Check to make sure the extents are valid. Also make sure the overall extents are equal to the combined extents of the characters. Make sure the returned status is good. >>CODE Display *dpy; char *plocale; char *fontset; char *font_list; XFontSet pfs; char *defstr; int missing_cnt; char **missing_chars; XFontSetExtents *ext; int escapement; int nbytes,nchars,maxescape; Status status; XRectangle ink[MAX_CHARS]; XRectangle logical[MAX_CHARS]; XRectangle overall_ink; XRectangle overall_logical; resetlocale(); dpy = Dsp; while(nextlocale(&plocale)) { if (locale_set(plocale)) CHECK; else { report("Couldn't set locale."); FAIL; continue; } /* cycle through the fontsets */ resetfontset(); while(nextfontset(&font_list)) { pfs = XCreateFontSet(dpy,font_list,&missing_chars, &missing_cnt,&defstr); if(pfs == NULL) { report("XCreateFontSet unable to create fontset, %s", font_list); FAIL; } else { trace("Created Font Set %s", font_list); font_set = pfs; ext = XExtentsOfFontSet(pfs); if(ext == NULL) { report("Extents of fontset %s returns null record for locale, %s", font_list,plocale); FAIL; } else { int j; trace("Extents for fontset, %s, in locale %s:", font_list,plocale); trace(" Max Ink Extents - (%d,%d) w=%d, h=%d", ext->max_ink_extent.x, ext->max_ink_extent.y, ext->max_ink_extent.width, ext->max_ink_extent.height); trace(" Max Logical Extents - (%d,%d) w=%d, h=%d", ext->max_logical_extent.x, ext->max_logical_extent.y, ext->max_logical_extent.width, ext->max_logical_extent.height); maxescape = 0; for(j=0;j (int)overall_ink.width) || (hcnt > (int)overall_ink.height)) { report("Ink extents of chars (%d,%d) is greater than overall extents (%d,%d) for string %s", wcnt,hcnt, overall_ink.width, overall_ink.height, test_str_list[j]); FAIL; } else CHECK; wcnt = 0; hcnt = logical[0].height; trace("---Logical [overall] wid=%d, ht=%d", overall_ink.width, overall_ink.height); for(k=0;k (int)overall_logical.width) || (hcnt > (int)overall_logical.height)) { report("Logical extents of chars (%d,%d) is greater than overall extents (%d,%d) for string %s", wcnt,hcnt, overall_logical.width, overall_logical.height, test_str_list[j]); FAIL; } else CHECK; if((overall_ink.width > overall_logical.width) || (overall_ink.height > overall_logical.height)) { report("Ink extents are greater than logical extents of fontset, %s in locale %s", font_list,plocale); FAIL; } else CHECK; } } } } XFreeFontSet(dpy,pfs); XFreeStringList(missing_chars); } } } CHECKPASS(nlocales()+3*MAX_TEST_STR*nlocales()*nfontset());
