|
|
The
|
|
.ZN XDrawImageString16
|
|
function is similar to
|
|
.ZN XDrawImageString
|
|
except that it uses 2-byte or 16-bit characters.
|
|
Both functions also use both the foreground and background pixels
|
|
of the GC in the destination.
|
|
.LP
|
|
The effect is first to fill a
|
|
destination rectangle with the background pixel defined in the GC and then
|
|
to paint the text with the foreground pixel.
|
|
The upper-left corner of the filled rectangle is at:
|
|
.LP
|
|
.Ds
|
|
[x, y \- font-ascent]
|
|
.De
|
|
.LP
|
|
The width is:
|
|
.LP
|
|
.Ds
|
|
overall-width
|
|
.De
|
|
.LP
|
|
The height is:
|
|
.LP
|
|
.Ds
|
|
font-ascent + font-descent
|
|
.De
|
|
.LP
|
|
The overall-width, font-ascent, and font-descent
|
|
are as would be returned by
|
|
.ZN XQueryTextExtents
|
|
using gc and string.
|
|
The function and fill-style defined in the GC are ignored for these functions.
|
|
The effective function is
|
|
.ZN GXcopy ,
|
|
and the effective fill-style is
|
|
.ZN FillSolid .
|
|
.LP
|
|
For fonts defined with 2-byte matrix indexing
|
|
and used with
|
|
.ZN XDrawImageString ,
|
|
each byte is used as a byte2 with a byte1 of zero.
|
|
.LP
|
|
Both functions use these GC components:
|
|
plane-mask, foreground, background, font, subwindow-mode, clip-x-origin,
|
|
clip-y-origin, and clip-mask.
|
|
.LP
|
|
.ZN XDrawImageString
|
|
and
|
|
.ZN XDrawImageString16
|
|
can generate
|
|
.ZN BadDrawable ,
|
|
.ZN BadGC ,
|
|
and
|
|
.ZN BadMatch
|
|
errors.
