VintaSoft Annotation .NET Plug-in contains a set of classes, which allow to annotate images in very simple manner.

The classes are divided into several groups.

The classes, which store annotation data:

• AnnotationData and derived classes - store information about annotation data.
• AnnotationDataCollection - represents a collection of AnnotationData objects.

The classes intended for loading and saving annotations:

• AnnotationVintasoftBinaryFormatter - allows to save a collection of annotation data into packet of "Vintasoft binary" format; the packet can be saved either into separate file or into TIFF, PNG, JPEG, PDF file. Also this class allows to load a collection of annotation data from packet of "Vintasoft binary" format; the packet can be loaded either from separate file or from TIFF, PNG, JPEG, PDF file.
• AnnotationVintasoftXmpFormatter - allows to save a collection of annotation data into packet of "Vintasoft XMP" format; the packet can be saved either into separate file or into TIFF, JPEG, PDF file. Also this class allows to load a collection of annotation data from packet of "Vintasoft XMP" format; the packet can be loaded either from separate file or from TIFF, JPEG, PDF file.
• AnnotationWangFormatter - allows to save a collection of annotation data into WANG packet; the packet can be saved either into separate file or into TIFF file. Also this class allows to load a collection of annotation data from WANG packet; the packet can be loaded either from separate file or from TIFF file.

The classes, which define the appearance of annotation:

• AnnotationView and derived classes - determine how to display an annotation and how user can interact with annotation.
• AnnotationViewCollection - represents a collection of AnnotationView objects.

The classes, which store information about relations between the image, the annotation data and annotation appearance:

• AnnotationDataController - stores one-to-one links between the image (VintasoftImage) from the image collection (ImageCollection) and the annotation data collection (AnnotationDataCollection).
• AnnotationViewController - stores one-to-one links between the annotation data collection (AnnotationDataCollection) from the annotation data controller (AnnotationDataController) and the annotation view collection (AnnotationViewCollection).

The classes intended for displaying of annotations:

• AnnotationVisualTool - displays annotations and allows user interact with annotations.

The classes intended for displaying of images with annotations:

• AnnotationViewer - displays image collection with annotations.
• AnnotatedThumbnailViewer - displays thumbnail collection with annotations.

The classes intended to build rectangle based annotations: RectangularAnnotationBuilder.
The classes intended to build point based annotations: PointBasedAnnotationPointBuilder, PointBasedAnnotationLineBuilder.

The classes intended to transform rectangle based annotations: RectangularAnnotationTransformer, RectangularTextAnnotationTransformer.
The classes intended to transform point based annotations: PointBasedAnnotationRectangularTransformer, PointBasedAnnotationPointTransformer.
