The rectangle annotation object (ANNOBJECT_RECT) is a simple rectangle. With the automated functions, the user clicks and drags to specify the rectangle in the current window.
With low-level functions, you must define the size and position of the rectangle. 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. |
|
Fill pattern |
Defaults to solid. It can be changed using the L_AnnSetFillPattern function. |
|
Fill mode |
Defaults to transparent. It can be changed using the L_AnnSetFillMode function. Before calling this function, enable the alpha background fill mode by calling the L_AnnSetOptions function. |
|
Foreground color |
Defaults to red. It can be changed using the L_AnnSetForeColor function. |
