Struct ResizeOptions 

pub struct ResizeOptions {
    pub algorithm: ResizeAlg,
    pub cropping: SrcCropping,
    pub mul_div_alpha: bool,
}

Options for configuring a resize process.

Fields

algorithm: ResizeAlg

Default: ResizeAlg::Convolution(FilterType::Lanczos3)

cropping: SrcCropping

Default: SrcCropping::None.

mul_div_alpha: bool

Enable or disable consideration of the alpha channel when resizing.

Default: true.

Implementations

impl ResizeOptions

pub fn new() -> Self

pub fn resize_alg(&self, resize_alg: ResizeAlg) -> Self

Set resize algorythm.

pub fn crop(&self, left: f64, top: f64, width: f64, height: f64) -> Self

Set crop box for source image.

pub fn fit_into_destination(&self, centering: Option<(f64, f64)>) -> Self

Fit a source image into the aspect ratio of a destination image without distortions.

centering is used to control the cropping position. Use (0.5, 0.5) for center cropping (e.g. if cropping the width, take 50% off of the left side, and therefore 50% off the right side). (0.0, 0.0) will crop from the top left corner (i.e. if cropping the width, take all the crop off of the right side, and if cropping the height, take all of it off the bottom). (1.0, 0.0) will crop from the bottom left corner, etc. (i.e. if cropping the width, take all the crop off the left side, and if cropping the height, take none from the top, and therefore all off the bottom).

pub fn use_alpha(&self, v: bool) -> Self

Enable or disable consideration of the alpha channel when resizing.
