Struct Renderer 

pub struct Renderer { /* private fields */ }

The software renderer allows rendering layouts entirely on the CPU. This is surprisingly fast and can be considered the default renderer. There are two versions of the software renderer. This version of the software renderer owns the image it renders into.

Implementations

impl Renderer

pub fn new() -> Self

Creates a new software renderer.

pub fn render( &mut self, state: &LayoutState, [width, height]: [u32; 2], ) -> Option<(f32, f32)>

Renders the layout state provided with the chosen resolution. It may detect that the layout got resized. In that case it returns the new ideal size. This is just a hint and can be ignored entirely. The image is always rendered with the resolution provided.

pub fn image_data(&self) -> &[u8]

Accesses the image as a byte slice of RGBA8 encoded pixels (red, green, blue, alpha with each channel being an u8).

pub fn into_image_data(self) -> Vec<u8>

Turns the whole renderer into the underlying image buffer of RGBA8 encoded pixels (red, green, blue, alpha with each channel being an u8).

pub fn image(&self) -> ImageBuffer<Rgba<u8>, &[u8]>

Accesses the image.

pub fn into_image(self) -> RgbaImage

Turns the whole renderer into the underlying image.

Trait Implementations

impl Default for Renderer

fn default() -> Self

Returns the “default value” for a type.
