Detailed Description


Object that loads PVR images.

Supported PVR formats:

  • RGBA8888
  • BGRA8888
  • RGBA4444
  • RGBA5551
  • RGB565
  • A8
  • I8
  • AI88

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 generateMipmap (CCTexture2D) on the sheet texture itself (and to save space, save the PVR sprite sheet without mip maps included).
