Struct ImageRequest 

#[non_exhaustive]
pub struct ImageRequest {
    pub drawing: usize,
    pub file: Option<DroppedFileHandle>,
}

An image drawing waiting for its picture, from ChartEvent::ImageRequested.

The chart reads no file and opens no dialog. For a placed image, file is None and the host may offer a file chooser; for a dropped file it holds egui’s handle, which gives the path on native platforms and the bytes on the web. Treat the file as untrusted: check its size, format and pixel dimensions before loading it, then call Chart::set_drawing_image with an address the host’s image loaders resolve.

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.

drawing: usize

Id of the image drawing to answer.

file: Option<DroppedFileHandle>

The dropped file, or None when the user placed the image with the tool.
