# kFxPropertyKey_NeedsFullBuffer

A key that determines whether the plug-in needs the entire image to do its processing, and can’t tile its rendering.

```
var kFxPropertyKey_NeedsFullBuffer: String { get }
```

## Discussion

This value of this key is a Boolean `NSNumber` indicating whether this plug-in needs the entire image to do its processing. Note that setting this value to `YES` incurs a significant performance penalty and makes your plug-in unable to render large input images. The default value is `NO`.
