New features

VIEWERNET-5640

Now it is possible to specify a horizontal and vertical resolution in DPI unit when rendering the input Spreadsheet documents to the raster formats (PNG and JPEG). This is done with the new public properties HorizontalResolution and VerticalResolution in the SpreadsheetOptions class. Both properties default to 96 DPI and can be set within the range [72..600] DPI.

VIEWERNET-5608

A new class MailMessageViewInfo was added in the GroupDocs.Viewer.Results namespace. This class implements and extends its parent class ViewInfo and is returned by the method Viewer.GetViewInfo() when the loaded file is an email message.

How to get the update

NuGet

Upgrade to the latest GroupDocs.Viewer package via the NuGet Package Manager or the .NET CLI:

dotnet add package GroupDocs.Viewer --version 26.4

(Select the appropriate package for your target platform.)
