XDrawImageString(display, d, gc, x, y, string, length) Display *display; Drawable d; GC gc; int x, y; char *string; int length;
|display||Specifies the connection to the X server.|
|d||Specifies the drawable.|
|gc||Specifies the GC.|
|Specify the x and y coordinates, which are relative to the origin of the specified drawable and define the origin of the first character.|
|string||Specifies the character string.|
|length||Specifies the number of characters in the string argument.|
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:
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.
The function uses these GC components: plane-mask, foreground, background, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.
XDrawImageString() 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.|
