Example

This example will check the version of a PDF file and convert it to PDF 1.4 if required.

using Leadtools.WinForms; 
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Controls; 
using Leadtools.Drawing; 
using Leadtools.ImageProcessing; 
using Leadtools.Pdf; 
using Leadtools.Svg; 
 
 
public void PDFCompatibilityLevelExample() 
{ 
   string sourceFileName = Path.Combine(LEAD_VARS.ImagesDir, @"Leadtools.pdf"); 
   string destFileName = Path.Combine(LEAD_VARS.ImagesDir, @"LEAD_14.pdf"); 
 
   // Check the version of the source file 
   PDFFileType fileType = PDFFile.GetPDFFileType(sourceFileName, true); 
   if (fileType == PDFFileType.Unknown) 
   { 
      Console.WriteLine("Not a valid PDF file"); 
      return; 
   } 
 
   if (fileType == PDFFileType.PDF14) 
   { 
      Console.WriteLine("Is PDF 1.4 already"); 
      return; 
   } 
 
   // Not PDF 1.4, convert 
   Console.WriteLine("Converting to PDF 1.4"); 
   PDFFile file = new PDFFile(sourceFileName); 
   file.CompatibilityLevel = PDFCompatibilityLevel.PDF14; 
   file.Convert(1, -1, destFileName); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
