Struct TextRenderer

pub struct TextRenderer { /* private fields */ }

Instance Buffer Setup for Text.

Implementations

impl TextRenderer

pub fn new(renderer: &GpuRenderer) -> Result<Self, GraphicsError>

Creates a new TextRenderer.

pub fn add_buffer_store( &mut self, renderer: &GpuRenderer, index: OrderedIndex, buffer_layer: usize, )

Adds a Buffer OrderedIndex to the Rendering Store to get processed. This must be done before TextRenderer::finalize but after Text::update in order for it to Render.

Arguments

• index: The OrderedIndex of the Object we want to render.
• buffer_layer: The Buffer Layer we want to add this Object too.

pub fn finalize(&mut self, renderer: &mut GpuRenderer)

Finalizes the Buffer by processing staged OrderedIndex’s and uploading it to the GPU. Must be called after all the TextRenderer::add_buffer_store’s.

pub fn text_update( &mut self, text: &mut Text, atlas: &mut TextAtlas, renderer: &mut GpuRenderer, buffer_layer: usize, ) -> Result<(), GraphicsError>

Updates a Text and adds its [TextOrderedIndex] to staging using TextRenderer::add_buffer_store. This must be done before TextRenderer::finalize in order for it to Render.

Arguments

• text: Text we want to update and prepare for rendering.
• atlas: TextAtlas the Text needs to render with.
• buffer_layer: The Buffer Layer we want to add this Object too.

pub fn use_clipping(&mut self)

Text does not use Scissor Clipping. It uses its own Internal Bounds Clipper.
