XFillArc()XFillArc()NameXFillArc – fill an arc.
Synopsis
XFillArc(display, drawable, gc, x, y, width, height, angle1, angle2)
Display *display;
Drawable drawable;
GC gc;
int x, y;
unsigned int width, height;
int angle1, angle2;
Arguments
display Specifies a connection to an X server; returned from
XOpenDisplay().
drawable Specifies the drawable.
gc Specifies the graphics context.
x Specify the x and y coordinates of the upper-left corner of
y the bounding box containing the arc, relative to the origin
of the drawable.
width Specify the width and height in pixels. These are the major
height and minor axes of the arc.
angle1 Specifies the start of the arc relative to the three-o'clock
position from the center. Angles are specified in 64ths of
degrees.
angle2 Specifies the path and extent of the arc relative to the
start of the arc. Angles are specified in 64ths of degrees.
DescriptionXFillArc() draws a filled arc. The x, y, width, and height arguments
specify the bounding box for the arc. See XDrawArc() for the descrip‐
tion of how this bounding box is used to compute the arc. Some, but
not all, of the pixels drawn with XDrawArc() will be drawn by XFil‐
lArc() with the same arguments. See XFillRectangle() for an example of
the differences in pixels drawn by the draw and fill routines.
The arc forms one boundary of the area to be filled. The other bound‐
ary is determined by the arc_mode in the GC. If the arc_mode in the GC
is ArcChord, the single line segment joining the endpoints of the arc
is used. If ArcPieSlice, the two line segments joining the endpoints
of the arc with the center point are used.
XFillArc() uses these graphics context components: function,
plane_mask, fill_style, arc_mode, subwindow_mode, clip_x_origin,
clip_y_origin, and clip_mask. This function also uses these graphics
context mode-dependent components: foreground, background, tile, stip‐
ple, ts_x_origin, and ts_y_
origin.

Text, and Chapter 5, The Graphics Context.
