Line Annotation Object

Show in webframe

The line annotation object (ANNOBJECT_LINE) is a simple line. With the automated functions, the line is started on a mouse-down event and completed on a mouse-up event.

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

Note: You can not create a line of two points which they are the same.
