Syntax

function ReadablePageContent(PageNumber: Integer): TPdfReadableContent;

Parameters

PageNumber

Integer. One-based document page number

Return Value

TPdfReadableContent. Semantic readable fragments for the requested page

Description

Readable content is built from the page structure tree when the document is tagged and falls back to page text order when it is not. Each fragment carries text, kind, language, page number, bounding rectangle, line rectangles, and source information

Use the page-level members for current-page workflows and DocumentReadableContent when a speech or export pipeline needs a single ordered list for the whole document

Remarks

API names, type names, and PDF terms keep their original spelling so code search remains reliable
Call the member only after the owning document or viewer is active unless the syntax describes an event or design-time property

Example

var Content: TPdfReadableContent;
Content := Pdf1.ReadableContent;
if Length(Content.Fragments) > 0 then
ShowMessage(Content.Fragments[0].Text);
