Page Processing

The CPageProcessing class gathers all processing features: Page Analysis, Barcode Detection & Text Recognition in one class.
You can choose which feature to enable or disable.
The order of features execution is as follows:

1. Page Analysis
2. Barcode Detection
3. Text Recognition

Each feature works only on CPage objects and each step can alter the state of the CPage object. By using this class, you can choose the features to use, set the associated parameters and run all the necessary processing on a given page via a single call.

For Page Analysis followed by Text Recognition, you can consult the code snippet below:

Page Analysis followed by Text Recognition

CIDRS objIdrs = CIDRS::Create();

// Load the source image
CImageIO objImageIO = CImageIO::Create(objIdrs);
CPage objPage = objImageIO.LoadPage("path/to/image");

// create page processing object and enable page analysis & text recognition
CPageProcessing objPageProcessing = CPageProcessing::Create(objIdrs);
objPageProcessing.SetRunPageAnalysis(IDRS_TRUE);
objPageProcessing.SetRunTextRecognition(IDRS_TRUE);

// create & set page analysis params
CPageAnalysisParams objPageAnalysisParams = CPageAnalysisParams::Create();
objPageAnalysisParams.SetDetectLanguage(IDRS_TRUE);
objPageAnalysisParams.SetDetectOrientation(IDRS_TRUE);
objPageProcessing.SetPageAnalysisParams(objPageAnalysisParams);

// create & set text recognition params
COcrContext objContext = COcrContext::Create(Language::Japanese);
COcrPageParams objOcrPageParams = COcrPageParams::Create(objContext);
objOcrPageParams.SetThreadingMode(ThreadingMode::Limited);
objPageProcessing.SetOcrParams(objOcrPageParams);

// run page processing
objPageProcessing.ProcessPage(objPage);
