Convert Bitmap objects

Convert a view to a bitmap object

1  Public StaticBitmap getviewbitmap (view view) {2View.measure (View.MeasureSpec.makeMeasureSpec (0, View.MeasureSpec.UNSPECIFIED),3View.MeasureSpec.makeMeasureSpec (0, View.MeasureSpec.UNSPECIFIED));4View.layout (0, 0, View.getmeasuredwidth (), View.getmeasuredheight ());5 View.builddrawingcache ();6Bitmap Bitmap =View.getdrawingcache ();7         returnbitmap;8}

Create a new bitmap based on the existing drawable:

1 PrivateBitmap Bitmap;2 Private voidDrawabletobitamp (drawable drawable)3     {4         intW =drawable.getintrinsicwidth ();5         inth =drawable.getintrinsicheight ();6System.out.println ("Drawable turn Bitmap");7Bitmap.config Config =8Drawable.getopacity ()! = Pixelformat.opaque?Bitmap.Config.ARGB_88889 : Bitmap.Config.RGB_565;TenBitmap =Bitmap.createbitmap (w,h,config); One         //Note that the following three lines of code to use, no in view or Surfaceview in the Canvas.drawbitmap will not see the diagram ACanvas Canvas =NewCanvas (bitmap);  -Drawable.setbounds (0, 0, W, h);  - Drawable.draw (canvas); the}

Remove the bitmap directly from the existing drawable:

1 Private Bitmap Bitmap; 2 3 Private void Drawabletobitamp (drawable drawable) 4     {5         bitmapdrawable bd = (bitmapdrawable) drawable; 6         Bitmap = bd.getbitmap (); 7     }

Bitmap to Byte

1 Private byte [] bitmap2bytes (Bitmap BM) {23     New Bytearrayoutputstream (); 4 5     Bm.compress (Bitmap.CompressFormat.PNG,BAOs); 6 7     return Baos.tobytearray ();   8  }

Byte[] Turn bitmap:

1 PrivateBitmap Bytes2bimap (byte[] b) {2 3                     if(b.length!=0){4 5                             returnBitmapfactory.decodebytearray (b, 0, b.length);6 7                     }8 9                     Else {Ten  One                             return NULL; A  -                     } -  the}
