CodecsDocLoadOptions Class

Example 





Members 
Provides the options for loading Microsoft Word 97-2003 (DOC) and Microsoft Word 2007/2010 documents as raster images. .NET support WinRT support
Object Model
CodecsDocLoadOptions Class
Syntax
public class CodecsDocLoadOptions 
'Declaration
 
Public Class CodecsDocLoadOptions 
'Usage
 
Dim instance As CodecsDocLoadOptions
public sealed class CodecsDocLoadOptions 
function Leadtools.Codecs.CodecsDocLoadOptions()
public ref class CodecsDocLoadOptions 
Remarks

Microsoft Word 97-2003 (DOC) and Microsoft Word 2007/2010 (DOCX) 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.
