[操作系统]图片分割


首先建立一个小块图片的类,保存切割后的图片

public class ImagePiece {	private int index;	private Bitmap bitmap;	public ImagePiece()	{}	public ImagePiece(int index,Bitmap bitmap) {		this.index=index;		this.bitmap=bitmap;	}		public int getIndex() {		return index;	}		public void setIndex(int index) {		this.index = index;	}		public Bitmap getBitmap() {		return bitmap;	}		public void setBitmap(Bitmap bitmap) {		this.bitmap = bitmap;	}		@Override	public String toString() {		return "ImagePiece [index=" + index + ", bitmap=" + bitmap				+ ", toString()=" + super.toString() + "]";	}}

  切割图片

/**	 * 传入一个bitmap 	 * @param bitmap	 * @param piece	 * @return List<ImagePiece>	 */	public static List<ImagePiece> splitImage(Bitmap bitmap,int piece)	{				List<ImagePiece> imagePieces=new ArrayList<ImagePiece>();						int width=bitmap.getWidth();		int height=bitmap.getHeight();				int pieceWidth=Math.min(width, height)/piece;						for(int i=0;i<piece;i++)		{			for(int j=0;j<piece;j++)			{				ImagePiece imagePiece=new ImagePiece();				imagePiece.setIndex(j+i*piece);								int x=j*pieceWidth;				int y=i*pieceWidth;				Log.i("x", x+"");				Log.i("y", y+"");				imagePiece.setBitmap(Bitmap.createBitmap(bitmap, x, y, pieceWidth, pieceWidth));								imagePieces.add(imagePiece);							}		}		return imagePieces;	}
