Struct ImageOptions 

pub struct ImageOptions {
    pub image_size: f64,
    pub hide_background_dots: bool,
    pub margin: u32,
    pub cross_origin: Option<String>,
    pub save_as_blob: bool,
}

Options for embedding an image/logo in the QR code.

Fields

image_size: f64

Size of the image relative to the QR code (0.0 to 1.0).

hide_background_dots: bool

Whether to hide dots behind the image.

margin: u32

Margin around the image in modules.

cross_origin: Option<String>

Cross-origin setting for loading images (browser context).

save_as_blob: bool

Whether to save the image as a data URL in SVG.

Implementations

impl ImageOptions

pub fn new() -> Self

Create new image options.

pub fn with_image_size(self, size: f64) -> Self

Set the image size ratio.

pub fn with_hide_background_dots(self, hide: bool) -> Self

Set whether to hide background dots.

pub fn with_margin(self, margin: u32) -> Self

Set the margin around the image.

pub fn with_cross_origin(self, cross_origin: impl Into<String>) -> Self

Set cross-origin setting.

pub fn with_save_as_blob(self, save: bool) -> Self

Set whether to save as blob/data URL.

Trait Implementations

impl Clone for ImageOptions

fn clone(&self) -> ImageOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ImageOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ImageOptions

fn eq(&self, other: &ImageOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
