Struct DecodedImageF32 

#[non_exhaustive]
pub struct DecodedImageF32 {
    pub width: u32,
    pub height: u32,
    pub format: PixelFormat,
    pub data: Vec<f32>,
}

A decoded image with 32-bit floating point pixel data.

This preserves the full 12-bit internal precision of jpegli’s decoder without quantization to 8-bit. Values are in the range 0.0-1.0.

Use this format when you need:

• Maximum precision for further image processing
• HDR workflows
• Scientific/medical imaging applications
• Input to machine learning models

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

width: u32

Image width in pixels

height: u32

Image height in pixels

format: PixelFormat

Pixel format of the data

data: Vec<f32>

Float pixel data in range 0.0-1.0

Implementations

impl DecodedImageF32

pub fn dimensions(&self) -> (u32, u32)

Returns the image dimensions as a tuple (width, height).

pub fn channels(&self) -> usize

Returns the number of channels for this image’s format.

pub fn stride(&self) -> usize

Returns the stride (floats per row) of the image.

pub fn to_u8(&self) -> DecodedImage

Converts to 8-bit integer format.

Values are scaled from 0.0-1.0 to 0-255 and clamped.

pub fn to_u16(&self) -> Vec<u16>

Converts to 16-bit integer format.

Values are scaled from 0.0-1.0 to 0-65535 and clamped.

Trait Implementations

impl Clone for DecodedImageF32

fn clone(&self) -> DecodedImageF32

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodedImageF32

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

Formats the value using the given formatter.
