DmabufFormats

class DmabufFormats(pointer: <Error class: unknown class><<Error class: unknown class>>)

The GdkDmabufFormats struct provides information about supported DMA buffer formats.

You can query whether a given format is supported with method@Gdk.DmabufFormats.contains and you can iterate over the list of all supported formats with method@Gdk.DmabufFormats.get_n_formats and method@Gdk.DmabufFormats.get_format.

The list of supported formats is sorted by preference, with the best formats coming first.

The list may contains (format, modifier) pairs where the modifier is DMA_FORMAT_MOD_INVALID, indicating that implicit modifiers may be used with this format.

See class@Gdk.DmabufTextureBuilder for more information about DMA buffers.

Note that DMA buffers only exist on Linux.
