ARGUMENTS$Header: d.a,v 1.1 88/02/26 10:04:25 mento Exp $d 1iSpecifies the drawable. $Header: display.a,v 1.1 88/02/26 10:26:29 mento Exp $display 1iSpecifies the connection to the X server. $Header: gc.a,v 1.2 88/05/09 11:20:34 mento Exp $gc 1iSpecifies the GC. $Header: mode.a,v 1.4 88/05/18 07:53:37 mento Exp $mode 1iSpecifies the coordinate mode. You can pass .ZN CoordModeOrigin or .ZN CoordModePrevious . $Header: npoints.a,v 1.1 88/02/26 10:29:46 mento Exp $npoints 1iSpecifies the number of points in the array. $Header: points.a,v 1.1 88/02/26 10:30:33 mento Exp $points 1iSpecifies an array of points. $Header: xy_point.a,v 1.1 88/02/26 10:32:57 mento Exp $x 1i.ns
y 1iSpecify the x and y coordinates where you want the point drawn.DESCRIPTION$Header: XPoint.d,v 1.4 88/06/11 07:52:15 mento Exp $
The .ZN XDrawPoint function uses the foreground pixel and function components of the GC to draw a single point into the specified drawable; .ZN XDrawPoints draws multiple points this way. .ZN CoordModeOrigin treats all coordinates as relative to the origin, and .ZN CoordModePrevious treats all coordinates after the first as relative to the previous point. .ZN XDrawPoints draws the points in the order listed in the array.Both functions use these GC components: function, plane-mask, foreground, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.
.ZN XDrawPoint can generate .ZN BadDrawable , .ZN BadGC , and .ZN BadMatch errors. .ZN XDrawPoints can generate .ZN BadDrawable , .ZN BadGC , .ZN BadMatch , and .ZN BadValue errors.
STRUCTURESThe .ZN XPoint structure contains:.Ds 0 .TA .5i typedef struct { short x, y; } XPoint; .De
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.
DIAGNOSTICS$Header: baddrawable.e,v 1.1 87/09/04 08:22:59 mento Exp $1i .ZN BadDrawable A value for a Drawable argument does not name a defined Window or Pixmap. $Header: badgc.e,v 1.1 87/09/04 08:23:02 mento Locked $
1i .ZN BadGC A value for a GContext argument does not name a defined GContext. $Header: badmatch1.e,v 1.3 87/09/09 18:18:54 mento Exp $
1i .ZN BadMatch An .ZN InputOnly window is used as a Drawable. $Header: badmatch2.e,v 1.3 87/09/11 11:53:42 mento Exp $
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. $Header: badvalue.e,v 1.1 87/09/04 08:23:19 mento Exp $
1i .ZN BadValue Some numeric value falls outside the range of values accepted by the request. Unless a specific range is specified for an argument, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this error.
