The shaders that can be chosen for the renderer

Variants

Simple

Flat colour shader The erase texture (which should be a MSAA texture) is subtracted from anything drawn, if present

Fields

erase_texture: Option<TextureId>

clip_texture: Option<TextureId>

DashedLine

Flat colour with ‘dashed line’ texturing using a 1D texture

Fields

dash_texture: TextureId

erase_texture: Option<TextureId>

clip_texture: Option<TextureId>

Texture

Colour derived from a texture with a transform mapping from canvas coordinates to texture coordinates

Fields

texture: TextureId

texture_transform: Matrix

repeat: bool

alpha: f32

erase_texture: Option<TextureId>

clip_texture: Option<TextureId>

LinearGradient

Colour dervide from a 1D texture using a transform mapping (used for rendering linear gradients)

Fields

texture: TextureId

texture_transform: Matrix

repeat: bool

alpha: f32

erase_texture: Option<TextureId>

clip_texture: Option<TextureId>

Implementations

impl ShaderType

pub fn with_erase_mask( self, new_erase_mask_texture: Option<TextureId>, ) -> ShaderType

Adds an erase mask texture to the existing shader

pub fn with_clip_mask( self, new_clip_mask_texture: Option<TextureId>, ) -> ShaderType

Adds a clip mask texture to the existing shader

Trait Implementations

impl Clone for ShaderType

fn clone(&self) -> ShaderType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShaderType

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

Formats the value using the given formatter.

impl PartialEq for ShaderType

fn eq(&self, other: &ShaderType) -> 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.
