带摄像头的图像叠加在android系统捕捉到的图像 [英] Image overlay with camera captured image in android

问题描述

我需要拍照与相机，并在同一时间上显示的摄像机视图的顶部叠加图像。拍摄照片后，我需要保存用户所看到的，而拍照。任何人都可以给我建议？请。

解决方案

 公共无效onPictureTaken（字节[]数据，相机摄像头）{
  位图cameraBitmap = BitmapFactory.de codeByteArray的（数据，0，data.length）;  WID = cameraBitmap.getWidth（）;
  HGT = cameraBitmap.getHeight（）;
 位图newImage = Bitmap.createBitmap（WID，HGT，Bitmap.Config.ARGB_8888）;  帆布帆布=新的Canvas（newImage）;  canvas.drawBitmap（cameraBitmap，0F，0F，NULL）;  可绘制可绘制= getResources（）getDrawable（R.drawable.d）。
  drawable.setBounds（20，20，260，160）;
  drawable.draw（画布）;  文件storagePath =新的文件（Environment.getExternalStorageDirectory（）+/吸血鬼图片/）;
  storagePath.mkdirs（）;  文件MYIMAGE =新的文件（storagePath，Long.toString（System.currentTimeMillis的（））+.JPG）;  尝试
  {
    FileOutputStream中出=新的FileOutputStream（MYIMAGE）;
    newImage.com preSS（Bitmap.Com pressFormat.JPEG，90出）;
    了out.flush（）;
    out.close（）;
  }
  赶上（FileNotFoundException异常E）
  {
   Log.d（在保存文件E +）;
  }
  赶上（IOException异常E）
  {
    Log.d（在保存文件E +）;
  }  camera.start preVIEW（）;  可绘制= NULL;  newImage.recycle（）;
  newImage = NULL;  cameraBitmap.recycle（）;
  cameraBitmap = NULL;
 }};
 

I need to take a picture with the camera and at the same time show an overlay image on top of the camera view. After the picture is taken, i need to save what the user saw while taking the picture. Can anyone suggest me? Please.

解决方案

  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;
 } };
