To add only a text layer to a document and exclude the preprocessing of its image, recognize a document in the PDF-Editor and save it as described below:
- On the New Task screen, click the Open tab > click Open PDF Document > select your document;
- In the PDF-Editor click the Recognize button on the toolbar > Recognize Document... or press Ctrl+Shift+R;
- Specify the OCR-languages of your document;
If needed, here you can also enable some options of image preprocessing, such as Correct page orientation and Deskew images and correct image resolution.
- Click Recognize button;
- After a text layer has been added, save the document by clicking button or Save As > PDF Document (Ctrl+Schift+S):
To the file name of the saved document _recognized will be added. And you will get a searchable PDF, in which you can search, select, and copy text.
