JavaScript Requires Chilkat v11.7.0+
JavaScript
Code Blocks and Code Spans in PDF to Markdown
See more PDF Text Extraction Examples
Demonstrates how monospaced text is converted by the "markdown" operation: a monospaced block becomes a fenced code block and a monospaced run inside a sentence becomes a code span. Set "code" to false to treat it as ordinary text.
Note
This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat
v11.4.0 or greater.

// # Extracting Text

// Load the PDF and call `ExtractText` with the operation and an options object. The result is returned as JSON:
//
// ```
// new Pdf pdf;
// success = pdf.LoadFile("report.pdf");
// new JsonObject json;
// new JsonObject jsonOut;
// success = pdf.ExtractText("text",json,jsonOut);
// println jsonOut.StringOf("text");
// ```
//
// An empty options object extracts every page with the default clean-up. Set `pages` to limit the extraction.
// ---- code: false ----
// <!-- page 1 -->
