pixelType

Returns the pixel data type.

@property (nonatomic, readonly) GLenum pixelType

size

The size of this texture in pixels.

@property (nonatomic, readonly) CC3IntSize size

Declared In

CC3PVRTexture.h

textureID

The texture ID used to identify this texture to the GL engine.

@property (nonatomic, readonly) GLuint textureID

Instance Methods

initFromFile:

Initializes this instance by loaded content from the specified PVR file.

- (id)initFromFile:(NSString *)filePath

Discussion

The specified file path may be either an absolute path, or a path relative to the application resource directory. If the file is located directly in the application resources directory, the specified file path can simply be the name of the file.

Returns nil if the file could not be loaded.
