Struct image_go_nord::Options

pub struct Options {
    pub resize: u32,
    pub quantize: i32,
    pub blur: f32,
}

These options modify the algorithm(s) used by convert. You can specify built-in pre-processing operations like resizing and quantization, processing parameters like transparency tolerance and average kernel, and post-processing operations like Gaussian blur.

Options implements std::default::Default, so you can use struct builder syntax to easily make an Options struct that “overrides” the default struct.

let options = Options {
    resize: [1920, 1080],
    blur: 0.4,
    ..Default::default()
};
assert_eq!(options, Options {
    resize: [1920, 1080],
    quantize: 0,
    avg: [0, 0],
    transparency_tolerance: 0,
    blur: 0.4,
})

Fields

resize: u32

👎 Deprecated

Resize image by a certain factor before performing other processing. The image will be resized using linear filtering back to the original dimensions before it is output. This will cause the algorithm to consider bigger “pixels” in the image, which will result in a lower quality conversion.

quantize: i32

Quantize the image by the given balance. The value must be between 1 and 30. A value closer to 1 will be slower, but provide better quantization. The default value of 10 is a good balance between speed and quality.

Passing any invalid value (like 0) disables quantization, which is the default behavior

blur: f32

Perform a Gaussian blur on the output image. This can help smooth gradients and remove unwanted artifacts.

0.0 means don’t blur.
