impl Surface[src]

pub unsafe fn get_mime_data_raw(&self, mime_type: &str) -> Option<&[u8]>[src]

pub fn set_mime_data<T: AsRef<[u8]> + 'static>(
    &self,
    mime_type: &str,
    slice: T
) -> Result<(), Error>
[src]

pub fn supports_mime_type(&self, mime_type: &str) -> bool[src]

[src]

pub fn create_similar_image(
    &self,
    format: Format,
    width: i32,
    height: i32
) -> Result<Surface, Error>
[src]

pub fn map_to_image(
    &self,
    extents: Option<RectangleInt>

[src]

pub fn mark_dirty(&self)[src]

pub fn mark_dirty_rectangle(&self, x: i32, y: i32, width: i32, height: i32)[src]

pub fn set_user_data<T: 'static>(
    &self,
    key: &'static UserDataKey<T>,
    value: Rc<T>
)
[src]

Attach user data to self for the given key.

pub fn get_user_data<T: 'static>(
    &self,
    key: &'static UserDataKey<T>
) -> Option<Rc<T>>
[src]

Return the user data previously attached to self with the given key, if any.

pub fn get_user_data_ptr<T: 'static>(
    &self,
    key: &'static UserDataKey<T>
) -> Option<NonNull<T>>
[src]

Return the user data previously attached to self with the given key, if any, without incrementing the reference count.

The pointer is valid when it is returned from this method, until the cairo object that self represents is destroyed or remove_user_data or set_user_data is called with the same key.

pub fn remove_user_data<T: 'static>(&self, key: &'static UserDataKey<T>)[src]

Unattach from self the user data associated with key, if any. If there is no other Rc strong reference, the data is destroyed.

impl Surface[src]

pub fn flush(&self)[src]

pub fn finish(&self)[src]

pub fn get_type(&self) -> SurfaceType[src]

impl Surface[src]

pub fn finish_output_stream(&self) -> Result<Box<dyn Any>, StreamWithError>[src]

Finish the surface, then remove and return the output stream if any.

This calls Surface::finish, to make sure pending writes are done.

This is relevant for surfaces created for example with [PdfSurface::for_stream].

Use Box::downcast to recover the concrete stream type.

Panics

This method panics if:

  • This method was already called for this surface, or
  • This surface was not created with an output stream in the first place, or
  • A previous write to this surface panicked, or
  • A previous write happened while another write was ongoing, or
  • A write is ongoing now.

The latter two cases can only occur with a pathological output stream type that accesses the same surface again from Write::write_all.
