TrayIconImageDelegate.fromBytes constructor

TrayIconImageDelegate.fromBytes(ByteBuffer pixels)

A TrayIconImageDelegate that uses an RGBA image buffer.

The buffer is expected to be in the format of an RGBA image where the size equals TrayIcon.preferredImageSize.

Implementation

TrayIconImageDelegate.fromBytes(ByteBuffer pixels) {
  final size = TrayIcon.preferredImageSize;
  int x = size.width.toInt();
  int y = size.height.toInt();
  if (pixels.lengthInBytes != x * y * 4) {
    throw ArgumentError(
        "The buffer must have $x×$y pixels and 4 bytes per pixel.");
  }
  setIcon = (id, plugin) =>
      plugin.setImageFromPixels(id, x, y, pixels.asInt32List());
}
