.SH DESCRIPTION
|
|
The
|
|
.ZN XDrawRectangle
|
|
and
|
|
.ZN XDrawRectangles
|
|
functions draw the outlines of the specified rectangle or rectangles as
|
|
if a five-point
|
|
.ZN PolyLine
|
|
protocol request were specified for each rectangle:
|
|
.IP
|
|
[x,y] [x+width,y] [x+width,y+height] [x,y+height] [x,y]
|
|
.LP
|
|
For the specified rectangle or rectangles,
|
|
these functions do not draw a pixel more than once.
|
|
.ZN XDrawRectangles
|
|
draws the rectangles in the order listed in the array.
|
|
If rectangles intersect,
|
|
the intersecting pixels are drawn multiple times.
|
|
.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 XDrawRectangle
|
|
and
|
|
.ZN XDrawRectangles
|
|
can generate
|
|
.ZN BadDrawable ,
|
|
.ZN BadGC ,
|
|
and
|
|
.ZN BadMatch
|
|
errors.
|
|
.SH STRUCTURES
|
|
The
|
|
.ZN XRectangle
|
|
structure contains:
|
|
.LP
|
|
.Ds 0
|
|
.TA .5i
|
|
.ta .5i
|
|
typedef struct {
|
|
short x, y;
|
|
unsigned short width, height;
|
|
} XRectangle;
|
|
.De
|
|
.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.
