Struct image::hdr::HDRDecoder

pub struct HDRDecoder<R> { /* fields omitted */ }

An Radiance HDR decoder

Methods

impl<R: BufRead> HDRDecoder<R>

pub fn new(reader: R) -> ImageResult<HDRDecoder<R>>

Reads Radiance HDR image header from stream r if the header is valid, creates HDRDecoder strict mode is enabled

pub fn with_strictness(reader: R, strict: bool) -> ImageResult<HDRDecoder<R>>

Reads Radiance HDR image header from stream reader, if the header is valid, creates HDRDecoder.

strict enables strict mode

Warning! Reading wrong file in non-strict mode could consume file size worth of memory in the process.

pub fn metadata(&self) -> HDRMetadata

Returns file metadata. Refer to HDRMetadata for details.

pub fn read_image_native(self) -> ImageResult<Vec<RGBE8Pixel>>

Consumes decoder and returns a vector of RGBE8 pixels

pub fn read_image_transform<T: Send, F: Send + Sync + Fn(RGBE8Pixel) -> T>(
    self,
    f: F
) -> ImageResult<Vec<T>>

Consumes decoder and returns a vector of tranformed pixels

pub fn read_image_ldr(self) -> ImageResult<Vec<Rgb<u8>>>

Consumes decoder and returns a vector of Rgb pixels. scale = 1, gamma = 2.2

pub fn read_image_hdr(self) -> ImageResult<Vec<Rgb<f32>>>

Consumes decoder and returns a vector of Rgb pixels.
