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. .NET Core C#

//  Load the PDF and call `ExtractText` with the operation and an options object. The result is returned as JSON:

//  ```

//  success = pdf.ExtractText("text",json,jsonOut);

//  An empty options object extracts every page with the default clean-up. Set `pages` to limit the extraction.
