[RUST/IMAGE] crop 함수 : 이미지 잘라내기

■ crop 함수를 사용해 이미지를 잘라내는 방법을 보여준다.

▶ 예제 코드 (RS)


use image;
use image::imageops;

let mut source_dynamic_image : image::DynamicImage = image::open("d:/source.jpg").unwrap();

let subsidary_image : image::SubImage<&mut image::DynamicImage> = imageops::crop
(
    &mut source_dynamic_image,
    50,
    50,
    200,
    200
);

let target_image_buffer : image::ImageBuffer<image::Rgba<u8>, Vec<u8>> = subsidary_image.to_image();

target_image_buffer.save("d:/target.jpg").unwrap();

use image;

use image::imageops;

let mut source_dynamic_image : image::DynamicImage = image::open("d:/source.jpg").unwrap();

let subsidary_image : image::SubImage<&mut image::DynamicImage> = imageops::crop

(

&mut source_dynamic_image,

50,

200,

200

);

let target_image_buffer : image::ImageBuffer<image::Rgba<u8>, Vec<u8>> = subsidary_image.to_image();

target_image_buffer.save("d:/target.jpg").unwrap();
