Text Pointer Annotation Object

(Document and Medical Imaging toolkits)

The Text Pointer annotation object (ANNOBJECT_TEXTPOINTER) is a rectangle with a line that starts from one of the four corners. The other endpoint of the line can be moved to point to anything on the underlying image. The rectangle contains a character string with font properties. The text will wrap on word breaks within the object's specified rectangle.

With the automated functions, the user clicks and drag to specify the rectangle in the current window. After letting up on the mouse button, the rectangle is specified. Moving the mouse now specifies the line, with a final mouse click defining the line.

For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.

With low-level functions, you must specify the rectangle that contains the text, and the pointer endpoint of the line. See L_AnnSetPoints for more details. 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 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.
Font size	Defaults to 10 point, translated with a scaling factor of 1. It can be changed using the L_AnnSetFontSize function.
Font underline	Defaults to FALSE. It can be changed using the L_AnnSetFontUnderline function.
Font strikethrough	Defaults to FALSE. It can be changed using the L_AnnSetFontStrikeThrough function.
Font italic	Defaults to FALSE. It can be changed using the L_AnnSetFontItalic function.
Font bold	Defaults to FALSE. It can be changed using the L_AnnSetFontBold function.

Text	Defaults to "AaBbYyZz". It can be changed using the L_AnnSetText function.
Text Displayed	Defaults to Show text. It can be changed using L_AnnSetTextOptions.
Text Color	Defaults to red (RGB(255,0,0). It can be changed using L_AnnSetTextOptions.
Text Alignment	Defaults to left alignment. It can be changed using the L_AnnSetTextAlign function.
Text Rotate	Defaults to no rotation. It can be changed using the L_AnnSetTextRotate function.
Text Pointer	The pointer part of the text pointer does not move when the object moves. It can be changed using the L_AnnSetTextPointerFixed function.
Expand Tokens	Defaults to expand tokens. It can be changed using the L_AnnSetTextExpandTokens 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.
Fixed State	Defaults to not fixed. It can be changed using the L_AnnSetFixed function.

* Note: These features must be enabled using the L_AnnSetOptions function.
