[−][src]Struct image::hdr::HDRDecoder
An Radiance HDR decoder
Methods
impl<R: BufRead> HDRDecoder<R>[src]
pub fn new(reader: R) -> ImageResult<HDRDecoder<R>>[src]
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>>[src]
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[src]
Returns file metadata. Refer to HDRMetadata for details.
pub fn read_image_native(self) -> ImageResult<Vec<RGBE8Pixel>>[src]
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
) -> ImageResult<Vec<T>>[src]
self,
f: F
) -> ImageResult<Vec<T>>
For trivial types T this interface is less safe and less efficient than one takingan output slice. Semantics may be confusing for non-trivial types. Consider upgrading to v0.22.
Consumes decoder and returns a vector of transformed pixels.
Note: This method should not be called with a parameter T that has a Drop impl. In case of
error or panic, it will never call this Drop implementation even for pixels that have
already been successfully decoded.
pub fn read_image_ldr(self) -> ImageResult<Vec<Rgb<u8>>>[src]
Consumes decoder and returns a vector of Rgb
pub fn read_image_hdr(self) -> ImageResult<Vec<Rgb<f32>>>[src]
Consumes decoder and returns a vector of Rgb
