CCTexturePVR Class Reference

Inherits from	NSObject
Declared in	CCTexturePVR.h

Overview

CCTexturePVR

Object that loads PVR images.

Supported PVR formats:

- RGBA8888
- BGRA8888
- RGBA4444
- RGBA5551
- RGB565
- A8
- I8
- AI88
- PVRTC 4BPP
- PVRTC 2BPP

Limitations:

Pre-generated mipmaps, such as PVR textures with mipmap levels embedded in file,
are only supported if all individual sprites are of _square_ size.
To use mipmaps with non-square textures, instead call CCTexture2D#generateMipmap on the sheet texture itself
(and to save space, save the PVR sprite sheet without mip maps included).
