title: On the fly PVRTC compression on iOS
body: <p>I'm writing an iPhone app that is quite heavy on GPU memory. Some of the textures are created procedurally by the app, which means that I cannot compress them to PVRTC to decrease their on-GPU size (and thus memory).
  Does anyone know of a library that does this?
  The closest I found was PVRTexLib ( <a href="http://www.imgtec.com/powervr/insider/powervr-pvrtexlib.asp" rel="nofollow noreferrer">http://www.imgtec.com/powervr/insider/powervr-pvrtexlib.asp</a> ) but that is for MacOSX, and not iOS.</p>
  
  <p>I found this question which is similar : <a href="https://stackoverflow.com/questions/1020944/convert-png-to-pvrtc-on-the-iphone">Convert .png to PVRTC *on* the iPhone</a> but they took it to a different direction (on why you shouldn't want to do it).
  However, my app uses OpenGL so I do benefit greatly from being able to use PVRTC.</p>
  
  <p>Does anyone know of such a library?</p>
