Struct re_types::datatypes::ImageFormat

pub struct ImageFormat {
    pub width: u32,
    pub height: u32,
    pub pixel_format: Option<PixelFormat>,
    pub color_model: Option<ColorModel>,
    pub channel_datatype: Option<ChannelDatatype>,
}

Datatype: The metadata describing the contents of a components::ImageBuffer.

Fields

width: u32

The width of the image in pixels.

height: u32

The height of the image in pixels.

pixel_format: Option<PixelFormat>

Used mainly for chroma downsampled formats and differing number of bits per channel.

If specified, this takes precedence over both datatypes::ColorModel and datatypes::ChannelDatatype (which are ignored).

color_model: Option<ColorModel>

L, RGB, RGBA, …

Also requires a datatypes::ChannelDatatype to fully specify the pixel format.

channel_datatype: Option<ChannelDatatype>

The data type of each channel (e.g. the red channel) of the image data (U8, F16, …).

Also requires a datatypes::ColorModel to fully specify the pixel format.

Immutably borrows from an owned value.

impl Clone for ImageFormat

fn clone(&self) -> ImageFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ImageFormat

fn default() -> ImageFormat

Returns the “default value” for a type.

impl<'a> From<&'a ImageFormat> for Cow<'a, ImageFormat>

fn from(value: &'a ImageFormat) -> Self

Converts to this type from the input type.

impl<'a> From<ImageFormat> for Cow<'a, ImageFormat>

fn from(value: ImageFormat) -> Self

Converts to this type from the input type.

impl Hash for ImageFormat

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Loggable for ImageFormat

type Name = DatatypeName

fn name() -> Self::Name

The fully-qualified name of this loggable, e.g. rerun.datatypes.Vec2D.

fn arrow_datatype() -> DataType

The underlying [arrow2::datatypes::DataType], excluding datatype extensions.

fn to_arrow_opt<'a>( data: impl IntoIterator<Item = Option<impl Into<Cow<'a, Self>>>> ) -> SerializationResult<Box<dyn Array>>

where Self: Clone + 'a,

Given an iterator of options of owned or reference values to the current Loggable, serializes them into an Arrow array.

fn from_arrow_opt( arrow_data: &dyn Array ) -> DeserializationResult<Vec<Option<Self>>>

where Self: Sized,

Given an Arrow array, deserializes it into a collection of optional Loggables.

fn to_arrow<'a>( data: impl IntoIterator<Item = impl Into<Cow<'a, Self>>> ) -> Result<Box<dyn Array>, SerializationError>

where Self: 'a,

impl PartialEq for ImageFormat

fn eq(&self, other: &ImageFormat) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
