Rectangle Annotation Object

(Document and Medical Imaging toolkits)

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.
Background color	Defaults to white. It can be changed using the L_AnnSetBackColor function. The default does not affect highlight, redaction, or note objects.
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.
