rsvg_handle_new ()

RsvgHandle *
rsvg_handle_new (void);

Returns a new rsvg handle. Must be freed with g_object_unref . This handle can be used for dynamically loading an image. You need to feed it data using rsvg_handle_write , then call rsvg_handle_close when done. Afterwords, you can render it using Cairo or get a GdkPixbuf from it. When finished, free with g_object_unref(). No more than one image can be loaded with one handle.

rsvg_handle_new_with_flags ()

RsvgHandle *
rsvg_handle_new_with_flags (RsvgHandleFlags flags);

Creates a new RsvgHandle with flags flags .

Since: 2.36

rsvg_handle_write ()

gboolean

                   gsize count,
                   GError **error);

Loads the next count bytes of the image. This will return TRUE if the data was loaded successful, and FALSE if an error occurred. In the latter case, the loader will be closed, and will not accept further writes. If FALSE is returned, error will be set to an error from the RsvgError domain. Errors from GIOErrorEnum are also possible.

rsvg_handle_close ()

gboolean
rsvg_handle_close (RsvgHandle *handle,
                   GError **error);

void
render_scaled_proportionally (RsvgHandle *handle, cairo_t cr, int width, int height)
{
    RsvgDimensionData dimensions;
    double x_factor, y_factor;
    double scale_factor;

    rsvg_handle_get_dimensions (handle, &dimensions);

    x_factor = (double) width / dimensions.width;
    y_factor = (double) height / dimensions.height;

    scale_factor = MIN (x_factor, y_factor);

    cairo_scale (cr, scale_factor, scale_factor);

    rsvg_handle_render_cairo (handle, cr);
}

The size of the image is passed in to the function, which may then modify these values to set the real size of the generated pixbuf. If the image has no associated size, then the size arguments are set to -1.
