Handle to the annotation object. |
|
|
uTextRotate |
Value that indicates whether the text of an annotation object is rotated, and if so, then by how many degrees. Possible values are: |
|
|
|
Value |
Meaning |
|
|
TEXTROTATE_0 |
[0] Do not rotate the text. |

|
|
TEXTROTATE_270 |
[270] Rotate the text 270 degrees counter clockwise. |

uFlags |

|
|
|
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_TEXT menu item has been selected. |
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |

Comments
This function sets a value that indicates whether the text of certain annotation objects that display text will be rotated. The function is valid only for the following annotation objects:
ANNOBJECT_AUTOMATION
ANNOBJECT_NOTE
ANNOBJECT_TEXTPOINTER
Calling this function on an object other than those listed above will return ERROR_FEATURE_NOT_SUPPORTED. Note that the ANNOBJECT_TEXT object does not support text rotation because it can be rotated ANY angle by calling L_AnnRotate.
