Annotations are currently shown using a marker along the top of a core. The marker is a simple interactive visual to indicate that an annotation exists. Different markers can mean different types of annotations. Annotations types will be added as development continues.

8.1. Creating new annotations

Currently, text and image annotations are supported. Annotations come in the form of HTML and property list XML files.

First an image must be loaded. A user can then select "Create annotation mode" to start creating annotations.

Once you are in creating annotation mode, you can create a region of interest rectangle by pressing-and-dragging to show interested region. A dialog asking for which kind of annotation you are creating will show up once you release the the mouse button. Currently Corelyzer supports the following types of annotations.

  • Freefrom: a threaded discussion freeform annotation.

  • Clast: a structured annotation which keeps track of clastology information.

  • Sample Request: a front-end annotation for sample requests.

  • Property Values: a generic property-value pairs annotation. Default properties is defined in the dictionary file specified in the preferences panel.
