Description

Display a label the way you're used to, and add the modifiers you need. You can draw a label with a specific size, color, font, color or alignement (feel free to add new ones), any changes are reversed after the label is drawn. This is a much simpler but less powerfull alternative to fancy labels (http://forum.unity3d.com/threads/9549-FancyLabel-Multicolor-and-Multifont-label/)

Usage

Just use the static class AdvancedLabel as you would use GUI or GUILayout. The functions are Draw and DrawLayout.

Here is an example :

C# 

GUILayout.BeginArea( rect );
    AdvancedLabel.DrawLayout( "Big size", new GUILayoutOption[]{ GUILayout.MinHeight(20) }, new NewFontSize(20), new NewColor(Color.yellow) );
    AdvancedLabel.DrawLayout( "Small size", new NewFontSize(12) );
GUILayout.EndArea();

JS 

#pragma strict
var skin : GUISkin;
 
function OnGUI()
{
	GUI.skin = skin;
	GUILayout.BeginArea( Rect( 0, 0, Screen.width, Screen.height ) );
		AdvancedLabel.DrawLayout( "TITLE", (new Array( NewFontSize(50), NewColor(Color.yellow) ).ToBuiltin(ILabelParameter)) as ILabelParameter[] );
		AdvancedLabel.DrawLayout( "Subtitle", (new Array( NewFontSize(30), NewFontStyle(FontStyle.Bold) ).ToBuiltin(ILabelParameter)) as ILabelParameter[] );
		GUILayout.Label( "Normal" );
		AdvancedLabel.DrawLayout( "Middle Center", (new Array( NewAlignement(TextAnchor.MiddleCenter) ).ToBuiltin(ILabelParameter)) as ILabelParameter[] );
		GUILayout.FlexibleSpace();
	GUILayout.EndArea();
}
