Struct image::codecs::hdr::HdrDecoder

pub struct HdrDecoder<R> { /* private fields */ }

An Radiance HDR decoder

Implementations

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, output_slice: &mut [T] ) -> ImageResult<()>

Consumes decoder and returns a vector of transformed pixels

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

Consumes decoder and returns a vector of Rgb<u8> pixels. scale = 1, gamma = 2.2

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

Consumes decoder and returns a vector of Rgb<f32> pixels.
