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

Since: 2.32


rsvg_handle_new_from_gfile_sync ()

RsvgHandle *
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

file

a GFile

 

flags

flags from RsvgHandleFlags

 

cancellable

a GCancellable, or NULL.

[allow-none]

error

a location to store a GError, or NULL.

[allow-none]

Returns

a new RsvgHandle on success, or NULL with error filled in

Since: 2.32


rsvg_handle_new_from_stream_sync ()

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

RSVG_HANDLE_FLAG_UNLIMITED

Disable safety limits in the XML parser. Libxml2 has several limits designed to keep malicious XML content from consuming too much memory while parsing. For security reasons, this should only be used for trusted input! Since: 2.40.3

 

RSVG_HANDLE_FLAG_KEEP_IMAGE_DATA

Use this if the Cairo surface to which you are rendering is a PDF, PostScript, SVG, or Win32 Printing surface. This will make librsvg and Cairo use the original, compressed data for images in the final output, instead of passing uncompressed images. This will make a Keeps the image data when loading images, for use by cairo when painting to e.g. a PDF surface. For example, this will make the a resulting PDF file smaller and faster. Please see the Cairo documentation for details. Since: 2.40.3
