Enum png::common::SrgbRenderingIntent

#[repr(u8)]
pub enum SrgbRenderingIntent {
    Perceptual = 0,
    RelativeColorimetric = 1,
    Saturation = 2,
    AbsoluteColorimetric = 3,
}

The rendering intent for an sRGB image.

Presence of this data also indicates that the image conforms to the sRGB color space.

Variants

Perceptual = 0

For images preferring good adaptation to the output device gamut at the expense of colorimetric accuracy, such as photographs.

RelativeColorimetric = 1

For images requiring colour appearance matching (relative to the output device white point), such as logos.

Saturation = 2

For images preferring preservation of saturation at the expense of hue and lightness, such as charts and graphs.

AbsoluteColorimetric = 3

For images requiring preservation of absolute colorimetry, such as previews of images destined for a different output device (proofs).

Implementations

impl SrgbRenderingIntent

pub(crate) fn into_raw(self) -> u8

pub(crate) fn from_raw(raw: u8) -> Option<Self>

pub fn encode<W: Write>(self, w: &mut W) -> Result<(), EncodingError>

Trait Implementations

impl Clone for SrgbRenderingIntent

fn clone(&self) -> SrgbRenderingIntent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SrgbRenderingIntent

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

Formats the value using the given formatter.

impl PartialEq for SrgbRenderingIntent

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