Struct nannou::image::hdr::HdrDecoder

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

An Radiance HDR decoder

Implementations

impl<R> HdrDecoder<R> where
    R: BufRead, 

pub fn new(reader: R) -> Result<HdrDecoder<R>, ImageError>

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
) -> Result<HdrDecoder<R>, ImageError>

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) -> Result<Vec<Rgbe8Pixel>, ImageError>

Consumes decoder and returns a vector of RGBE8 pixels

pub fn read_image_transform<T, F>(
    self,
    f: F,
    output_slice: &mut [T]
) -> Result<(), ImageError> where
    F: Send + Sync + Fn(Rgbe8Pixel) -> T,
    T: Send, 

Consumes decoder and returns a vector of transformed pixels

pub fn read_image_ldr(self) -> Result<Vec<Rgb<u8>>, ImageError>

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

pub fn read_image_hdr(self) -> Result<Vec<Rgb<f32>>, ImageError>

Consumes decoder and returns a vector of Rgb pixels.

Trait Implementations

impl<R> Debug for HdrDecoder<R> where
    R: Debug, 

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

Formats the value using the given formatter.

impl<R> IntoIterator for HdrDecoder<R> where
    R: BufRead, 

type Item = Result<Rgbe8Pixel, ImageError>

The type of the elements being iterated over.

type IntoIter = HdrImageDecoderIterator<R>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <HdrDecoder<R> as IntoIterator>::IntoIter

Creates an iterator from a value.
