ReusableBitmap

public class ReusableBitmap extends Object implements Poolable
A simple bitmap wrapper. Currently supports reference counting and logical width/height (which may differ from a bitmap's reported width/height due to bitmap reuse).

Fields Summary
public final android.graphics.Bitmap
bmp
private int
mWidth
private int
mHeight
private int
mOrientation
private int
mRefCount
private final boolean
mReusable
Constructors Summary
public ReusableBitmap(android.graphics.Bitmap bitmap)


        
        this(bitmap, true /* reusable */);
public ReusableBitmap(android.graphics.Bitmap bitmap, boolean reusable)

        bmp = bitmap;
        mReusable = reusable;
