NotateXpress 13 for ActiveX - User Guide > How To > Annotate Programmatically > Create or Delete a Layer |
NotateXpress™ maintains annotations on layers. Layers act like transparent overlays to the image, and can be used to separate annotations. For example, a separate annotation layer could be established for each different end-user (e.g. legal department comments vs. marketing department comments on a proposal), or for each different function (e.g. plumbing notes vs. wiring notes on a house blueprint). Layers can be viewed simultaneously, or alone. (For example, view only legal department comment layer, or view legal department and marketing department comment layers).
Call CreateLayer to create a new annotation layer. Alternatively, the application can copy an existing layer by calling the CopyLayer and PasteLayer methods.

Make sure that NotateXpress has an associated valid ImagXpress Client prior to creating a layer. |
Call DeleteLayer to delete a layer. All annotations on the deleted layer are also deleted.
