Struct ChartImage 

#[non_exhaustive]
pub struct ChartImage {
    pub size: [u32; 2],
    pub primitives: Vec<ClippedPrimitive>,
    pub textures_delta: TexturesDelta,
}

A complete offscreen frame for an egui renderer, at one pixel per point. Upload textures_delta.set, draw primitives over transparent black at size, then release the textures. The host owns GPU readback, PNG encoding and file/clipboard delivery. This uses its own texture namespace; render with a dedicated egui renderer. Hosts must also bind any user textures referenced by their image sources whose pixels were not supplied in ImageExportOptions::textures before drawing.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

size: [u32; 2]

Exact output dimensions in pixels.

primitives: Vec<ClippedPrimitive>

Tessellated chart, header, study panes and requested layout widgets.

textures_delta: TexturesDelta

Textures referenced by the primitives.
