Pointer Annotation Object

Show in webframe

(Document and Medical Imaging toolkits)

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.

With low-level functions, you must provide the points that define the points of the object. Other applicable properties have the following defaults, which you can change:

 

Visible

Defaults to FALSE. It can be changed using the L_AnnSetVisible function.

Selected

Defaults to FALSE. It can be changed using the L_AnnSetSelected function.

Name

Defaults to an empty string. It can be changed using the L_AnnSetNameOptions function.

Line width

Defaults to 0.75 points. It can be changed using the L_AnnSetLineWidth 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 L_AnnSetLineStyle function.

ROP2 code

Defaults to ANNROP2_COPY. It can be changed using the L_AnnSetROP2 function.

Foreground color

Defaults to red. It can be changed using the L_AnnSetForeColor function.

Fixed State

Defaults to not fixed. It can be changed using the L_AnnSetFixed function.

Hyperlink

Defaults to None. It can be changed using the L_AnnSetHyperlink function.

Tag (identifier)

Defaults to 0. It can be changed using the L_AnnSetTag function.

Window handle

Defaults to NULL or the handle inherited from the container. It can be changed for all objects using the L_AnnSetWnd function.

User mode

Defaults to design mode or the mode inherited from the container. It can be changed for all objects using the L_AnnSetUserMode function.
