L_AnnSetLineStyle

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_AnnSetLineStyle(hObject, uLineStyle, uFlags)

HANNOBJECT hObject;	/* handle to the annotation object */
L_UINT uLineStyle;	/* constant that specifies the line style */
L_UINT uFlags;	/* flags that determine which objects to process */

Sets the line style of one or more annotation objects. This function is available in the Document/Medical Toolkits.

Parameter	Description
hObject	Handle to the annotation object.
uLineStyle	The constant that specifies the line style. Possible line style values are:
	Value	Meaning
	ANNLINE_SOLID	[0] Solid line
	ANNLINE_DASH	[1] Dashed line
	ANNLINE_DOT	[2] Dotted line
	ANNLINE_DASHDOT	[3] Dash dot line
	ANNLINE_DASHDOTDOT	[4] Dash dot dot line
	ANNLINE_NULL	[5] No line
	Note: Windows displays all lines greater than 1 pixel as solid.
	To see the possible line styles, refer to Illustration of Line Styles for Annotations.
uFlags	Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( \| ). The following are valid values:
	Value	Meaning
	0	Process only the specified object.
	ANNFLAG_SELECTED	[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the L_AnnGetSelected and L_AnnSetSelected functions.
	ANNFLAG_NOTTHIS	[0x0004] Process only one level of objects within the specified container, not the container itself. If there are containers within the container, they are modified, but the objects within them are not.
	ANNFLAG_RECURSE	[0x0008] Process objects within a container, and within any subcontainers, down to any level.
	ANNFLAG_NOTCONTAINER	[0x0002] (Used with ANNFLAG_RECURSE) Process objects within containers, not the containers themselves.
	ANNFLAG_NOINVALIDATE	[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.
	ANNFLAG_CHECKMENU	[0x0020] Process objects only if the ANNAUTOTEXT_MENU_LINE menu item has been selected.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function applies to multiple and selected objects based on values of the uFlags parameter.

This function does not affect objects that do not have this property or that do not let you change the property. For descriptions of the various types of objects and their properties, refer to Types of Annotations.
