How to display text with different resolutions?

#include <acknex.h>
#include <default.c>
#include <atypes.h>
#include <d3d9.h>
#include <litec.h>

// Call this, if your font is not default Window Font like Arial...
void AddFontType(STRING* name)
{
 	int res = AddFontResource(name);
   if(!res)
        printf("Font %s not found....", name);
}

// ...in Main function
AddFontType("XerosTheorem.ttf");

// Declare your Fonts
FONT* FontMenuMain = "Xero's Theorem#36";
FONT* FontMenuSub = "Xero's Theorem#28";


// Call this after switched Resolution
// MnuSettings.Resolution is an integer in a struct (7,8,9...)
// Override Fonts 
void CreateFont()
{
	// Fonts für den Auflösungswechsel neu erstellen
	
	switch(MnuSettings.Resolution)
	{
		case 1:
		case 2:
			FontMenuMain = font_create("Xero's Theorem#29");
			FontMenuSub = font_create("Xero's Theorem#23");	
			break;
		
		case 3:
			FontMenuMain = font_create("Xero's Theorem#36");
			FontMenuSub = font_create("Xero's Theorem#28");			
			break;
	}	
}


// Use it at runtime like this...
pan_setdigits(MnuPMainScreen, mainDigNum[0], mainDigPosXY[0][0],mainDigPosXY[0][1],StrBtnMnuMission, FontMenuMain,1,0);
