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:
Property | Default value |
---|---|
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.
