Enum JxlBitDepthType 

#[repr(i32)]
pub enum JxlBitDepthType {
    FromPixelFormat = 0,
    FromCodestream = 1,
    Custom = 2,
}

Settings for the interpretation of UINT input and output buffers. (buffers using a FLOAT data type are not affected by this)

Variants

FromPixelFormat = 0

This is the default setting, where the encoder expects the input pixels to use the full range of the pixel format data type (e.g. for UINT16, the input range is 0 .. 65535 and the value 65535 is mapped to 1.0 when converting to float), and the decoder uses the full range to output pixels. If the bit depth in the basic info is different from this, the encoder expects the values to be rescaled accordingly (e.g. multiplied by 65535/4095 for a 12-bit image using UINT16 input data type).

FromCodestream = 1

If this setting is selected, the encoder expects the input pixels to be in the range defined by the JxlBasicInfo::bits_per_sample value (e.g. for 12-bit images using UINT16 input data types, the allowed range is 0 .. 4095 and the value 4095 is mapped to 1.0 when converting to float), and the decoder outputs pixels in this range.

Custom = 2

This setting can only be used in the decoder to select a custom range for pixel output.

Trait Implementations

impl Clone for JxlBitDepthType

fn clone(&self) -> JxlBitDepthType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JxlBitDepthType

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

Formats the value using the given formatter.

impl Hash for JxlBitDepthType

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,

impl PartialEq for JxlBitDepthType

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