ImageRef
public struct ImageRef : ImageProtocol
AtkImage
should be implemented by AtkObject
subtypes on behalf of
components which display image/pixmap information onscreen, and
which provide information (other than just widget borders, etc.)
via that image content. For instance, icons, buttons with icons,
toolbar elements, and image viewing panes typically should
implement AtkImage
.
AtkImage
primarily provides two types of information: coordinate
information (useful for screen review mode of screenreaders, and
for use by onscreen magnifiers), and descriptive information. The
descriptive information is provided for alternative, text-only
presentation of the most significant information present in the
image.
The ImageRef
type acts as a lightweight Swift reference to an underlying AtkImage
instance.
It exposes methods that can operate on this data type through ImageProtocol
conformance.
Use ImageRef
only as an unowned
reference to an existing AtkImage
instance.

Untyped pointer to the underlying `AtkImage` instance.

image_ptr
property instead.Declaration
