no image to copy

Error message

no image to copy

What it means

The Copy command logs the CopyImageButton event and then attempts to put the current image on the clipboard; this error is the sentinel failure when there is no image data to copy. It fires when the acetate layer has no ink (so no InkedImage can be snapshotted) and no CapturedImage exists either — the user invoked Copy before capturing or annotating anything.

Solutions

1. Check MainWindow.acetateLayer.HasInk() and ViewModel.CapturedImage before invoking the copy logic and show a friendly message when both are empty
2. Disable the Copy button in the ActionRibbon until an image is available
3. Ensure PictureConverter.GenerateSnapshot produced a non-null image before calling ClipboardManager.Copy
