Using Pictures in Annotation Objects

The AnnPicture class provides a picture object that is used by several LEADTOOLS annotation object classes. The following LEADTOOLS annotation objects use the AnnPicture class:

AnnImageObject

AnnHotspotObject

AnnFreehandHotspotObject

AnnPointObject

AnnStampObject

Each of these classes (either through the direct implementation or inheritance) access properties that control how the AnnPicture is used in the annotation object.

AnnImageObject:

The AnnImageObject class derives from AnnRectangleObject and adds the Picture property to fill the object's Bounds.

AnnHotspotObject:

The AnnHotspotObject class derives from AnnImageObject and adds the DefaultPicture property to set the default AnnPicture used to fill the object's Bounds.

AnnFreehandHotspotObject:

The AnnFreehandHotspotObject class derives from AnnPolylineObject and adds both the Picture and DefaultPicture properties.

AnnPointObject:

The AnnPointObject class derives from AnnObject and adds both the Picture and DefaultPicture properties.

AnnStampObject: The AnnStampObject class derives from AnnTextObject and adds the Picture property.
