.IP \fIy\fP 1i
|

Specify the x and y coordinates\*(Xy.
|
|
.SH DESCRIPTION
|
|
Each character image, as defined by the font in the GC, is treated as an
|
|
additional mask for a fill operation on the drawable.
|
|
The drawable is modified only where the font character has a bit set to 1.
|
|
For fonts defined with 2-byte matrix indexing
|
|
and used with
|
|
.ZN XDrawString16 ,
|
|
each byte is used as a byte2 with a byte1 of zero.
|
|
.LP
|
|
Both functions use these GC components:
|
|
function, plane-mask, fill-style, font, 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,
|
|
and tile-stipple-y-origin.
|
|
.LP
|
|
.ZN XDrawString
|
|
and
|
|
.ZN XDrawString16
|
|
can generate
|
|
.ZN BadDrawable ,
|
|
.ZN BadGC ,
|
|
and
|
|
.ZN BadMatch
|
|
errors.
|
|
.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.
