Write(string) Method

Summary
Writes the created file from memory to the file system using the path provided.

Syntax
C#
C++/CLI
Python
public void Write( 
   string outputFileName 
) 
public: 
void Write(  
   String^ outputFileName 
)  
def Write(self,outputFileName): 

Parameters

outputFileName
The name of the output file to be saved.

Remarks

The PDF Compressor object normally creates the compressed PDF document file in memory. It can add as many pages as required to the file. Once the PDF file in memory is complete, call this method to write the file to disk, before calling the Dispose method.

For more information, refer to Creating a Compressed PDF File.

Use PdfCompressorEngine.Write(Stream) to write the result to a .NET stream.

Example

This example inserts an image into a PDF document without using the MRC.

C#
using Leadtools; 
using Leadtools.PdfCompressor; 
using Leadtools.Codecs; 
 
 
public void pdfCompressor_SegmentImage_PdfDocument(object sender, PdfCompressorSegmentImageEventArgs e) 
{ 
   //This will prevent addition to any segment with type background in all pages except the first page only 
   if (e.Page != 0 && e.Segment.Type == SegmentTypeFlags.Background) 
      e.Cancel = true; 
   else 
      e.Cancel = false; 
 
} 
 
public void PdfCompressorExample_PdfDocument() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "MRCSegmentation.mrc")); 
 
   PdfCompressorEngine pdfCompressor = new PdfCompressorEngine(); 
   PdfCompressorCompressionTypes compressionTypes = new PdfCompressorCompressionTypes(); 
 
   //Sets compression types needed for each segment 
   compressionTypes.Comp1Bit = PdfCompressor1BitCompression.Zip1Bit; 
   compressionTypes.Comp2Bit = PdfCompressor2BitCompression.Lzw2Bit; 
   compressionTypes.CompPicture = PdfCompressorPictureCompression.JpgPic; 
   compressionTypes.QFactor = 2; 
   //Flags for used compression types should be set 
   compressionTypes.Flags = EnabledCompressionsFlags.EnableOneBit | 
      EnabledCompressionsFlags.EnableTwoBit | 
      EnabledCompressionsFlags.EnablePicture; 
 
   pdfCompressor.SetCompression(compressionTypes); 
 
   pdfCompressor.Insert(image); 
   pdfCompressor.SegmentImage += new EventHandler<PdfCompressorSegmentImageEventArgs>(pdfCompressor_SegmentImage_PdfDocument); 
   pdfCompressor.Write(Path.Combine(LEAD_VARS.ImagesDir, "Out_Image.pdf")); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
