## Description

GdkPixbuf is a library for image loading and manipulation. It is part of the cross-platform GTK+ widget toolkit.

## Details

### rsvg_handle_get_pixbuf ()

    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`.

### rsvg_handle_get_pixbuf_sub ()

    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. For example, if you have a layer called "layer1" that you wish to render, pass "#layer1" as the id.
Returns : | the pixbuf loaded by handle, or `NULL`.

Since 2.14

### rsvg_pixbuf_from_file ()

    GdkPixbuf*          rsvg_pixbuf_from_file               (const gchar *file_name,
                                                             GError **error);

### Warning

`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`

### rsvg_pixbuf_from_file_at_zoom ()

    GdkPixbuf*          rsvg_pixbuf_from_file_at_zoom       (const gchar *file_name,
                                                             double x_zoom,
                                                             double y_zoom,
                                                             GError **error);

### Warning

`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`

### rsvg_pixbuf_from_file_at_size ()

    GdkPixbuf*          rsvg_pixbuf_from_file_at_size       (const gchar *file_name,
                                                             gint width,
                                                             gint height,
                                                             GError **error);

### Warning

`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`

### rsvg_pixbuf_from_file_at_max_size ()

    GdkPixbuf*          rsvg_pixbuf_from_file_at_max_size   (const gchar *file_name,
                                                             gint max_width,
                                                             gint max_height,
                                                             GError **error);

### Warning

`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`

### rsvg_pixbuf_from_file_at_zoom_with_max ()

    GdkPixbuf*          rsvg_pixbuf_from_file_at_zoom_with_max
                                                            (const gchar *file_name,

                                                             double y_zoom,
                                                             gint max_width,
                                                             gint max_height,
                                                             GError **error);

### Warning

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` : | return location for errors
Returns : | A newly allocated GdkPixbuf, or `NULL`
