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. Visual FoxPro

*  # 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 -->
*  
*  # 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.
