OCR.Recognize Method

Applies to TestComplete 14.71, last modified on April 22, 2021

Description

The OCR.Recognize method recognizes the text of the specified UI element or image and returns an OCRTextDocument object that provides access to all the recognized text and individual text blocks and tabular data.

Requirements
  • Your TestComplete version must be 12.60 or later.

  • You need an active license for the TestComplete Intelligent Quality add-on.

  • The Intelligent Quality add-on must be enabled in TestComplete.

    You can enable the add-on during TestComplete installation. If you did not enable the add-on during the installation, you can do this at any moment later via the File > Install Extensions dialog. To do that, select File > Install Extensions from the TestComplete main menu and enable the Intelligent Quality > Intelligent Quality Core plugin in the resulting dialog.

  • Optical Character Recognition support must be enabled in TestComplete.

    By default, it is enabled automatically if you enable the Intelligent Quality add-on during TestComplete installation. If you experience issues with optical character recognition in your tests, select File > Install Extensions from the TestComplete main menu and make sure the Optical Character Recognition plugin is enabled (you can find it in the Intelligent Quality group). If the plugin is disabled, enable it. In the confirmation message that TestComplete shows when you enable the plugin, click the link to read a third-party license agreement. If you agree to the license terms, click Enable OCR.

    In addition, make sure that you do not have the legacy OCR plugin installed and enabled. You can find the plugin in the Common group.

  • Your computer must have access to the ocr.api.dev.smartbear.com web service. If you have firewalls or proxies running in your network, they should allow your computer to access the web service.

  • Your firewall must allow traffic through port 443.

function GetRecognizedText()
{
  var p = Sys.WaitProcess("notepad", 3000);
  if (p.Exists)
  {
    // Get the Notepad window

      // Get the About Notepad window
      var wndAbout = p.WaitWindow("#32770", "About Notepad", 1, 3000);
      if (wndAbout.Exists)
      {
        // Recognize the text that the About Notepad window contains
        var recognizedText = OCR.Recognize(wndAbout);

        // Post the recognized text to the test log
        Log.Message("View all the recognized text in the Details panel", recognizedText.FullText);

        // Post portions of the recognized text to the test log
        if (recognizedText.BlockCount > 0)
        {
          Log.AppendFolder("Recognized text by blocks");
          for (var i = 0; i < recognizedText.BlockCount; i++)
          {
            Log.Message(recognizedText.Block(i).Text);
          }
          Log.PopLogFolder();
        }
