Functions

rsvg_handle_set_base_gfile ()

void
rsvg_handle_set_base_gfile (RsvgHandle *handle,
                            GFile *base_file);

Set the base URI for handle from file . Note: This function may only be called before rsvg_handle_write() or rsvg_handle_read_stream_sync() has been called.

Parameters

handle

a RsvgHandle

 

base_file

a GFile

 

Since 2.32


rsvg_handle_read_stream_sync ()

gboolean
rsvg_handle_read_stream_sync (RsvgHandle *handle,
                              GInputStream *stream,
                              GCancellable *cancellable,
                              GError **error);

Reads stream and writes the data from it to handle .

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

Parameters

handle

a RsvgHandle

 

stream

a GInputStream

 

cancellable

a GCancellable, or NULL.

[allow-none]

error

a location to store a GError, or NULL.

[allow-none]

Returns

TRUE if reading stream succeeded, or FALSE otherwise with error filled in

rsvg_handle_new_from_gfile_sync (GFile *file,
                                 RsvgHandleFlags flags,
                                 GCancellable *cancellable,
                                 GError **error);

Creates a new RsvgHandle for file .

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

Parameters

RsvgHandle *
rsvg_handle_new_from_stream_sync (GInputStream *input_stream,
                                  GFile *base_file,
                                  RsvgHandleFlags flags,
                                  GCancellable *cancellable,
                                  GError **error);

Creates a new RsvgHandle for stream .

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

Parameters

input_stream

a GInputStream

 

base_file

a GFile, or NULL.

[allow-none]

flags

flags from RsvgHandleFlags

 

cancellable

a GCancellable, or NULL.

[allow-none]

error
