Pointer Annotation Object - Raster imaging C++ Class Library Help

Pointer Annotation Object

The Pointer annotation object (ANNOBJECT_POINTER) is defined by two points with an arrow at the first point. With the automated functions, the user clicks and drags to specify the points in the current window.

The class for Pointer Annotation objects is LAnnPointer.

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

With low-level functions, you must provide the points that define the of the object. 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.

ROP2 code

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

Foreground color

Defaults to red. It can be changed using the LAnnXXX::SetForeColor function.

Fixed State

Defaults to not fixed. It can be changed using the LAnnXXX::SetFixed function.

Hyperlink

Defaults to ANNLINK_NONE. It can be changed using the LAnnotation::SetHyperlink function.

Tag (identifier)

Defaults to 0. It can be changed using the LAnnotation::SetTag function.

Window handle

Defaults to NULL or the handle inherited from the container.

User mode

Defaults to design mode or the mode inherited from the container.
