The Curve annotation object (ANNOBJECT_CURVE) is a sequence of points that are joined by cubic polynomials such that adjacent polynomials are continuous at the first and second derivates. The result is a smooth, continuous curve going through all the points.
With the automated functions, each curve is formed with a mouse click, and the object is completed on a double click.
With low-level functions, you must provide the points that define the shape 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.|
|Nodes||Defaults to displaying every node. It can be changed using the L_AnnSetNodes 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.|
