+.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. +.SH "SEE ALSO" +XDrawLine(3X11), +XDrawPoint(3X11), +XDrawRectangle(3X11) +.br +\fI\*(xL\fP -- cgit v1.2.3
