Class (GI Struct)

Gdk-4.0 ▶ Gdk ▶ DmabufFormatsAbstractSince 4.14

Provides information about supported DMA buffer formats.

You can query whether a given format is supported with Gdk.DmabufFormats.contains and you can iterate over the list of all supported formats with Gdk.DmabufFormats.get_n_formats and 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 Gdk.DmabufTextureBuilder for more information about DMA buffers.

Note that DMA buffers only exist on Linux.

  • Returns whether a given format is contained in formats.

    Parameters

    • fourcc: number

      a format code

    • modifier: number | bigint

      a format modifier

    Returns boolean

    TRUE if the format specified by the arguments is part of formats

    4.14

  • Gets the fourcc code and modifier for a format that is contained in formats.

    Parameters

    • idx: number | bigint

      the index of the format to return

    Returns [number, number]

    4.14

  • Returns the number of formats that the formats object contains.

    Note that DMA buffers are a Linux concept, so on other platforms, Gdk.DmabufFormats.get_n_formats will always return zero.

    Returns number

    the number of formats

    4.14

  • Decreases the reference count of formats.

    When the reference count reaches zero, the object is freed.

    Returns void
