The ANNPOINTEROPTIONS structure contains information about the pointer options of an ANNOBJECT_POINTER or ANNOBJECT_AUTOMATION object.
|uStructSize||Size of this structure. Use sizeof(ANNPOINTEROPTIONS).|
|uFlags||Flag that indicates which fields are valid. Possible values are one or more of the following constants "or"ed together:|
|ANNPOINTER_HEAD||[0x0001] nPointerHeadM and nPointerHeadB fields are valid.|
|ANNPOINTER_ALL||[0x0001] All fields are valid.|
|nPointerHeadM||Value that determines the length of the pointer head (along with nPointerHeadB).|
|nPointerHeadB||Value that determines the length of the pointer head (along with nPionterHeadM).|
|nReserved||Reserved for future use. Pass 0.|
For an ANNOBJECT_POINTER object, the length of the head is determined as a linear function of the line width of the object as follow:
LengthOfHead = LineWidth * nPointerHeadM + nPointerHeadB
Setting nPointerHeadM to 1 or more causes the pointer head length to change as the line width changes. Setting nPointerHeadM to 0, and nPointerHeadB to a non-zero value causes the pointer head length to stay constant, regardless of the line width.
When you create an ANNOBJECT_POINTER object in the automation mode, the values for nPointerHeadM and nPointerHeadB are being obtained from the automation object.
