virtual L_INT LAnnContainer::SetPolyFillMode(uPolyFillMode=ANNPOLYFILL_WINDING, uFlags=0)
Sets the value of the property that determines how a Polygonal annotation with crossing lines is filled.
The constant that specifies the polygon fill mode. Possible polygon fill mode values are:
Value | Meaning |
---|---|
ANNPOLYFILL_WINDING | [0] All pixels that are inside the resulting exterior lines are filled. |
ANNPOLYFILL_ALTERNATE | [1] The filled area includes the area between odd-numbered and even-numbered polygon sides on each scan line. |
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 LAnnContainer::GetSelectItems and LAnnotation::SetSelected 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. |
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function affects only polygon objects. For descriptions of the various types of objects and their properties, refer to Types of Annotations.
