CodecsExcelLoadOptions Class

Summary

Provides the options for loading Microsoft Excel (XLSX) and Excel 97-2003 (XLS) documents as a raster image.

Syntax

C#
VB
C++
Java
public class CodecsExcelLoadOptions  
Public Class CodecsExcelLoadOptions  
public class CodecsExcelLoadOptions 
public ref class CodecsExcelLoadOptions  

Remarks

Microsoft Excel (XLSX) and Excel 97-2003 (XLS) 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 - XLS/XLSX Format.

Important note

The XLS and XLSX file formats support only the following rasterization size modes:

All other size modes will be treated as CodecsRasterizeDocumentSizeMode.Fit.

The XLS/XLSX file formats do not support loading a document using different horizontal or vertical resolutions. So if the value of CodecsRasterizeDocumentLoadOptions.XResolution and CodecsRasterizeDocumentLoadOptions.YResolution are different, the XLS/XLSX codecs will use the larger of the two values as the resolution when rasterizing.

Example

The example below will load the given Microsoft Excel file (XLSX) and render it as a raster image.

C#
using Leadtools; 
using Leadtools.Codecs; 
 
 
public void CodecsExcelOptionsExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.Xls"); 
 
   // 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 sheet in a separate page 
   codecs.Options.Excel.Load.MultiPageSheet = false; 
 
   // Load the source file 
   using (RasterImage image = codecs.Load(srcFileName)) 
   { 
      // Show the image information 
      Console.WriteLine("Image has {0} pages", image.PageCount); 
      Console.WriteLine("Image size: {0} by {1} pixels at {2} by {3} DPI", 
         image.ImageWidth, image.ImageHeight, image.XResolution, image.YResolution); 
   } 
 
   // Clean up 
   codecs.Dispose(); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
