Java

Step 1:   Install ClearImage SDK
Download and install the ClearImage SDK.  
Step 2:   Configure your project
Add ClearImageJ.jar to CLASSPATH. Typically file is located in C:\Program Files (x86)\Inlite\Libs folder.
Java API uses several methods to locate ClearImage.dll listed below in descending priority.
Explicit path using the CiServer.loadClearImage(ClearImageDllPath) method.
Folder specified by -Djava.library.path="ClearImageDllPath" on the java command line.
Folders specified by the PATH environmental variable
Use the correct  32-bit or 64-bit version of  ClearImage.dll, that matches your Java runtime version.    ClearImage.dll is located in subfolder of   C:\Program Files (x86)\Inlite\ClearImageSDK folder  \win32  and  \x64 
This code demonstrates the use of ClearImage Java API.  Runtime errors are reported in Exception object.
Java
 ICiServer initClearImage() {
	 try {
		CiServer.loadClearImage("C:\\Program Files (x86)\\Inlite\\ClearImageSDK\\x64\\ClearImage.dll");

		 ICiServer Server = onjServer.getICiServer();
		 return Server;
	 } catch (Exception ex) {
		 System.out.println(ex.getMessage());
		 return null;

ClearImage project development
Extend functionality
While developing your application, you can combine code examples on this page with methods described in ClearImage API documentation .
Exception handling
ClearImage Java API reports errors as an Exception object. 
C#
try {
    //  Call ClearImage .NET API
    } catch (Exception ex)	{
		System.out.println(ex.getMessage());
	}
try {
    //  Call ClearImage .NET API
    } catch (Exception ex)	{
		System.out.println(ex.getMessage());

Barcode Reading
Read 1D  barcodes from a page
This example reads code 39 and code 128 barcodes.   Set barcode types used in your application. Setting reader.setAutoDetect1D(EBoolean.ciTrue); automatically finds the barcode type, but it is slower and is not recommended for production.  

Java
void ReadBarcode1D_page(ICiServer Server, String fileName, int page) {
	try {
		ICiBarcodePro reader = Server.CreateBarcodePro();
		reader.setType(new FBarcodeType(FBarcodeType.cibfCode39,
				FBarcodeType.cibfCode128)); 
		// readerbcr.setAutoDetect1D(EBoolean.ciTrue);
		reader.getImage().Open(fileName, page);
		reader.Find(0);
		for (int i = 1; i <= reader.getBarcodes().getCount(); i++) {
			ICiBarcode Bc = reader.getBarcodes().getItem(i);
			System.out.println(Bc.getText()); 
		}
	} catch (Exception ex) {
		System.out.println(ex.getMessage());
	} finally {
		System.gc();
	}
}
void ReadBarcode1D_page(ICiServer Server, String fileName, int page) {
	try {
		ICiBarcodePro reader = Server.CreateBarcodePro();
		reader.setType(new FBarcodeType(FBarcodeType.cibfCode39,
				FBarcodeType.cibfCode128)); 
		// readerbcr.setAutoDetect1D(EBoolean.ciTrue);
		reader.getImage().Open(fileName, page);
		reader.Find(0);
		for (int i = 1; i <= reader.getBarcodes().getCount(); i++) {
			ICiBarcode Bc = reader.getBarcodes().getItem(i);
			System.out.println(Bc.getText()); 
		}
	} catch (Exception ex) {
		System.out.println(ex.getMessage());
	} finally {
		System.gc();
	}

Read 2D Barcode from a page
This example reads PDF417, DataMatrix, and QR code. 2D barcodes might contain binary data available from Bc.getData() as byte[]﻿

		reader.getImage().Open(fileName, page);
		reader.Find(0);
		for (int i = 1; i <= reader.getBarcodes().getCount(); i++) {
			ICiBarcode Bc = reader.getBarcodes().getItem(i);
			System.out.println(Bc.getText()); 
		}
	} catch (Exception ex) {
		System.out.println(ex.getMessage());
	} finally {
