用相机拍摄的图像叠加在android中拍摄的图像
答
public void onPictureTaken(byte[] data, Camera camera){
Bitmap cameraBitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
wid = cameraBitmap.getWidth();
hgt = cameraBitmap.getHeight();
Bitmap newImage = Bitmap.createBitmap(wid , hgt , Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(newImage);
canvas.drawBitmap(cameraBitmap, 0f, 0f, null);
Drawable drawable = getResources().getDrawable(R.drawable.d);
drawable.setBounds(20 ,20, 260, 160);
drawable.draw(canvas);
File storagePath = new File(Environment.getExternalStorageDirectory() + "/Vampire Photos/");
storagePath.mkdirs();
File myImage = new File(storagePath,Long.toString(System.currentTimeMillis()) + ".jpg");
try
{
FileOutputStream out = new FileOutputStream(myImage);
newImage.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
}
catch(FileNotFoundException e)
{
Log.d("In Saving File", e + "");
}
catch(IOException e)
{
Log.d("In Saving File", e + "");
}
camera.startPreview();
drawable = null;
newImage.recycle();
newImage = null;
cameraBitmap.recycle();
cameraBitmap = null;
} };
你有没有想过这个?我需要这样做。已经让相机与覆盖层一起工作,但我无法将两者保存为一个图像。 –
