API & integration Details

Available properties and method

SDK has four core classes and supporting classes :

CameraHelper - Handles the camera related operations. Basically, an activity.
ImgHelper - Purpose of this class is to handle all imaging related operations.
OpticalCodeHelper - Handles the Optical code (QR CODE & BAR CODE) related activities
HumanFaceHelper - Advanced Ai based utility class handles all functionalities such as face detection, extraction,matching & related functions.
Config - Holds various configurations for SDK including licensing

Based on the requirement, any one or all classes can be used.And need to import those from the SDK.

    import com.extrieve.quickcapture.sdk.*;
    //OR : can import only required classes as per use cases.
    import  com.extrieve.quickcapture.sdk.ImgHelper;  
    import  com.extrieve.quickcapture.sdk.CameraHelper;
    import  com.extrieve.quickcapture.sdk.OpticalCodeHelper;
    import  com.extrieve.quickcapture.sdk.Config;  
    import com.extrieve.quickcapture.sdk.HumanFaceHelper;
    import  com.extrieve.quickcapture.sdk.ImgException;

1. CameraHelper

This core class will be implemented as an activity.This class can be initialized as intent.

//JAVA
CameraHelper CameraHelper = new CameraHelper();

//Kotlin
var cameraHelper: CameraHelper? = CameraHelper()

With an activity call, triggering the SDK for capture activity can be done.Most operations in CameraHelper is activity based.

SDK is having multiple flows as follows :

CAMERA_CAPTURE_REVIEW - Default flow. Capture with SDK Camera -> review.
SYSTEM_CAMERA_CAPTURE_REVIEW - Capture with system default camera -> review.
IMAGE_ATTACH_REVIEW - Attach/pass image -> review.

1. CAMERA_CAPTURE_REVIEW - Default flow of the CameraHelper. Includes Capture with SDK Camera -> Review Image.

//JAVA

//Set CaptureMode as CAMERA_CAPTURE_REVIEW
Config.CaptureSupport.CaptureMode = Config.CaptureSupport.CaptureModes.CAMERA_CAPTURE_REVIEW;
//set permission for output path that set in config.
UriphotoURI = Uri.parse(Config.CaptureSupport.OutputPath);
this.grantUriPermission(this.getPackageName(),photoURI,Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);  

//Create CameraIntent for CameraHelper activity call.
Intent CameraIntent = new Intent(this,Class.forName("com.extrieve.quickcapture.sdk.CameraHelper"));
if  (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP)  {
	CameraIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
}
//Call the Activity.
startActivityForResult(CameraIntent,REQUEST_CODE_FILE_RETURN);

//On activity result,recieve the captured, reviewed, cropped, optimised & compressed image collection as array.
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data)  
{
	super.onActivityResult(requestCode,  resultCode,  data);
	if  (requestCode == REQUEST_CODE_FILE_RETURN && resultCode == Activity.RESULT_OK)
	{  
		Boolean Status = (Boolean)data.getExtras().get("STATUS");
		String Description = (String)data.getExtras().get("DESCRIPTION");  
		if(Status == false){ 
			//Failed  to  capture
		}
		finishActivity(REQUEST_CODE_FILE_RETURN); return;
	}
	FileCollection = (ArrayList<String>)data.getExtras().get("fileCollection");
	//FileCollection //: will contain all capture images path as string
	finishActivity(REQUEST_CODE_FILE_RETURN);
}

//Kotlin
try {
    /*DEV_HELP :redirecting to camera*/
    val captureIntent = Intent(this, Class.forName("com.extrieve.quickcapture.sdk.CameraHelper"))
    val photoURI = Uri.parse(Config.CaptureSupport.OutputPath)
    grantUriPermission(
	this.packageName, photoURI,
	Intent.FLAG_GRANT_WRITE_URI_PERMISSION or Intent.FLAG_GRANT_READ_URI_PERMISSION
    )
    if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP) {
	captureIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
    }
    captureActivityResultLauncher!!.launch(captureIntent)
} catch (ex: Exception) {
    /*DEV_HELP : TODO : handle invalid Exception*/
    Toast.makeText(this, "Failed to open camera  -" + ex.message, Toast.LENGTH_LONG).show()
}

2. SYSTEM_CAMERA_CAPTURE_REVIEW - If user needs to capture an image with system default camera, this can be used. It includes Capture with system default camera -> Review.

//JAVA

}
//Call the Activity.
startActivityForResult(CameraIntent,REQUEST_CODE_FILE_RETURN);

//On activity result,recieve the captured, reviewed, cropped, optimised & compressed image colletion as array.
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data)  
{
	super.onActivityResult(requestCode,  resultCode,  data);
	if  (requestCode == REQUEST_CODE_FILE_RETURN && resultCode == Activity.RESULT_OK)
	{

try {
    /*DEV_HELP :redirecting to camera*/
    val captureIntent = Intent(this, Class.forName("com.extrieve.quickcapture.sdk.CameraHelper"))
    val photoURI = Uri.parse(Config.CaptureSupport.OutputPath)
    grantUriPermission(
	this.packageName, photoURI,
	Intent.FLAG_GRANT_WRITE_URI_PERMISSION or Intent.FLAG_GRANT_READ_URI_PERMISSION
    )
    if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP) {
	captureIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
    }
    captureActivityResultLauncher!!.launch(captureIntent)
} catch (ex: Exception) {

CaptureSupport - Contains all the Capture & review related configurations. Config.CaptureSupport contains various configurations as follows:

BottomStampData - This configuration will automatically print the specified text at the bottom of the captured image with correct alignment, font size and DPI**. This also supports placeholders, such as {DATETIME}, which will be replaced with the current date and time from the device at the time of stamping. $ - for new line print.
```
  //JAVA
 Config.CaptureSupport.BottomStampData ="{DATETIME} , Other info $ next line info.";
```
```
  //Kotlin
 Config!!.CaptureSupport!!.BottomStampData = ="{DATETIME} , Other info $ next line info.";
```
