Interface

AtkImage

Description [src]

interface Atk.Image : GObject.Object

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.

Prerequisite

In order to implement Image, your type must inherit from GObject.

Instance methods

atk_image_get_image_description

Get a textual description of this image.

atk_image_get_image_locale

Retrieves the locale identifier associated to the AtkImage.

Available since: 1.12

atk_image_get_image_position

Gets the position of the image in the form of a point specifying the images top-left corner.

atk_image_get_image_size

Get the width and height in pixels for the specified image. The values of width and height are returned as -1 if the values cannot be obtained (for instance, if the object is not onscreen).

atk_image_set_image_description

Sets the textual description for this image.
