XmbDrawImageString(3) XLIB FUNCTIONS XmbDrawImageString(3)
NAME XmbDrawImageString, XwcDrawImageString, Xutf8DrawImageString - draw image text using a single font set
SYNTAX void XmbDrawImageString(Display *display, Drawable d, XFontSet font_set, GC gc, int x, int y, _Xconst char *string, int num_bytes);
void XwcDrawImageString(Display *display, Drawable d, XFontSet font_set, GC gc, int x, int y, _Xconst wchar_t *string, int num_wchars);
void Xutf8DrawImageString(Display *display, Drawable d, XFontSet font_set, GC gc, int x, int y, _Xconst char *string, int num_bytes);
ARGUMENTS d Specifies the drawable.
display Specifies the connection to the X server.
font_set Specifies the font set.
gc Specifies the GC.
num_bytes Specifies the number of bytes in the string argument.
num_wchars Specifies the number of characters in the string argument.
string Specifies the character string.
x
y Specify the x and y coordinates.
DESCRIPTION The XmbDrawImageString, XwcDrawImageString and Xutf8DrawImageString functions fill a destination rectangle with the background pixel defined in the GC and then paint the text with the foreground pixel. The filled rectangle is the rectangle returned to overall_logical_return by XmbTextExtents, XwcTextExtents or Xutf8TextExtents for the same text and XFontSet.
When the XFontSet has missing charsets, each unavailable character is drawn with the default string returned by XCreateFontSet. The behavior for an invalid codepoint is undefined.
The function Xutf8TextExtents is an extension introduced by The XFree86 Project, Inc., in their 4.0.2 release. Its presence is indicated by the macro X_HAVE_UTF8_STRING.
