PHP

Step 1:   Install ClearImage SDK
Download and install the ClearImage SDK.﻿
Step 2:   Configure ClearImage
PHP code uses ClearImage.dll through COM API.  ClearImage DLL is registered as a COM object during installation. To register manually, run the following command as Administrator.
regsvr32 "C:\Program Files (x86)\Inlite\ClearImageSDK\register.bat
Add this section to php.ini, if not set yet.
  [PHP_COM_DOTNET]
  extension=php_com_dotnet.dll
  fastcgi.impersonate = 0﻿
Error  'Class ‘COM’ not found'   indicates that the above is not configured.
ClearImage DLL API reports errors as an Exception object. 
PHP
<?php
 try {
   		// Create ClearImage COM Server
    $Server = new COM("ClearImage.ClearImage");
	//  Your PHP code
  }
  catch(Exception $e) {
    print "Exceptiom in line " . $e->getLine() . "\n" . $e->getMessage() . "\n";
  }
 ?>
<?php
 try {
   		// Create ClearImage COM Server
    $Server = new COM("ClearImage.ClearImage");
	//  Your PHP code
  }
  catch(Exception $e) {
    print "Exceptiom in line " . $e->getLine() . "\n" . $e->getMessage() . "\n";
  }
 ?>

ClearImage project development
Extend functionality
While developing your application, you can combine code examples on this page with methods described in  ClearImage API documentation in the ClearImage COM API section.
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->AutoDetect1D=true; automatically finds the barcode type, but it is slower and is not recommended for production.  

PHP
<?php
function ReadBarcode1D_page ($Server, $fileName, $page)
{
	$reader = $Server->CreateBarcodePro();
	$cibfCode39 = 2; $cibfCode128 = 4;
	$reader->Type = $cibfCode39 + $cibfCode128;
	$reader->Image->Open($fileName, $page); 
	$BCcount = $reader->Find(0);
	for ($i=1;$i<=$BCcount;$i++) {
		$Bc = $reader->BarCodes($i);
		print "Text: " . $Bc->Text . "\n";
		}
}
?>
<?php
function ReadBarcode1D_page ($Server, $fileName, $page)
{
	$reader = $Server->CreateBarcodePro();
	$cibfCode39 = 2; $cibfCode128 = 4;
	$reader->Type = $cibfCode39 + $cibfCode128;
	$reader->Image->Open($fileName, $page); 
	$BCcount = $reader->Find(0);
	for ($i=1;$i<=$BCcount;$i++) {
		$Bc = $reader->BarCodes($i);
		print "Text: " . $Bc->Text . "\n";
		}
}
?>

Read 2D Barcode from a page
This example reads PDF417, DataMatrix, and QR code.   
PHP
<?php
function ReadBarcode2D_page ($Server, $fileName, $page)
{
	$reader = $Server->CreateQR();
	// $reader = $Server->CreatePdf417();
	// $reader = $Server->CreateDataMatrix();
	$reader->Image->Open($fileName, $page); 
	$BCcount = $reader->Find(0);
	for ($i=1;$i<=$BCcount;$i++) {
		$Bc = $reader->BarCodes($i);
		print "Text: " . $Bc->Text . "\n";
		}
}
?>
<?php
function ReadBarcode2D_page ($Server, $fileName, $page)
{
	$reader = $Server->CreateQR();
	// $reader = $Server->CreatePdf417();
	// $reader = $Server->CreateDataMatrix();
	$reader->Image->Open($fileName, $page); 
	$BCcount = $reader->Find(0);
	for ($i=1;$i<=$BCcount;$i++) {
		$Bc = $reader->BarCodes($i);
		print "Text: " . $Bc->Text . "\n";
		}
}
?>
﻿
2D barcodes might contain binary data in  $Bc->Data property as an integer array.  To access all elements:
foreach ($Bc->Data as $val) {print "   " .  $val;}
Read Postal Barcodes from a page
This example reads Postal Barcodes from an image file page.   
PHP

{
	$reader = $Server->CreateBarcodePro();
    $cibf4State = 0x2000000;
	$reader->Type = $cibf4State;
	$reader->Image->Open($fileName, $page); 
	$BCcount = $reader->Find(0);
	for ($i=1;$i<=$BCcount;$i++) {
		$Bc = $reader->BarCodes($i);
        $type1 =$Bc->Type;
        if ($type1 == 33) echo " US Intelligent Mail "; // cibUspsIntelligentMail = 33
        if ($type1 == 34) echo "UK Royal Mail "; // cibBpoPostcode = 34
        if ($type1 == 35) echo "Australian Mail "; // cibAustralianPost = 35 
        if ($type1 == 37) echo "Singapore Mail "; // cibSingaporePost = 37
		print "  Text: " . $Bc->Text . "\n";
		}
}
?>
<?php
function ReadBarcodePostal_page ($Server, $fileName, $page)
{
	$reader = $Server->CreateBarcodePro();
    $cibf4State = 0x2000000;
	$reader->Type = $cibf4State;
	$reader->Image->Open($fileName, $page); 
	$BCcount = $reader->Find(0);
	for ($i=1;$i<=$BCcount;$i++) {
		$Bc = $reader->BarCodes($i);
        $type1 =$Bc->Type;
        if ($type1 == 33) echo " US Intelligent Mail "; // cibUspsIntelligentMail = 33
        if ($type1 == 34) echo "UK Royal Mail "; // cibBpoPostcode = 34
        if ($type1 == 35) echo "Australian Mail "; // cibAustralianPost = 35 
        if ($type1 == 37) echo "Singapore Mail "; // cibSingaporePost = 37
		print "  Text: " . $Bc->Text . "\n";

Image Processing
Repair image page
This example uses some of the most popular image-processing functions. In a production application, the specific sequence of functions should be selected based on specific application needs. 
PHP

	$repair->AutoCrop(10, 10, 10, 10);   // Crop to 10 pixels on each side to bitonal
	$repair->AdvancedBinarize(0, 0 , 0);        // Convert to bitonal an image with complex background patterns
	$ciBexBorderDeskewCrop = 3;
	$ciBeaCleaner = 2;
	$repair->BorderExtract($ciBexBorderDeskewCrop, $ciBeaCleaner); // Deskew and crop based on black border
	$repair->RemovePunchHoles();
	$ciSmoothDarkenEdges = 1;
