XDrawImageString, XDrawImageString16 - draw image text
SYNTAX
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
d Specifies the drawable.
display Specifies the connection to the X server.
gc Specifies the GC.
length Specifies the number of characters in the string argument.
string Specifies the character string.
x
y Specify the x and y coordinates, which are relative to the
origin of the specified drawable and define the origin of the
first character.
DESCRIPTION
The function is similar to except that it uses 2-byte or 16-bit charac‐
ters. Both functions also use both the foreground and background pix‐
els 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 using gc and string. The function and fill-style defined
in the GC are ignored for these functions. The effective function is
and the effective fill-style is
For fonts defined with 2-byte matrix indexing and used with 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.
and can generate and 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 GContext.
An 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.
