Struct CanvasExports 

pub struct CanvasExports {
    pub bitmap: bool,
    pub pdf: bool,
    /* private fields */
}

What this toolkit can export a canvas drawing to (Cap::CanvasBitmap, Cap::CanvasPdf). Read it to enable or hide export commands, the way image_encode_formats decides which formats to offer.

Fields

bitmap: bool

render_bitmap works here, and with it PNG export wherever Bitmap::encode writes PNG (see CanvasExports::png).

pdf: bool

render_pdf works here: the platform has a native PDF writer.

Implementations

impl CanvasExports

pub fn png(&self) -> bool

Whether a drawing can become PNG bytes here: a rendered bitmap plus a PNG encoder.
