CodecsDocLoadOptions Class

Summary

Provides the options for loading Microsoft Word (DOCX) and Word 97-2003 (DOC) documents as raster images.

Syntax

Java

WinRT C#

C++

public class CodecsDocLoadOptions

Public Class CodecsDocLoadOptions

public sealed class CodecsDocLoadOptions

public class CodecsDocLoadOptions

function Leadtools.Codecs.CodecsDocLoadOptions()

public ref class CodecsDocLoadOptions

Remarks

Microsoft Word (DOCX) and Word 97-2003 (DOC) files have no physical width or height in pixels. Use the CodecsRasterizeDocumentOptions to control how the final document is rendered as a raster image. For more information, refer to CodecsRasterizeDocumentLoadOptions.

For more information, refer to File Formats - DOC/DOCX Format.

Important note: The DOC/DOCX file format supports only the following rasterization size modes:

All other size modes will be treated as CodecsRasterizeDocumentSizeMode.Fit

DOC/DOCX also does not support loading a document using different horizontal or vertical resolutions. So if the value of CodecsRasterizeDocumentLoadOptions.XResolution and CodecsRasterizeDocumentLoadOptions.YResolution are different, the DOC/DOCX codecs will use the larger of the two values as the resolution to use when rasterizing.

Example

This example will load the given Microsoft Word file (DOCX) and render it as a raster image

using Leadtools; 
using Leadtools.Codecs; 
 
public void CodecsDocLoadOptionsExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.doc"); 
 
   // Enable using the RasterizeDocumentOptions 
   CodecsRasterizeDocumentLoadOptions rasterizeDocumentLoadOptions = codecs.Options.RasterizeDocument.Load; 
   // Fit the document at 8.5 by 11 inches at 96 DPI keeping the aspect ratio 
   rasterizeDocumentLoadOptions.SizeMode = CodecsRasterizeDocumentSizeMode.Fit; 
   rasterizeDocumentLoadOptions.PageWidth = 8.5; 
   rasterizeDocumentLoadOptions.PageHeight = 11; 
   rasterizeDocumentLoadOptions.Unit = CodecsRasterizeDocumentUnit.Inch; 
   rasterizeDocumentLoadOptions.XResolution = 300; 
   rasterizeDocumentLoadOptions.YResolution = 300; 
 
   // Load each page at 1-bits/pixel 
   codecs.Options.Doc.Load.BitsPerPixel = 1; 
 
   // Load the source file 
   using (RasterImage image = codecs.Load(srcFileName)) 
   { 
      // Show the image information 
      Console.WriteLine("Image has {0} pages", image.PageCount);

         image.ImageWidth, image.ImageHeight, image.XResolution, image.YResolution);

   // Clean up 
   codecs.Dispose();
