Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Default = 0

Default colorspace, i.e. let the driver figure it out. Can only be used with video capture.

Smpte170M = 1

SMPTE 170M: used for broadcast NTSC/PAL SDTV

Smpte240M = 2

Obsolete pre-1998 SMPTE 240M HDTV standard, superseded by Rec 709

Rec709 = 3

Rec.709: used for HDTV

Bt878 = 4

Deprecated, do not use. No driver will ever return this. This was based on a misunderstanding of the bt878 datasheet.

C470SystemM = 5

NTSC 1953 colorspace. This only makes sense when dealing with really, really old NTSC recordings. Superseded by SMPTE 170M.

C470SystemBg = 6

EBU Tech 3213 PAL/SECAM colorspace.

Jpeg = 7

Effectively shorthand for SRGB, YCBCR_ENC_601 and QUANTIZATION_FULL_RANGE. To be used for (Motion-)JPEG.

Srgb = 8

For RGB colorspaces such as produces by most webcams.

Oprgb = 9

opRGB colorspace

Bt2020 = 10

BT.2020 colorspace, used for UHDTV.

Raw = 11

Raw colorspace: for RAW unprocessed images

DciP3 = 12

DCI-P3 colorspace, used by cinema projectors

Implementations

impl ColorSpace

pub fn new_default(is_sdtv: bool, is_hdtv: bool) -> Self

Determine how ColorSpace::Default should map to a proper colorspace. This depends on whether this is a SDTV image (use SMPTE 170M), an HDTV image (use Rec. 709), or something else (use sRGB).

Methods from Deref<Target = u32>

pub const BITS: u32 = 32u32

Trait Implementations

impl AsRef<u32> for ColorSpace

fn as_ref(&self) -> &u32

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ColorSpace

fn clone(&self) -> ColorSpace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorSpace

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

Formats the value using the given formatter.

impl Deref for ColorSpace

type Target = u32

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for ColorSpace

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

Formats the value using the given formatter.

impl From<ColorSpace> for XferFunc

fn from(colsp: ColorSpace) -> Self

Determine how XferFunc::Default should map to a proper transfer function. This depends on the colorspace.

impl From<ColorSpace> for YcbcrEncoding

fn from(colsp: ColorSpace) -> Self

Determine how YcbcrEncoding::Default should map to a proper Y’CbCr encoding. This depends on the colorspace.

impl From<ColorSpace> for u32

fn from(data: ColorSpace) -> Self

Converts to this type from the input type.

impl From<FourCc> for ColorSpace

fn from(pixfmt: FourCc) -> Self

Converts to this type from the input type.

impl PartialEq for ColorSpace

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<u32> for ColorSpace

type Error = u32

The type returned in the event of a conversion error.

fn try_from(data: u32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ColorSpace

impl Eq for ColorSpace

impl StructuralPartialEq for ColorSpace
