Represents an action for a render target

Variants

SetTransform(Matrix)

Sets the transformation matrix to use for future renderings

CreateVertex2DBuffer(VertexBufferId, Vec<Vertex2D, Global>)

Creates a vertex buffer with the specified 2D vertices in it (replacing any existing buffer)

CreateIndexBuffer(IndexBufferId, Vec<u16, Global>)

Creates an index buffer with the specified 2D vertices in it (replacing any existing buffer)

FreeVertexBuffer(VertexBufferId)

Frees an existing vertex buffer

FreeIndexBuffer(IndexBufferId)

Frees an existing index buffer

BlendMode(BlendMode)

Sets the blend mode for future drawing operations (SourceOver is the default)

CreateRenderTarget(RenderTargetId, TextureId, usize, usize, RenderTargetType)

Creates a new render target of the specified size, as the specified texture

FreeRenderTarget(RenderTargetId)

Frees up an existing render target

SelectRenderTarget(RenderTargetId)

Send future rendering instructions to the specified render target

RenderToFrameBuffer

Send future rendering instructions to the main frame buffer

ShowFrameBuffer

Display the current frame buffer on-screen

DrawFrameBuffer(RenderTargetId, i32, i32)

Renders the specified framebuffer to the current framebuffer

CreateTextureBgra(TextureId, usize, usize)

Creates an 8-bit BGRA 2D texture of the specified size

CreateTextureMono(TextureId, usize, usize)

Creates an 8-bit monochrome 2D texture of the specified size

Create1DTextureBgra(TextureId, usize)

Creates a 1 dimensional 8-bit BGRA texture of the specified size

Create1DTextureMono(TextureId, usize)

Creates a 1 dimensional 8-bit monochrome texture of the specified size

WriteTextureData(TextureId, (usize, usize), (usize, usize), Arc<Vec<u8, Global>>)

Given a region in a 2D texture and a set of bytes to write, updates the texture with those bytes

WriteTexture1D(TextureId, usize, usize, Arc<Vec<u8, Global>>)

Given a region in a 1D texture and a set of bytes to write, updates the texture with those bytes

CreateMipMaps(TextureId)

Generates mip-maps for the specified texture ID

CopyTexture(TextureId, TextureId)

Copies a texture from a source ID to a target ID (replacing any existing texture at that ID)

Mipmap levels are not copied by this operation, so would need to be regenerated

FreeTexture(TextureId)

Frees up an existing texture

Clear(Rgba8)

Clears the current render target to the specified colour

UseShader(ShaderType)

Uses the specified shader

DrawTriangles(VertexBufferId, Range<usize>)

Renders triangles from a vertex buffer (with no texture)

Parameters are the range of vertices to use

DrawIndexedTriangles(VertexBufferId, IndexBufferId, usize)

Renders triangles using an index buffer

Trait Implementations

impl Clone for RenderAction

fn clone(&self) -> RenderAction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RenderAction

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

Formats the value using the given formatter.

impl PartialEq<RenderAction> for RenderAction

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl StructuralPartialEq for RenderAction
