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_90

[90] Rotate the text 90 degrees counter clockwise.

[180] Rotate the text 180 degrees counter clockwise.

TEXTROTATE_270

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 LAnnotation::IsSelected and LAnnotation::SetSelected functions.

ANNFLAG_NOTTHIS

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.
