Syntax
Members
MemberDescription
Adaptive Automatically selects the best compression type for each image on the page. JPEG will be used for large images with many unique colors. DEFLATE will be used for all other images.
Deflate A lossless data compression.
JPEG A lossy data compression.
JPEG2000 A lossy data compression.
LZW Lempel-Ziv-Welch, a lossless data compression.
None No compression.
RLE Run-length encoded compression.
Example
Layout_ExportPDF
  //Export a layout to PDF

  //Create a PDF export format
  PDFFormat pdf = new PDFFormat()
  {
    OutputFileName = filePath,
    Resolution = 300,

};

  //Check to see if the path is valid and export
  if (pdf.ValidateOutputFilePath())
  {
    await QueuedTask.Run(() => layout.Export(pdf)); //Export the PDF
  }
Export a layout to PDF
//Export a single page layout to PDF.

//Create a PDF format with appropriate settings
//BMP, EMF, EPS, GIF, JPEG, PNG, SVG, TGA, and TFF formats are also available for export
PDFFormat PDF = new PDFFormat()

//Check to see if the path is valid and export
if (PDF.ValidateOutputFilePath())
{
  await QueuedTask.Run(() => layout.Export(PDF));  //Export the layout to PDF on the worker thread
}
Export a map series to single PDF
//Export a map series with multiple pages to a single PDF.

//Create PDF format with appropriate settings
PDFFormat MS_PDF = new PDFFormat()

  ExportFileOptions = ExportFileOptions.ExportAsSinglePDF,  //Export all pages to a single, multi-page PDF
  ShowSelectedSymbology = false  //Do no show selection symbology in the output
};

//Export on the worker thread
await QueuedTask.Run(() =>

  //Check to see if the path is valid and export
