Struct HdrDecoder

pub struct HdrDecoder<R> {
    r: R,
    width: u32,
    height: u32,
    meta: HdrMetadata,
}

An Radiance HDR decoder

Fields

r: R

width: u32

height: u32

meta: HdrMetadata

Implementations

impl<R: Read> HdrDecoder<R>

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

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) -> ImageResult<Self>

Allows reading old Radiance HDR images

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.

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

Trait Implementations

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

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

Formats the value using the given formatter.

impl<R: Read> ImageDecoder for HdrDecoder<R>

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]) -> ImageResult<()>

Returns all the bytes in the image.

fn read_image_boxed(self: Box<Self>, buf: &mut [u8]) -> ImageResult<()>

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) -> ImageResult<Option<Vec<u8>>>

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

fn exif_metadata(&mut self) -> ImageResult<Option<Vec<u8>>>

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) -> ImageResult<Orientation>

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) -> ImageResult<()>

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