The concept of PDF Layers came with the introduction of PDF.

What is pdf with text layer. A text layer is added to the image layer usually placed underneath. A general-purpose PDF text-layer redaction tool in pure Python by Joshua Tauberer and Antoine McGrath. If by page 3 of the text you mean page 3 of the book what is the problem as I cant see it.

Items on locked layers cannot be hidden. Whilst this action is limited to extracting text from PDF documents simply convert files to PDF format using the Convert to PDF flow action prior to executing this action to enable text to be extracted from 70 different files types. Amazon Textract detects and analyzes text input documents and returns information about detected items such as pages words lines form data key-value pairs tables and selection elements.

To generate a searchable PDF use Amazon Textract to extract text from documents and add the extracted text as a layer to the image in the PDF document. Text in searchable PDF documents can be selected copied and marked up. You can also view the layer properties as they were designed by the author of the document.

The layers are called optional content from a PDF perspective and iText is aware of them and handles them correctly but it doesnt seem to have any public properties stating this is the current layer. When you convert a Word document to a PDF the content written by the original author forms the content layer. Other layers may be in groups with no parent layer.

Its uses include PDF overlays having alternate languages appear and adding details to diagrams. Such PDF files are almost indistinguishable from the original documents and are fully searchable.
