Description
Creates an adjustable arrow line cap with the specified height and
width. The arrow line cap can be filled or nonfilled. The middle inset defaults
to zero.
Syntax
GpStatus WINGDIPAPI
GdipCreateAdjustableArrowCap(
REAL height,
REAL width,
BOOL isFilled,
GpAdjustableArrowCap **cap
);
PowerBASIC Syntax
DECLARE FUNCTION GdipCreateAdjustableArrowCap _
BYVAL nHeight
AS SINGLE, _
BYVAL nWidth AS
SINGLE, _
BYVAL isFilled
AS LONG, _
BYREF cap AS
DWORD _
) AS LONG
Parameters
height
[in] Single precision number that specifies the length, in
units, of the arrow from its base to its point.
width
[in] Single precision number that specifies the distance, in
units, between the corners of the base of the arrow.
isFilled
[in] Boolean value (TRUE or FALSE) that specifies whether the
arrow is filled.
cap
[out] Pointer to a variable that receives a pointer to the new
created adjustable arrow line cap.
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.
