle : |
An RsvgHandle |
id : |
The id of an element inside the SVG, or NULL to render the whole SVG
|
| Returns : | the pixbuf loaded by handle, or NULL.

Since 2.14
GdkPixbuf* rsvg_pixbuf_from_file (const gchar *file_name,
GError **error);
rsvg_pixbuf_from_file is deprecated and should not be used in newly-written code. Set up a cairo matrix and use rsvg_handle_new_from_file() + rsvg_handle_render_cairo() instead.
Loads a new GdkPixbuf from file_name and returns it. The caller must
assume the reference to the reurned pixbuf. If an error occurred, error is
set and NULL is returned.
file_name : |
A file name |
error : |
return location for errors |
| Returns : | A newly allocated GdkPixbuf, or NULL
|
GdkPixbuf* rsvg_pixbuf_from_file_at_zoom (const gchar *file_name,
double x_zoom,
double y_zoom,
GError **error);
rsvg_pixbuf_from_file_at_zoom is deprecated and should not be used in newly-written code. Set up a cairo matrix and use rsvg_handle_new_from_file() + rsvg_handle_render_cairo() instead.
Loads a new GdkPixbuf from file_name and returns it. This pixbuf is scaled
from the size indicated by the file by a factor of x_zoom and y_zoom. The
caller must assume the reference to the returned pixbuf. If an error
occurred, error is set and NULL is returned.
file_name : |
A file name |
x_zoom : |
The horizontal zoom factor |
y_zoom : |
The vertical zoom factor |
error : |
return location for errors |
| Returns : | A newly allocated GdkPixbuf, or NULL
|
GdkPixbuf* rsvg_pixbuf_from_file_at_size (const gchar *file_name,
gint width,
gint height,
GError **error);
rsvg_pixbuf_from_file_at_size is deprecated and should not be used in newly-written code. Set up a cairo matrix and use rsvg_handle_new_from_file() + rsvg_handle_render_cairo() instead.
Loads a new GdkPixbuf from file_name and returns it. This pixbuf is scaled
from the size indicated to the new size indicated by width and height. If
either of these are -1, then the default size of the image being loaded is
used. The caller must assume the reference to the returned pixbuf. If an
error occurred, error is set and NULL is returned.
file_name : |
A file name |
width : |
The new width, or -1 |
height : |
The new height, or -1 |
error : |
return location for errors |
| Returns : | A newly allocated GdkPixbuf, or NULL
|
GdkPixbuf* rsvg_pixbuf_from_file_at_max_size
(const gchar *file_name,
gint max_width,
gint max_height,
GError **error);
rsvg_pixbuf_from_file_at_max_size is deprecated and should not be used in newly-written code. Set up a cairo matrix and use rsvg_handle_new_from_file() + rsvg_handle_render_cairo() instead.
Loads a new GdkPixbuf from file_name and returns it. This pixbuf is uniformly
scaled so that the it fits into a rectangle of size max_width * max_height. The
caller must assume the reference to the returned pixbuf. If an error occurred,
error is set and NULL is returned.
file_name : |
A file name |
max_width : |
The requested max width |
max_height : |
The requested max heigh |
error : |
return location for errors |
| Returns : | A newly allocated GdkPixbuf, or NULL
|
GdkPixbuf* rsvg_pixbuf_from_file_at_zoom_with_max
(const gchar *file_name,
double x_zoom,
double y_zoom,
gint max_width,
gint max_height,
GError **error);
rsvg_pixbuf_from_file_at_zoom_with_max is deprecated and should not be used in newly-written code. Set up a cairo matrix and use rsvg_handle_new_from_file() + rsvg_handle_render_cairo() instead.
Loads a new GdkPixbuf from file_name and returns it. This pixbuf is scaled
from the size indicated by the file by a factor of x_zoom and y_zoom. If the
resulting pixbuf would be larger than max_width/max_heigh it is uniformly scaled
down to fit in that rectangle. The caller must assume the reference to the
returned pixbuf. If an error occurred, error is set and NULL is returned.
file_name : |
A file name |
x_zoom : |
The horizontal zoom factor |
y_zoom : |
The vertical zoom factor |
max_width : |
The requested max width |
max_height : |
The requested max heigh |
error : |
