View thumbnails with annotations in WPF
In This Topic
WpfAnnotatedThumbnailViewer class is derived from
WpfThumbnailViewer class and intended for viewing image thumbnails with annotations.
WpfAnnotatedThumbnailViewer class extends the functionality of
WpfThumbnailViewer class and allows to:
Here is C#/VB.NET code showing how to load images with annotations from file and display their thumbnails with annotations:
void LoadImagesWithAnnotation(
Vintasoft.Imaging.Annotation.Wpf.UI.WpfAnnotatedThumbnailViewer wpfAnnotatedThumbnailViewer, string filename)
{
wpfAnnotatedThumbnailViewer.Images.Add(filename);
}
Private Sub LoadImagesWithAnnotation(wpfAnnotatedThumbnailViewer As Vintasoft.Imaging.Annotation.Wpf.UI.WpfAnnotatedThumbnailViewer, filename As String)
wpfAnnotatedThumbnailViewer.Images.Add(filename)
End Sub
WpfAnnotatedThumbnailViewer class can be used separately or together with
AnnotationViewer class.
If
WpfAnnotatedThumbnailViewer class is used separately then it just shows annotations on thumbnails.
If
WpfAnnotatedThumbnailViewer class is used together with
AnnotationViewer class then it shows annotations on thumbnails and, at the same time, performs simultaneous update of active image thumbnail in
AnnotationViewer when annotations associated with the thumbnail are changing (new annotation is added, existing annotation is transformed, etc).
