Struct Raw1Image

pub struct Raw1Image {
    pub indexed_rgb: Vec<u8>,
    pub indexed_alpha: Vec<u8>,
}

Fields

indexed_rgb: Vec<u8>

BGR component values can be obtained by using indexedRGB values as an index in lutBGR. When producing such values using color matching be aware of the linear nature of the color space. For best results it is recommended that color matching be performed in sRGB or other perceptual color spaces.

indexed_alpha: Vec<u8>

Alpha component can be obtained by breaking indexedAlpha into a bit field of alphaBits bit length fragments and then using the bit fragment as the alpha value for the pixel. The alpha pixel components are ordered from least significant to most significant bit with bytes following the same pixel order as indexedRGB. Since the alpha is to alphaBits precision it may need to be resampled to 8 bits be useful depending on the imaging framework used.

Example of different alpha packing in a byte:

MSB <-> LSB where number indicates the sequential pixel the bits belong to
ALPHA_8B -> 11111111
ALPHA_4B -> 22221111
ALPHA_1B -> 87654321

Implementations

Trait Implementations

impl Clone for Raw1Image

fn clone(&self) -> Raw1Image

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Raw1Image

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

Formats the value using the given formatter.

impl Hash for Raw1Image

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Raw1Image

fn cmp(&self, other: &Raw1Image) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Raw1Image

fn eq(&self, other: &Raw1Image) -> 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 PartialOrd for Raw1Image

fn partial_cmp(&self, other: &Raw1Image) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
