Detailed Description

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

Property Documentation

- (BOOL) forcePremultipliedAlpha [read, assign]

whether or not the texture should use hasPremultipliedAlpha instead of global default

- (BOOL) hasAlpha [read, assign]

whether or not the texture has alpha
