XDrawImageString(3) XLIB FUNCTIONS XDrawImageString(3)NAMEXDrawImageString, XDrawImageString16 - draw image textSYNTAXint 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);ARGUMENTSd 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.DESCRIPTIONThe 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 fore- ground 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.DIAGNOSTICSBadDrawable 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.SEE ALSOXDrawString(3X11), XDrawText(3X11), XLoadFont(3X11), XTextExtents(3X11) Xlib - C Language X Interface X Version 11 libX11 1.2.1 XDrawImageString(3)
