pub struct ImageSurface(_);

Implementations

Creates an image surface for the provided pixel data.

  • The pointer data is the beginning of the underlying slice, and at least width * stride succeeding bytes should be allocated.
  • data must live longer than any reference to the returned surface.
  • You have to free data by yourself.

Methods from Deref<Target = Surface>

Attach user data to self for the given key.

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

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.

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