#[repr(transparent)]
pub struct MetaBitmapRef { /* private fields */ }
Expand description

Bitmap information. This metadata contains a bitmap image in the given format and size. It is typically used for cursor images or other small images that are better transferred inline.

Implementations§

source§

impl MetaBitmapRef

source

pub fn format(&self) -> VideoFormat

bitmap video format, 0 is and invalid format should be handled as if there is no new bitmap information.

source

pub fn set_format(&mut self, format: VideoFormat)

source

pub fn size(&self) -> &RectangleRef

width and height of bitmap

source

pub fn size_mut(&mut self) -> &mut RectangleRef

source

pub fn stride(&self) -> i32

stride of bitmap data

source

pub fn set_stride(&mut self, stride: i32)

source

pub fn offset(&self) -> u32

offset of bitmap data in this structure. An offset of 0 means no image data (invisible), an offset >= sizeof(struct spa_meta_bitmap) contains valid bitmap info.

source

pub fn set_offset(&mut self, offset: u32)

source

pub unsafe fn bitmap<T: Sized>(&self) -> Option<&mut [T]>

Bitmap data with elements of type T. Returns [Some(&mut T)] or None, when bitmap data is missing.

Safety

There are no guarantees that bitmap has type T.

source

pub fn is_valid(&self) -> bool

impl RawWrapper for MetaBitmapRef

§

type CType = spa_meta_bitmap

External type
source§

fn as_raw_ptr(&self) -> *mut Self::CType

Raw ptr to the external type
source§

fn as_raw(&self) -> &Self::CType

Wrapped external value
source§

fn from_raw(raw: Self::CType) -> Self

Creates wrapper from the external value, can be use when external type has no raw pointers.
source§

unsafe fn mut_from_raw_ptr<'lft>(raw: *mut Self::CType) -> &'lft mut Self
