Enum png::SrgbRenderingIntent

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

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).
