OCR (Optical Character Recognition) is a technology that enables the conversion of document types such as scanned paper documents, PDF files or pictures taken with a digital camera into editable and searchable data. OCR creates words from letters and sentences from words by selecting and separating letters from images.

With the Read Content OCR action, you can read the texts in the images. This feature is a feature generally used by Documentation Management companies to read and convert the invoices or documents they have issued into text format. With this feature, documents containing keywords from all documents are filtered and the desired documents can be accessed easily.

Read Content (OCR) action features:

Value Area: It is selected to which area the text to be read will be sent.

Remove Lines: There are lines in the picture to be read, and if these lines are to be removed, the Remove Lines feature should be selected as “Yes”. In case of being selected, the text reading speed will slow down as it will check for lines one by one for each line in line-based scanning operations.

OCR Mapping: If you want to read the desired line or the area containing the desired information by mapping on the document, the OCR Mapping field should be used. It transfers only the requested information to the form page, not the entire document. Multiple mapping operations can be performed by pressing the + button. Two different selections can be made from the Type field. Field performs field-based operation and row performs row-based operation. Example usage is included in the document.

When the Read Text button is clicked, the file selection screen opens for the selection of the document to be read and the file to be read is selected from here.

The receipt example we have chosen for this example is as follows.

The better the quality of the receipts drawn or scanned, the better the result will be. The images to be used must have a minimum value of 300DPi.

After selecting the relevant image from the file selection area, all text values ​​in the receipt will be added line by line in the text box.

All texts on a picture were read and sent to the relevant area.

Example Usage 2(OCR Mapping):

If you want to retrieve only the desired row or the row where the requested information is displayed, not all the information on a receipt, the Mapping operation is performed.

For this example, the Invoice No, Invoice Date, Total and Received values ​​on the receipt will be sent to the fields on the relevant form page.
