I have an OpenGL based app on Mac OSX 10.6.x and I want to compress raw pixel data which I read from the FBO using PVRTC. Is there is PVRTC library with functions like pvrtc\_compress or pvr\_compress etc which I can use from my OSX based app?  
  
  
  
  
  
Appreciate any pointers. Thanks in advance.

Hi ashish\_lal,

&nbsp;
  

Within our SDK packages there is a PVRTC compressor library which should have what you are looking for. This contains documentation instructing you on its use. This is only our high quality compression though, so if you'd like to use our fast compression instead, then you'll want to use the compression within our separate PVRTexLib utility&nbsp;instead.
  

&nbsp;
  

Hope that helps,
