Link between annotation data and view collections in WinForms

In This Topic

The AnnotationViewController class stores one-to-one links between one AnnotationDataCollection from the AnnotationDataController and one AnnotationViewCollection.

AnnotationViewController class allows to:

access collections of annotations
get collection of annotation's external views for the image using AnnotationViewController.GetAnnotationsView method
burn annotations on images using AnnotationViewController.BurnAnnotationCollectionOnImages method
get cloned image with burned annotations using AnnotationViewController.GetImageWithAnnotations method

Here is C#/VB.NET code that shows how to load an image collection, add annotation to the first image, burn annotation on the image and save the image collection to a new file:

// Create the image collection and add images to collection.
Vintasoft.Imaging.ImageCollection imageCollection = 
    new Vintasoft.Imaging.ImageCollection();
imageCollection.Add(@"D:\Images\AutoContrast.jpg");
imageCollection.Add(@"D:\Images\AutoColors.jpg");

// Create annotation controllers associated with image collection.
Vintasoft.Imaging.Annotation.AnnotationDataController annotationDataController = 
    new Vintasoft.Imaging.Annotation.AnnotationDataController(imageCollection);
Vintasoft.Imaging.Annotation.UI.AnnotationViewController annotationViewController = 
    new Vintasoft.Imaging.Annotation.UI.AnnotationViewController(annotationDataController);

// Create a data of rectangle annotation.
Vintasoft.Imaging.Annotation.RectangleAnnotationData rectangleAnnotationData = 
    new Vintasoft.Imaging.Annotation.RectangleAnnotationData();
rectangleAnnotationData.Location = new System.Drawing.PointF(340, 150);
rectangleAnnotationData.Size = new System.Drawing.SizeF(220, 150);
// Create a view of rectangle annotation.
Vintasoft.Imaging.Annotation.UI.RectangleAnnotationView rectangleAnnotationView = 
    new Vintasoft.Imaging.Annotation.UI.RectangleAnnotationView(rectangleAnnotationData);
// Add the rectangle annotation to the annotation controller.
annotationViewController[0].Add(rectangleAnnotationView);

// Burn annotation collection on the first image.
annotationViewController.BurnAnnotationCollectionOnImage(0);

// Save image collection to TIFF file.
imageCollection.SaveSync(@"D:\ImageCollection.tif", true);

VB.NET

' Create the image collection and add images to collection.
Dim imageCollection As New Vintasoft.Imaging.ImageCollection()
imageCollection.Add("D:\Images\AutoContrast.jpg")
imageCollection.Add("D:\Images\AutoColors.jpg")

' Create annotation controllers associated with image collection.
Dim annotationDataController As New Vintasoft.Imaging.Annotation.AnnotationDataController(imageCollection)
Dim annotationViewController As New Vintasoft.Imaging.Annotation.UI.AnnotationViewController(annotationDataController)

' Create a data of rectangle annotation.
Dim rectangleAnnotationData As New Vintasoft.Imaging.Annotation.RectangleAnnotationData()
rectangleAnnotationData.Location = New System.Drawing.PointF(340, 150)
rectangleAnnotationData.Size = New System.Drawing.SizeF(220, 150)
' Create a view of rectangle annotation.
Dim rectangleAnnotationView As New Vintasoft.Imaging.Annotation.UI.RectangleAnnotationView(rectangleAnnotationData)
' Add the rectangle annotation to the annotation controller.
annotationViewController(0).Add(rectangleAnnotationView)

' Burn annotation collection on the first image.
annotationViewController.BurnAnnotationCollectionOnImage(0)

' Save image collection to TIFF file.
imageCollection.SaveSync("D:\ImageCollection.tif", True)

Access to collections of annotations

The AnnotationViewController.Images property allows to get an image collection, which is managed by annotation controller. The collections of annotation data can be accessed using AnnotationViewController.DataController property. The collections of annotation's visual appearances can be accessed via indexer.
