Instance Attribute Details
- (Object) getBytePointer
A pointer to a function that returns a pointer to the provider’s data. For more information, see CGDataProviderGetBytePointerCallback.
- (Object) getBytes
A pointer to a function that copies data from the provider. For more information, see CGDataProviderGetBytesAtOffsetCallback.
- (Object) releaseBytePointer
A pointer to a function that Quartz calls to release a pointer to the provider’s data. For more information, see CGDataProviderReleaseBytePointerCallback.
- (Object) releaseProvider
A pointer to a function that handles clean-up for the data provider, or NULL. For more information, see CGDataProviderReleaseInfoCallback.
