Struct ImageSource 

pub struct ImageSource<'a> { /* private fields */ }

View of an image, for use with OcrEngine::prepare_input.

Implementations

impl<'a> ImageSource<'a>

pub fn from_bytes( bytes: &'a [u8], dimensions: (u32, u32), ) -> Result<ImageSource<'a>, ImageSourceError>

Create an image source from a buffer of pixels in HWC order.

An image loaded using the image crate can be converted to an ImageSource using:

use ocrs::ImageSource;

let image = image::open("image.jpg")?.into_rgb8();
let img_source = ImageSource::from_bytes(image.as_raw(), image.dimensions())?;

pub fn from_tensor<T>( data: NdTensorView<'a, T, 3>, order: DimOrder, ) -> Result<ImageSource<'a>, ImageSourceError>

where NdTensorView<'a, T, 3>: Into<ImagePixels<'a>>,

Create an image source from a tensor of bytes (u8) or floats (f32), in either channels-first (CHW) or channels-last (HWC) order.
