Examples

Set new Region of interest with new Camera orientation

This example can be used to scan BVR in a portrait application (the must be put in landscape).

Display display = getActivity().getWindowManager().getDefaultDisplay();
int stageWidth = display.getWidth();
int stageHeight = display.getHeight();
int width = stageWidth, height = stageHeight;
if(width > height)
    // Set new ROI
    mSmartScanner.setRegionOfInterest(new Rect(height / 100 * 15,width / 10 ,width / 100 * 95,height / 100 * 80));
else {
    /**
     * Set the new orientation decoding on the device. By activating this mode you must manage the ROI manually.
     * @param forceOrientationEnabled true if the decoder should decode in manual orientation
     * @param scanOrientation the orientation for decoding.The options are: LANDSCAPE_MODE, LANDSCAPE_REVERSE_MODE, PORTRAIT_MODE, PORTRAIT_REVERSE_MODE
     *
     */
    mSmartScanner.setOrientationDecoding(true, SmartScanner.LANDSCAPE_MODE);
    mSmartScanner.setRegionOfInterest(new Rect(height / 100 * 10, width / 100 * 15, width / 100 * 85, height / 100 * 90));
}

Flash

Enable/disable the flash with a toggle button

...
someToggleButton.setOnCheckedChangeListener(flashModeLister);
...

private CompoundButton.OnCheckedChangeListener flashModeLister = new CompoundButton.OnCheckedChangeListener(){
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if(isChecked)
            mSmartScanner.setFlashEnabled(true);
        else
            mSmartScanner.setFlashEnabled(false);
    }
};

Enable/disable Auto-Focus

Enable/disable the Auto-Focus with a toggle button

...
someToggleButton.setOnCheckedChangeListener(focusModeLister);
...

private CompoundButton.OnCheckedChangeListener focusModeLister = new CompoundButton.OnCheckedChangeListener(){
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if(isChecked)
            mSmartScanner.setAutoFocusEnabled(true);
        else
            mSmartScanner.setAutoFocusEnabled(false);
    }
};

Manual focus

On main layout put the focus view

<View
    android:id="@+id/focus"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:visibility="gone"
    android:background="@drawable/rectangle" />

Add to drawable folder the new shape

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="#00000000" />

    <stroke
        android:width="1dp"
        android:color="#8BC34A" />

    <padding
        android:bottom="1dp"
        android:left="1dp"
        android:right="1dp"
        android:top="1dp" />

</shape>

/**
* On double tap we switch to manual focus. We try focusing on the region were the double tap was done.
* @param x Position on x axis on the screen
* @param y Position on y axis on the screen
* @param view View where we will draw the focus rectangle
* @param isFocusRectangleVisible Option to draw the focus rectangle or not
*/

mSmartScanner.manualFocus(mPrimStartTouchEventX, mPrimStartTouchEventY, root.findViewById(R.id.focus), true);

Enable disable hight resolution

Enable/disable the resolution with a toggle button

...
someToggleButton.setOnCheckedChangeListener(focusModeLister);
...

private CompoundButton.OnCheckedChangeListener focusModeLister = new CompoundButton.OnCheckedChangeListener(){
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if(isChecked)
            mSmartScanner.setHighResolution(true);
        else
            mSmartScanner.setHighResolution(false);
    }
};

Save picture

Add a view to display the image

<ImageView
    android:id="@+id/picture_view"
    android:layout_width="wrap_content"
    android:layout_height="150dp"
    android:layout_gravity="center"/>
</LinearLayout>

Implement the OnSavedPictureReadyListener listener

mSmartScanner.setOnSavedPictureReadyListener(pictureBytes -> {
    if (pictureBytes != null) {
        Bitmap bmp = BitmapFactory.decodeByteArray(pictureBytes, 0, pictureBytes.length);
        ((ImageView) findViewById(R.id.picture_view)).setImageBitmap(bmp);
    }
});

Trigger a capture with the following function

/**
* Take a picture of the scanning process
* @param onlyROI Set the area of the picture capture
*/
mSmartScanner.savePicture(onlyRoi)

or enable automatic capture when the image is successfully decoded

/**
* If enabled, each successfully decoded image is saved and returned via the OnSavedPictureReadyListener listener
* @param enabled Set the state of the returned image
* @param onlyROI Set the area of the picture capture
*/
mSmartScanner.setOnLoadedListener(roi -> {
    mSmartScanner.setSaveDecodedPictureEnabled(enabled, onlyRoi);
});
