NAME

6       XDrawImageString, XDrawImageString16 - draw image text
7

SYNTAX

9       int XDrawImageString(Display *display, Drawable d, GC gc, int x, int y,
10              _Xconst char *string, int length);
11
12       int XDrawImageString16(Display *display, Drawable d, GC gc, int x,  int
13              y, _Xconst XChar2b *string, int length);
14

ARGUMENTS

16       d         Specifies the drawable.
17
18       display   Specifies the connection to the X server.
19
20       gc        Specifies the GC.
21
22       length    Specifies the number of characters in the string argument.
23
24       string    Specifies the character string.
25
26       x
27       y         Specify  the  x  and y coordinates, which are relative to the
28                 origin of the specified drawable and define the origin of the
29                 first character.

DESCRIPTION

32       The  XDrawImageString16  function is similar to XDrawImageString except
33       that it uses 2-byte or 16-bit characters.  Both functions also use both
34       the foreground and background pixels of the GC in the destination.
35
36       The effect is first to fill a destination rectangle with the background
37       pixel defined in the GC and then to paint the text with the  foreground
38       pixel.  The upper-left corner of the filled rectangle is at:
39
40       [x, y - font-ascent]
41
42       The width is:
43
44       overall-width
45
46       The height is:
47
48       font-ascent + font-descent
49
50       The  overall-width,  font-ascent,  and font-descent are as would be re‐
51       turned by XQueryTextExtents using gc  and  string.   The  function  and
52       fill-style  defined in the GC are ignored for these functions.  The ef‐
53       fective function is GXcopy, and the effective fill-style is FillSolid.
54
55       For fonts defined with 2-byte matrix indexing and  used  with  XDrawIm‐
56       ageString, each byte is used as a byte2 with a byte1 of zero.
57
58       Both  functions  use these GC components: plane-mask, foreground, back‐
59       ground, font, subwindow-mode, clip-x-origin, clip-y-origin,  and  clip-
60       mask.
61
62       XDrawImageString   and  XDrawImageString16  can  generate  BadDrawable,
63       BadGC, and BadMatch errors.
64

DIAGNOSTICS

66       BadDrawable
67                 A value for a Drawable argument does not name a defined  Win‐
68                 dow or Pixmap.
69
70       BadGC     A value for a GContext argument does not name a defined GCon‐
71                 text.
72
73       BadMatch  An InputOnly window is used as a Drawable.
74
75       BadMatch  Some argument or pair of arguments has the correct  type  and
76                 range  but  fails  to match in some other way required by the
77                 request.
78

NOTES

80       Unlike XDrawString and XDrawString16, these functions send no more than
81       255 characters at a time to the server.  When the total number of char‐
82       acters to be sent is larger than 255, these functions split the  string
83       into  chunks  up  to  255  characters.  After sending each chunk, these
84       functions query the server to determine the actual text extent.
