Class PixelData

Definition

Namespace:: Tizen.NUI

Assembly:: Tizen.NUI.dll

API Level:: 5

The PixelData object holds a pixel buffer.
The PixelData takes over the ownership of the pixel buffer.
The buffer memory must not be released outside of this class, instead, the PixelData object will release it automatically when the reference count falls to zero.
