枚举 SwsIntent 

#[repr(i32)]
pub enum SwsIntent {
    SWS_INTENT_PERCEPTUAL = 0,
    SWS_INTENT_RELATIVE_COLORIMETRIC = 1,
    SWS_INTENT_SATURATION = 2,
    SWS_INTENT_ABSOLUTE_COLORIMETRIC = 3,
    SWS_INTENT_NB = 4,
}

Variants

SWS_INTENT_PERCEPTUAL = 0

< Perceptual tone mapping

SWS_INTENT_RELATIVE_COLORIMETRIC = 1

< Relative colorimetric clipping

SWS_INTENT_SATURATION = 2

< Saturation mapping

SWS_INTENT_ABSOLUTE_COLORIMETRIC = 3

< Absolute colorimetric clipping

SWS_INTENT_NB = 4

< not part of the ABI
