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_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. |
You use the Windows COLORREF data type to specify the color. For example, you can use the LBitmapBase::GetPixelColor function or the Windows RGB macro to get a color value.
Win32, x64.
For an example, refer to LAnnText::GetBackColor.
