toImage method

Future<ByteData?> toImage({
  1. int width = 512,
  2. int height = 256,
  3. Color? color,
  4. Color? background,
  5. double? strokeWidth,
  6. double? maxStrokeWidth,
  7. HandSignatureDrawer? drawer,
  8. double border = 0.0,
  9. ImageByteFormat format = ImageByteFormat.png,
  10. bool fit = false,
})

Exports data to raw image.

If fit is enabled, the path will be normalized and scaled to fit given width and height.
