如何从相机预览（表面视图）中裁剪图像并保存它，而不是像instagram app这样捕获bt相机的实际图像？

Question

I have an activity with surface view (match parent-match parent), half of which is hidden by button. Is it possible to save only visible part of captured picture? I've tried to make the surface view smaller, but preview is either rotated in this case or stretched. I'm using android.hardware.camera1 btw

 <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_camera" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="uz.pages.yangiuz10.activity.CameraActivity"> <SurfaceView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/surface_camera"/> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <View android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1"/> <RelativeLayout android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:background="@color/colorBackgroundText"> <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/button_shot" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:src="@drawable/shot_btn" android:background="@null" android:onClick="onPictureCapture"/> </RelativeLayout> </LinearLayout> </RelativeLayout>
