Adding fonts with very large size in x11

Question

I want to add fonts in my x11 application. I tried adding but am finding difficulty in changing its size using the font name. When I changed the font's points and pixel, it turned into very small fonts. Can anyone help in getting the large font name.

Here, I have attached sample code which I tried,

#include 
#include 
#include 
#include 

int main(void){
    Display *d;
    Window w,w1, w2, w3;
    XEvent e;
    int s;
    XGCValues gr_values1 , gr_values2, gr_values3;
    XFontStruct *font1, *font2, *font3;
    GC gr_context1, gr_context2, gr_context3;
    XColor color, dummy;

    d=XOpenDisplay(NULL);
    if (d == NULL) {
        fprintf(stderr,"cant't open the display");
        exit(1);
    }
    s=DefaultScreen(d);

    w=XCreateSimpleWindow(d,RootWindow(d,s),0,0,DisplayWidth(d,s),DisplayHeight(d,s),2,BlackPixel(d,s),WhitePixel(d,s));
    w1=XCreateSimpleWindow(d,w,200,200,200,100,2,BlackPixel(d,s),WhitePixel(d,s));
    w2=XCreateSimpleWindow(d,w,400,200,200,100,2,BlackPixel(d,s),WhitePixel(d,s));
    w3=XCreateSimpleWindow(d,w,600,200,200,100,2,BlackPixel(d,s),WhitePixel(d,s));

    font1 = XLoadQueryFont(d, "-adobe-new century schoolbook-bold-r-normal--24-240-75-75-p-149-iso8859-9");
    font2 = XLoadQueryFont(d, "-adobe-new century schoolbook-bold-r-normal--18-180-75-75-p-113-iso8859-9");
    font3 = XLoadQueryFont(d, "-adobe-new century schoolbook-bold-r-normal--12-120-75-75-p-77-iso8859-9");
    XAllocNamedColor(d, DefaultColormap(d, s),"purple",&color,&dummy);

    gr_values1.font = font1->fid;
    gr_values1.foreground = color.pixel;
    gr_context1=XCreateGC(d,w,GCFont+GCForeground, &gr_values1);
    gr_values2.font = font2->fid;
    gr_values2.foreground = color.pixel;
    gr_context2=XCreateGC(d,w,GCFont+GCForeground, &gr_values2);
    gr_values3.font = font3->fid;
    gr_values3.foreground = color.pixel;
    gr_context3=XCreateGC(d,w,GCFont+GCForeground, &gr_values3);

    XSetFont(d,gr_context1,font1->fid);
    XSetFont(d,gr_context2,font2->fid);
    XSetFont(d,gr_context3,font3->fid);

    XSelectInput(d,w,ExposureMask);
    XSelectInput(d,w1,KeyPressMask);
    XSelectInput(d,w2,KeyPressMask);
    XSelectInput(d,w3,KeyPressMask);

    XMapWindow(d,w);

    while(1){
        XNextEvent(d, &e);
        if (e.xany.window == w) {
            if (e.type == Expose) {
                 XMapWindow(d,w1);
                 XMapWindow(d,w2);
                 XMapWindow(d,w3);
            }
        }
        if (e.xany.window == w1) {
            if (e.type == KeyPress) {
                XDrawString(d,w1,gr_context1,50,50,"hello",5);
                XDrawString(d,w2,gr_context2,50,50,"hello",5);
                XDrawString(d,w3,gr_context3,50,50,"hello",5);
            }
        }
    }
    XCloseDisplay(d);
    return 0;
}

output of above code

These sizes are not enough for my application. For example, I need size-96 (while selecting in LibreOffice Writer) this is the font selected in LibreOffice Writer, this is size-96. I want like this

Also suggest for loading TrueType fonts
