>>TITLE XLoadFont CH06
Font

Display	*display = Dsp;
char	*name = "xtfont1";
>>SET startup fontstartup
>>SET cleanup fontcleanup
>>ASSERTION Good A
When 
.A name
is a NULL terminated string in ISO Latin-1 encoding,
then
a call to xname
loads the specified font and returns its font ID.
>>STRATEGY
For each xtest font:
  Load font.
  Make some simple checks to see if a font ID is returned.
>>CODE
Font	font;
int 	i;
char	fname[64];

	for (i = 0; i < XT_NFONTS; i++) {
		sprintf(fname, "xtfont%d", i);
		trace("Loading font %s", fname);
		name = fname;

		font = XCALL;

		if (geterr() != Success) {
			report("font %s could not be loaded", fname);
			report("Check that xtest fonts have been installed");
			FAIL;
		} else if (font == 0 || (font & 0xc0000000)) {
			report("An invalid font ID was returned");
			FAIL;
		} else
			CHECK;
	}
	CHECKPASS(XT_NFONTS);

>>ASSERTION Good A
The font ID returned by a call to xname is usable 
on any GC created for any screen of the display.
>>STRATEGY
For each visual supported for the default screen:
  Load font "xtfont1".
  Create window.
  Create GC for window.
  Set font component in GC to loaded font.
  Draw string with single character.
  Pixmap verify.
Note: this tests the GC's for the default screen. 
To test for other screens, re-run the test suite with XT_DISPLAY set 
to number of required screen.
>>CODE
XVisualInfo	*vp;
Font	font;
char	*fname = "xtfont1";
Drawable d;
GC	gc;

	for (resetvinf(VI_WIN_PIX); nextvinf(&vp); ) {
		name = fname;

		font = XCALL;

		if (geterr() != Success) {
			/* Already done after calling XLoadFont */
			report("font %s could not be loaded", fname);
			report("Check that xtest fonts have been installed");
			FAIL;
		} else {
			d = makewin(display, vp);
			gc = makegc(display, d);
			XSetFont(display, gc, font);
			XDrawString(display, d, gc, 20, 20, "z", 1);
			PIXCHECK(display, d);
			dclear(display, d);
			XUnloadFont(display, font);
		}
	}
	CHECKPASS(nvinf());

>>ASSERTION Good A
Upper and lower case characters in the
.A name
argument refer to the same font.
>># The name arg is case insensitive.
>>STRATEGY
Try series of name differing only in case.
Font ID is different each time so have to..
Draw string and save result in original font.
Verify that font returned using each name draws same string.
