}

The current configuration for accessibility color transforms, which includes color inversion and color correction. This always includes the matrix required to apply the appropriate transforms. Color correction and color inversion may be active simultaneously.

For original RGB value (r, g, b) (each component ranged between 0 and 1), the RGB value of corrected color (r’, g’, b’) is (r’, g’, b’) = color_adjustment_post_offset + color_adjustment_matrix . ((r, g, b) + color_adjustment_pre_offset).

Fields

color_inversion_enabled: Option<bool>

When color_inversion_enabled is true, certain colors are inverted across the entire screen. If this field is omitted behavior should remain unchanged.

color_correction: Option<ColorCorrectionMode>

When color_correction is set to DISABLED, colors are displayed normally. When color_correction has different value, colors are modified to correct for the specified type of color blindness. If this field is omitted behavior should remain unchanged.

color_adjustment_matrix: Option<[f32; 9]>

3x3 Matrix in row-major form which will be used by root presenter to apply color correction and color inversion, or a combination fo the two. This field should always be set.

color_adjustment_pre_offset: Option<[f32; 3]>

3x1 vector which is used by root presenter as an offset added to the original RGB color, before it multiplies with the |color_adjustment_matrix|. This field should always be set.

color_adjustment_post_offset: Option<[f32; 3]>

3x1 vector which is used by root presenter as an offset added to the multiplied result of |color_adjustment_matrix| and original RGB color. This field should always be set.

Trait Implementations

impl Clone for ColorTransformConfiguration

fn clone(&self) -> ColorTransformConfiguration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColorTransformConfiguration

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

Formats the value using the given formatter.

impl Decode<ColorTransformConfiguration> for ColorTransformConfiguration

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

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

Decodes an object of type T from the decoder’s buffers into self.

impl Default for ColorTransformConfiguration

fn default() -> ColorTransformConfiguration

Returns the “default value” for a type.

impl Encode<ColorTransformConfiguration> for &ColorTransformConfiguration

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

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for ColorTransformConfiguration

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

impl TypeMarker for ColorTransformConfiguration

type Owned = ColorTransformConfiguration

The owned Rust type which this FIDL type decodes into.

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 alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for ColorTransformConfiguration

type Borrowed<'a> = &'a ColorTransformConfiguration

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

Cheaply converts from &Self::Owned to Self::Borrowed.
