# kvImageGetTempBufferSize

A flag that returns the minimum temporary buffer size for the operation, given the parameters provided.

## Declaration

```swift
var kvImageGetTempBufferSize: Int { get }
```

## Mentioned in

Applying geometric transforms to images

## Discussion

Discussion When you set this flag, the function returns the number of bytes required for the temporary buffer instead of performing the operation. A negative value indicates an error, and if the function does not accept a temporary buffer, zero is returned.
