Struct HdrDecoder 

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

An Radiance HDR decoder

Implementations

impl<R> HdrDecoder<R>

where R: Read,

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 new_nonstrict(reader: R) -> Result<HdrDecoder<R>, ImageError>

Allows reading old Radiance HDR images

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.

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> ImageDecoder for HdrDecoder<R>

where R: Read,

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

Returns a tuple containing the width and height of the image

fn color_type(&self) -> ColorType

Returns the color type of the image data produced by this decoder

fn read_image(self, buf: &mut [u8]) -> Result<(), ImageError>

Returns all the bytes in the image.

fn read_image_boxed( self: Box<HdrDecoder<R>>, buf: &mut [u8], ) -> Result<(), ImageError>

Use read_image instead; this method is an implementation detail needed so the trait can be object safe.

fn original_color_type(&self) -> ExtendedColorType

Returns the color type of the image file before decoding

fn icc_profile(&mut self) -> Result<Option<Vec<u8>>, ImageError>

Returns the ICC color profile embedded in the image, or Ok(None) if the image does not have one.

fn exif_metadata(&mut self) -> Result<Option<Vec<u8>>, ImageError>

Returns the raw Exif chunk, if it is present. A third-party crate such as kamadak-exif is required to actually parse it.

fn orientation(&mut self) -> Result<Orientation, ImageError>

Returns the orientation of the image.

fn total_bytes(&self) -> u64

Returns the total number of bytes in the decoded image.

fn set_limits(&mut self, limits: Limits) -> Result<(), ImageError>

Set the decoder to have the specified limits. See Limits for the different kinds of limits that is possible to set.
