Public Class CodecsXlsLoadOptions

'Usage
 
Dim instance As CodecsXlsLoadOptions

Microsoft Excel 97-2003 (XLS) and Microsoft Excel 2007/2010 (XLSX) 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 to use when rasterizing.
