XDrawImageString(3X11)XDrawImageString(3X11)NAME
XDrawImageString, XDrawImageString16 - draw image text
SYNOPSIS
XDrawImageString(display, d, gc, x, y, string, length)
Display *display;
Drawable d;
GC gc;
int x, y;
char *string;
int length;
XDrawImageString16(display, d, gc, x, y, string, length)
Display *display;
Drawable d;
GC gc;
int x, y;
XChar2b *string;
int length;
ARGUMENTS
Specifies the drawable. Specifies the connection to the X server.
Specifies the GC. Specifies the number of characters in the string
argument. Specifies the character string. Specify the x and y coordi‐
nates, which are relative to the origin of the specified drawable and
define the origin of the first character.
DESCRIPTION
The XDrawImageString16 function is similar to 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.
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:
[x, y - font-ascent]
The width is:
overall-width
The height is:
font-ascent + font-descent
The overall-width, font-ascent, and font-descent are as would be
returned by XQueryTextExtents using gc and string. The function and
fill-style defined in the GC are ignored for these functions. The
effective function is GXcopy, and the effective fill-style is Fill‐
Solid.
For fonts defined with 2-byte matrix indexing and used with XDrawIm‐
ageString, each byte is used as a byte2 with a byte1 of zero.
Both functions use these GC components: plane-mask, foreground, back‐
ground, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-
mask.
XDrawImageString and XDrawImageString16 can generate BadDrawable,
BadGC, and BadMatch errors.
DIAGNOSTICS
A value for a Drawable argument does not name a defined Window or
Pixmap. A value for a GContext argument does not name a defined GCon‐
text. An InputOnly window is used as a Drawable. Some argument or
pair of arguments has the correct type and range but fails to match in
some other way required by the request.
