Implementations§

Source §

impl HDRInput

Source

pub fn new(path: &Path) -> Result<Self, Error>

Create new HDRInput from a given file path. The file must have EXIF data for exposure and gain.

§Arguments

path: Path to file

returns: Result<HDRInput, Error>

§Errors

If image cannot be opened
If image doesn’t contain EXIF metadata for exposure and/or gain.

Source

pub fn with_exposure_and_gain( path: &Path, exposure: Duration, gain: f32, ) -> Result<Self, Error>

§Arguments

path:
exposure:
gain:

returns: Result<HDRInput, Error>

§Errors

If image cannot be opened
invalid gain
invalid exposure duration

Source

pub fn with_image( image: &DynamicImage, exposure: Duration, gain: f32, ) -> Result<Self, Error>

§Arguments

image:
exposure:
gain:

returns: Result<HDRInput, Error>

§Errors

invalid gain
invalid exposure duration

Source

pub fn get_exposure(&self) -> f32

Get exposure of the input item

Source

pub fn get_gain(&self) -> f32

Get gain of the input item

Source

pub fn get_buffer(&self) -> &Array3<f32>

Get underlying image data for the input item

Source

pub fn get_buffer_mut(&mut self) -> &mut Array3<f32>

Get underlying image data for the input item
