[RUST/IMAGE] resize 함수 : 이미지 크기 변경하기

■ resize 함수를 사용해 이미지 크기를 변경하는 방법을 보여준다.

▶ 예제 코드 (RS)


use image;
use image::imageops;

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

let target_image_buffer : image::ImageBuffer<image::Rgba<u8>, Vec<u8>> = imageops::resize
(
    &mut source_dynamic_image,
    256,
    256,
    imageops::Lanczos3
);

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 target_image_buffer : image::ImageBuffer<image::Rgba<u8>, Vec<u8>> = imageops::resize

(

&mut source_dynamic_image,

256,

imageops::Lanczos3

);

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