将一个图像的调色板复制到另一个图像

使用不同的颜色空间和统计方法从源图像复制调色板到目标图像。

示例

let source = ImageReader::open("./assets/dwl.jpeg")
        .unwrap()
        .decode()
        .unwrap();
let source_dimensions = source.dimensions();
let destination = ImageReader::open("./assets/twl.jpeg")
    .unwrap()
    .decode()
    .unwrap();
let destination = destination.to_rgb8();
let destination_dimension = destination.dimensions();
let src = source.as_bytes();
let target = destination.as_bytes();
let mut dst = Vec::from(target);
copy_palette_rgb(
    src,
    source_dimensions.0,
    source_dimensions.1,
    & mut dst,
    destination_dimension.0,
    destination_dimension.1,
    1.,
    TransferColorspace::OKLAB,
)
.unwrap();

image::save_buffer(
    "converted_oklab.jpg",
    & dst,
    destination_dimension.0,
    destination_dimension.1,
    image::ExtendedColorType::Rgb8,
)
.unwrap();
