Expand description

Adapter to conform to ImageDecoder trait

Implementations§

source§

impl<R: BufRead> HdrAdapter<R>

source

pub fn new(r: R) -> ImageResult<HdrAdapter<R>>

Creates adapter

source

pub fn new_nonstrict(r: R) -> ImageResult<HdrAdapter<R>>

Allows reading old Radiance HDR images

Trait Implementations§

source§

impl<R: Debug + Read> Debug for HdrAdapter<R>

source§

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

Formats the value using the given formatter. Read more
source§

impl<'a, R: 'a + BufRead> ImageDecoder<'a> for HdrAdapter<R>

source§

type Reader = HdrReader<R>

The type of reader produced by into_reader.
source§

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

Returns a tuple containing the width and height of the image
source§

fn color_type(&self) -> ColorType

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

fn into_reader(self) -> ImageResult<Self::Reader>

👎Deprecated: Planned for removal. See https://github.com/image-rs/image/issues/1989
Returns a reader that can be used to obtain the bytes of the image. For the best performance, always try to read at least scanline_bytes from the reader at a time. Reading fewer bytes will cause the reader to perform internal buffering.
source§

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

Returns all the bytes in the image. Read more
source§

fn original_color_type(&self) -> ExtendedColorType

Returns the color type of the image file before decoding
source§

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

Returns the ICC color profile embedded in the image Read more
source§

fn total_bytes(&self) -> u64

Returns the total number of bytes in the decoded image. Read more
source§

fn scanline_bytes(&self) -> u64

👎Deprecated: Planned for removal. See https://github.com/image-rs/image/issues/1989
Returns the minimum number of bytes that can be efficiently read from this decoder. This may be as few as 1 or as many as total_bytes().
source§

fn read_image_with_progress<F: Fn(Progress)>( self, buf: &mut [u8], progress_callback: F, ) -> ImageResult<()>

👎Deprecated: Use read_image instead. See https://github.com/image-rs/image/issues/1989
Same as read_image but periodically calls the provided callback to give updates on loading progress.
source§

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

Set decoding limits for this decoder. See Limits for the different kinds of limits that is possible to set. Read more
source§

impl<'a, R: 'a + BufRead + Seek> ImageDecoderRect<'a> for HdrAdapter<R>

source§

fn read_rect_with_progress<F: Fn(Progress)>( &mut self, x: u32, y: u32, width: u32, height: u32, buf: &mut [u8], progress_callback: F, ) -> ImageResult<()>

👎Deprecated: Use read_image instead. See https://github.com/image-rs/image/issues/1989
Decode a rectangular section of the image, periodically reporting progress. Read more
source§

fn read_rect( &mut self, x: u32, y: u32, width: u32, height: u32, buf: &mut [u8], ) -> ImageResult<()>

Decode a rectangular section of the image; see read_rect_with_progress().
