+.SH DESCRIPTION
+.EQ
+delim %%
+.EN
+.ZN XDrawArc
+draws a single circular or elliptical arc, and
+.ZN XDrawArcs
+draws multiple circular or elliptical arcs.
+Each arc is specified by a rectangle and two angles.
+The center of the circle or ellipse is the center of the
+rectangle, and the major and minor axes are specified by the width and height.
+Positive angles indicate counterclockwise motion,
+and negative angles indicate clockwise motion.
+If the magnitude of angle2 is greater than 360 degrees,
+.ZN XDrawArc
+or
+.ZN XDrawArcs
+truncates it to 360 degrees.
+.LP
+For an arc specified as %[ ~x, ~y, ~width , ~height, ~angle1, ~angle2 ]%,
+the origin of the major and minor axes is at
+% [ x +^ {width over 2} , ~y +^ {height over 2} ]%,
+and the infinitely thin path describing the entire circle or ellipse
+intersects the horizontal axis at % [ x, ~y +^ {height over 2} ]% and
+% [ x +^ width , ~y +^ { height over 2 }] %
+and intersects the vertical axis at % [ x +^ { width over 2 } , ~y ]% and
+% [ x +^ { width over 2 }, ~y +^ height ]%.
+These coordinates can be fractional
+and so are not truncated to discrete coordinates.
+The path should be defined by the ideal mathematical path.
+For a wide line with line-width lw,
+the bounding outlines for filling are given
+by the two infinitely thin paths consisting of all points whose perpendicular
+distance from the path of the circle/ellipse is equal to lw/2
+(which may be a fractional value).
+The cap-style and join-style are applied the same as for a line
+corresponding to the tangent of the circle/ellipse at the endpoint.
+.LP
+For an arc specified as % [ ~x, ~y, ~width, ~height, ~angle1, ~angle2 ]%,
+the angles must be specified
+in the effectively skewed coordinate system of the ellipse (for a
+circle, the angles and coordinate systems are identical). The
+relationship between these angles and angles expressed in the normal
+coordinate system of the screen (as measured with a protractor) is as
+follows:
+.LP
+.Ds
+% roman "skewed-angle" ~ = ~ atan left ( tan ( roman "normal-angle" )
+ * width over height right ) +^ adjust%
+.De
+.LP
+The skewed-angle and normal-angle are expressed in radians (rather
+than in degrees scaled by 64) in the range % [ 0 , ~2 pi ]% and where atan
+returns a value in the range % [ - pi over 2 , ~pi over 2 ] %
+and adjust is:
+.LP
+.TS
+l l.
+%0% for normal-angle in the range % [ 0 , ~pi over 2 ]%
+%pi% for normal-angle in the range % [ pi over 2 , ~{3 pi} over 2 ]%
+%2 pi% for normal-angle in the range % [ {3 pi} over 2 , ~2 pi ]%
+.TE
+.LP
+For any given arc,
+.ZN XDrawArc
+and
+.ZN XDrawArcs
+do not draw a pixel more than once.
+If two arcs join correctly and if the line-width is greater than zero
+and the arcs intersect,
+.ZN XDrawArc
+and
+.ZN XDrawArcs
+do not draw a pixel more than once.
+Otherwise,
+the intersecting pixels of intersecting arcs are drawn multiple times.
+Specifying an arc with one endpoint and a clockwise extent draws the same pixels
+as specifying the other endpoint and an equivalent counterclockwise extent,
+except as it affects joins.
+.LP
+If the last point in one arc coincides with the first point in the following
+arc, the two arcs will join correctly.
+If the first point in the first arc coincides with the last point in the last
+arc, the two arcs will join correctly.
+By specifying one axis to be zero, a horizontal or vertical line can be
+drawn.
+Angles are computed based solely on the coordinate system and ignore the
+aspect ratio.
+.LP
+Both functions use these GC components:
+function, plane-mask, line-width, line-style, cap-style, join-style,
+fill-style, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.
+They also use these GC mode-dependent components:
+foreground, background, tile, stipple, tile-stipple-x-origin,
+tile-stipple-y-origin, dash-offset, and dash-list.
+.LP
+.ZN XDrawArc
+and
+.ZN XDrawArcs
+can generate
+.ZN BadDrawable ,
+.ZN BadGC ,
+and
+.ZN BadMatch
+errors.
+.SH STRUCTURES
+The
+.ZN XArc
+structure contains:
+.LP
+.EX
+typedef struct {
+ short x, y;
+ unsigned short width, height;
+ short angle1, angle2; /\&* Degrees * 64 */
+} XArc;
+.EE
+.LP
+All x and y members are signed integers.
+The width and height members are 16-bit unsigned integers.
+You should be careful not to generate coordinates and sizes
+out of the 16-bit ranges, because the protocol only has 16-bit fields
+for these values.
+.SH DIAGNOSTICS
+.TP 1i
+.ZN BadDrawable
+A value for a Drawable argument does not name a defined Window or Pixmap.
+.TP 1i
+.ZN BadGC
+A value for a GContext argument does not name a defined GContext.
+.TP 1i
+.ZN BadMatch
+An
+.ZN InputOnly
+window is used as a Drawable.
+.TP 1i
+.ZN BadMatch
+Some argument or pair of arguments has the correct type and range but fails
+to match in some other way required by the request.
