Annotation style editor for Xamarin.Android viewer

AnnotStyleDialogFragment is a DialogFragment that shows annotation style properties in a bottom sheet view. With this style dialog, users can change the annotation color with the advanced color picker or directly select preset styles. The style dialog also provides a recent and a favorite list for quick access.

The AnnotationStyleDialogFragment.Builder class allows you to create an AnnotStyleDialogFragment with a specified AnnotStyle. The AnnotStyle represents the initial annotation style to display.

Example

// 1. Instantiate an AnnotStyle with its constructor
var annotStyle = new pdftron.PDF.Model.AnnotStyle();
// 2. Set annotation type to annot style
annotStyle.AnnotType = (int)Annot.Type.e_Square;
// 3. Set blue stroke, yellow fill color, thickness 5, opacity 0.8 to the annotation style.
annotStyle.SetStyle(Android.Graphics.Color.Blue, Android.Graphics.Color.Yellow, 5, 0.8f);
// 4. Instantiate an AnnotStyleDialogFragment.Builder with its constructor
var styleDialogBuilder = new AnnotStyleDialogFragment.Builder(annotStyle);
// 5. Set anchor rectangle if you want the `AnnotStyleDialogFragment` be displayed as a popup window in tablet mode
styleDialogBuilder.SetAnchor(new Android.Graphics.Rect(0, 0, 100, 1000));
// 6. Build AnnotStyleDialogFragment with the arguments supplied to this builder.
var annotStyleDialog = styleDialogBuilder.Build();

Afterwards, to show an annotation style dialog call Show(FragmentManager). Similarly, to dismiss the annotation style dialog programmatically call Dismiss().

You can listen to annotation style changes by setting an OnAnnotStyleChangeListener to your AnnotStyleDialogFragment using SetOnAnnotStyleChangeListener. The AnnotStyleDialogFragment raises an event when a style change occurs (such as a color change, thickness change, text color change, etc., allowing you to define custom behavior for such events.
