Description
Sets the
number of units that the midpoint of the base shifts towards the vertex.
Syntax
GpStatus WINGDIPAPI GdipSetAdjustableArrowCapMiddleInset(
GpAdjustableArrowCap* cap,
REAL middleInset
);
PowerBASIC Syntax
DECLARE FUNCTION GdipSetAdjustableArrowCapMiddleInset _
BYVAL cap AS DWORD, _
BYVAL middleInset AS SINGLE _
) AS LONG
Parameters
cap
[in] Pointer
to the arrow cap.
middleInset
[in]
Single precision value that specifies the number of units that the midpoint of
the base shifts towards the vertex.
Remarks
The middle inset is the number of units that the midpoint
of the base shifts towards the vertex. A middle inset of zero results
in no shift — the base is
a straight line, giving the arrow a triangular shape. A positive (greater than
zero) middle inset results in a shift the specified number of units toward the
vertex — the base is an arrow shape that points toward the vertex, giving the
arrow cap a V-shape. A negative (less than zero) middle inset results in a shift
the specified number of units away from the vertex — the base becomes an arrow
shape that points away from the vertex, giving the arrow either a diamond shape
(if the absolute value of the middle inset is equal to the height) or distorted
diamond shape. If the middle inset is equal to or greater than the height of
the arrow cap, the cap does not appear at all. The value of the middle inset
affects the arrow cap only if the arrow cap is filled. The middle inset defaults
to zero when an AdjustableArrowCap object is constructed.
