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

class CodecsExcelLoadOptions:
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.
The example below will load the given Microsoft Excel file (XLSX) and render it as a raster image.
using Leadtools;
using Leadtools.Codecs;
using Leadtools.ImageProcessing.Core;
public void CodecsExcelOptionsExample()
{
RasterCodecs codecs = new RasterCodecs();
string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "test.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 - CodecsExcelOptions & CodecsExcelLoadOptions reference
codecs.Options.Excel.Load.MultiPageSheet = false;
codecs.Options.Excel.Load.MultiPageEnableMargins = false;
codecs.Options.Excel.Load.MultiPageUseSheetWidth = false;
codecs.Options.Excel.Load.PageOrderDownThenOver = false;
codecs.Options.Excel.Load.ShowHiddenSheets = false; // ShowHiddenSheet reference
// Load the source file
using (RasterImage image = codecs.Load(srcFileName))
{
// Show the image information
Debug.WriteLine("Image has {0} pages", image.PageCount);
Debug.WriteLine("Image size: {0} by {1} pixels at {2} by {3} DPI",
image.ImageWidth, image.ImageHeight, image.XResolution, image.YResolution);
//To save as BMP, uncomment out this line:
//codecs.Save(image, srcFileName + ".bmp", RasterImageFormat.Bmp, 24);
}
// Clean up
codecs.Dispose();
