Struct fidl_fuchsia_ui_display_color::ConversionProperties

pub struct ConversionProperties {
    pub coefficients: Option<[f32; 9]>,
    pub preoffsets: Option<[f32; 3]>,
    pub postoffsets: Option<[f32; 3]>,
    /* private fields */
}

The properties required to apply color conversion to the display. The conversion is applied to each pixel of the display according to the formula:

[coefficients * (pixel + preoffsets) + postoffsets].

where pixel is a column vector consisting of the pixel’s 3 RGB components.

Fields

coefficients: Option<[f32; 9]>

The |coefficients| param represents a 3x3 matrix, where the values are given in row-major order:

| 0 1 2 | | 3 4 5 | | 6 7 8 |

preoffsets: Option<[f32; 3]>

Preoffsets and postoffsets represent a [3x1] vector each of RGB values.

postoffsets: Option<[f32; 3]>

Implementations

impl ConversionProperties

pub const EMPTY: Self = _

An empty table with every field set to None.

Trait Implementations

impl Clone for ConversionProperties

fn clone(&self) -> ConversionProperties

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConversionProperties

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

Formats the value using the given formatter.

impl Decodable for ConversionProperties

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

fn decode(&mut self, decoder: &mut Decoder<'_>, offset: usize) -> Result<()>

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for ConversionProperties

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<()>

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

impl Layout for ConversionProperties

fn inline_align(_context: &Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: &Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl PartialEq<ConversionProperties> for ConversionProperties

fn eq(&self, other: &ConversionProperties) -> 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.
