Struct Resources 

pub struct Resources {
    pub(crate) image_registry: ImageRegistry,
    pub(crate) glyph_prep_cache: GlyphPrepCache,
    pub(crate) glyph_resources: Option<GlyphAtlasResources>,
}

Persistent resources required by Vello CPU for rendering.

You should create one such instance per renderer.

Fields

image_registry: ImageRegistry

glyph_prep_cache: GlyphPrepCache

glyph_resources: Option<GlyphAtlasResources>

Implementations

impl Resources

pub fn new() -> Self

Create a new set of renderer resources.

pub(crate) fn before_render(&mut self, render_mode: RenderMode)

pub(crate) fn after_render(&mut self)

impl Resources

Image registry implementation.

pub fn register_image(&mut self, pixmap: Arc<Pixmap>) -> ImageId

Register a pixmap in the image registry and return its ImageId.

pub fn destroy_image(&mut self, id: ImageId) -> bool
