Point Annotation Object

Show in webframe

The Point annotation object (ANNOBJECT_POINT) is single point. With the automated functions, in design mode, each point is formed with a mouse click event.

The class for Point Annotation objects is LAnnPoint.

For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.

With low-level functions, you must define the point by calling LAnnPoint::SetPoints. Other applicable properties have the following defaults, which you can change:

Visible

Defaults to FALSE. It can be changed using the LAnnotation::SetVisible function.

Selected

Defaults to FALSE. It can be changed using the LAnnotation::SetSelected function.

Name

Defaults to an empty string. It can be changed using the LAnnotation::SetNameOptions function.

Line width

Defaults to 0.75 points. It can be changed using the LAnnXXX::SetLineWidth function. (Note that when displayed, the line must have a minimum width of 1 pixel.)

Line style

Defaults to solid. It can be changed using the LAnnXXX::SetLineStyle function.

Defaults to ANNROP2_COPY. It can be changed using the LAnnotation::SetROP2 function.
