Implementations

impl<'a, 'c> Image<'a, 'c>

pub fn empty() -> Self

An Image with no renderable content. Useful for starting a template for creating several similar images using a builder pattern.

pub fn from_path(filename: &'a str) -> Self

Create an SVG Image, read from filename, which is colored to match Style.icon_fg

pub fn untinted(filename: &'a str) -> Self

Create an SVG Image, read from filename.

The image’s intrinsic colors will be used, it will not be tinted like Image::icon, unless you also call color()

pub fn from_bytes(labeled_bytes: (&'a str, &'a [u8])) -> Self

Create a new SVG Image from bytes.

• labeled_bytes: is a (label, bytes) tuple you can generate with include_labeled_bytes!
• label: a label to describe the bytes for debugging purposes
• bytes: UTF-8 encoded bytes of the SVG

pub fn from_batch(batch: GeomBatch, bounds: Bounds) -> Self

Create a new Image from a GeomBatch.

pub fn source(self, source: ImageSource<'a>) -> Self

Set a new source for the Image’s data.

This will replace any previously set source.

pub fn source_path(self, path: &'a str) -> Self

Set the path to an SVG file for the image.

This will replace any image source previously set.

pub fn source_bytes(self, labeled_bytes: (&'a str, &'a [u8])) -> Self

Set the bytes for the image.

This will replace any image source previously set.

• labeled_bytes: is a (label, bytes) tuple you can generate with include_labeled_bytes!
• label: a label to describe the bytes for debugging purposes
• bytes: UTF-8 encoded bytes of the SVG

pub fn source_batch(self, batch: GeomBatch, bounds: Bounds) -> Self

Set the GeomBatch for the button.

This will replace any image source previously set.

This method is useful when doing more complex transforms. For example, to re-write more than one color for your image, do so externally and pass in the resultant GeomBatch here.

pub fn tooltip(self, tooltip: impl Into<Text>) -> Self

Add a tooltip to appear when hovering over the image.

pub fn merged_image_style(&'c self, other: &'c Self) -> Self

Create a new Image based on self, but overriding with any values set on other.

pub fn color<RWC: Into<RewriteColor>>(self, value: RWC) -> Self

Rewrite the color of the image.

pub fn bg_color(self, value: Color) -> Self

Set a background color for the image.

pub fn dims<D: Into<ScreenDims>>(self, dims: D) -> Self

Scale the bounds containing the image. If image_dims are not specified, the images intrinsic size will be used.

See Self::content_mode to control how the image scales to fit its custom bounds.

pub fn content_mode(self, value: ContentMode) -> Self

If a custom dims was set, control how the image should be scaled to its new bounds

If dims were not specified, the image will not be scaled, so content_mode has no affect.

The default, ContentMode::ScaleAspectFit will only grow as much as it can while maintaining its aspect ratio and not exceeding its bounds

pub fn corner_rounding<R: Into<CornerRounding>>(self, value: R) -> Self

Set independent rounding for each of the image’s corners

pub fn padding<EI: Into<EdgeInsets>>(self, value: EI) -> Self

Set padding for the image

pub fn build_batch(&self, ctx: &EventCtx<'_>) -> Option<(GeomBatch, Bounds)>

Render the Image and any styling (padding, background, etc.) to a GeomBatch.

pub fn into_widget(self, ctx: &EventCtx<'_>) -> Widget

Trait Implementations

impl<'a, 'c> Clone for Image<'a, 'c>

fn clone(&self) -> Image<'a, 'c>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, 'c> Debug for Image<'a, 'c>

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

Formats the value using the given formatter.

impl<'a, 'c> Default for Image<'a, 'c>

fn default() -> Image<'a, 'c>

Returns the “default value” for a type.
