Description
int
imagefilledarc ( resource
image, int cx, int cy, int w, int h, int s, int e, int col,
int style)
imagefilledarc() draws a partial
ellipse centered at cx, cy (top left is 0, 0) in the
image represented by image.
W and h specifies the ellipse's width and
height respectively while the start and end points are
specified in degrees indicated by the
s and e
arguments. style is a
bitwise OR of the following possibilities:
-
-
-
-
IMG_ARC_PIE and
IMG_ARC_CHORD are mutually exclusive;
IMG_ARC_CHORD just connects the starting and
ending angles with a straight line, while
IMG_ARC_PIE produces a rounded edge.
IMG_ARC_NOFILL indicates that the arc or
chord should be outlined, not filled.
IMG_ARC_EDGED, used together with
IMG_ARC_NOFILL, indicates that the beginning and ending
angles should be connected to the center - this is a good way
to outline (rather than fill) a 'pie slice'.
