XDrawImageString 3X11 __xorgversion__ XLIB FUNCTIONS XDrawImageString XDrawImageString16 draw image text int XDrawImageString ( Display *display , Drawable d , GC gc , int x , int y , char *string , int length ); int XDrawImageString16 ( Display *display , Drawable d , GC gc , int x , int y , XChar2b *string , int length ); 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. and define the origin of the first character x y Specify the x and y coordinates, which are relative to the origin of the specified drawable. 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  FillSolid . For fonts defined with 2-byte matrix indexing and used with  XDrawImageString , each byte is used as a byte2 with a byte1 of zero. Both functions use these GC components: plane-mask, foreground, background, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.  XDrawImageString  and  XDrawImageString16  can generate  BadDrawable ,  BadGC , and  BadMatch  errors.  BadDrawable  A value for a Drawable argument does not name a defined Window or Pixmap.  BadGC  A value for a GContext argument does not name a defined GContext.  BadMatch  An  InputOnly  window is used as a Drawable.  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.
