Set Flip Mode when Converting to a Image Format

With our latest release 19.3, some new properties are introduced in ImageSaveOptions class. When converting to a Image format you can now always set brightness and contrast. API permits you to do mirror-reversal across a horizontal/vertical axis using FlipMode property. Based on your feedback, we resolved some previously logged issues and improved document conversion experience. Such as, image quality is improved when converting to a WebP format. Furthermore, JpegQuality issue is now resolved for PDF to JPEG conversion.

New Properties in ImageSaveOptions

FlipMode offers horizontal, vertical, horizontal and vertical at the same time or no Flip at all. Control gamma correction, brightness and contrast when converting to a image format.

Fix – ImageSaveOptions.JpegQuality Issue

You can select desired image quality when converting to JPEG format. Quality scale must be between 0 and 100. Previously, despite of setting JpegQuality to any value (0-100), API was not reflecting any change in the output. This issue is now fixed.

GroupDocs.Viewer for .NET 19.3 is Released!

Document Viewer API

We are happy to announce the release of version 19.3 of GroupDocs.Viewer for .NET. In this release, we have added several new features that target the PDF documents, archives and the source code files of Visual Basic and C#. Along with 2 bug fixes, we have made a couple of improvements for rendering of ZIP archives and vCard documents. For detailed information about the latest release, please have a look at the release notes.

What’s New in this Release?

Setting Passwords and Permissions for PDF Documents

PDF format allows setting the Owner password and the User password to restrict access to the document. The Owner password is used to change the permissions of the document whereas the User password is required when opening a PDF document. Along with the passwords, PDF format supports setting permissions such as allow or deny printing, modification and data extraction. In this release, we have added the support of setting the Owner password, User password, and the file permissions while rendering the document into PDF.

The following is a simple way to create and use the PDF file’s security options using GroupDocs.Viewer for .NET:

Working with Folders within the Archives

In the previous version, we introduced the support of rendering archive documents. The rendering of archive documents shows a list of the items (files and folders) located in the root of the archive. In the latest release, we have made it possible to get the list of the folders within the archive and render the content from those folders. The following sections demonstrate how to work with the folders located in an archive document.

Getting List of Folders within an Archive

The following code snippet shows how to get the list of folders within an archive:

Getting List of Folders in a Specific Folder

There might be the case when you have sub-folders within a folder located in the root of the archive. In that case, to get the list of sub-folders you can simply specify the folder name in ArchiveOptions.FolderName property of HtmlOptions/ImageOptions class.

Rendering Specified Folder within Archive

To render the content of a folder, simply specify the folder name in
ArchiveOptions.FolderName property and call GetPages function as shown in the following code snippet.

Support of Visual Basic (.vb) and C# (.cs) Files

Using the latest release, you will be able to view the source code files of Visual Basic and C#. The rendering of these source code files is available in both, the HTML-based and image-based rendering.

Configurable Redaction using an XML File


A configuration file defines the initial or commonly used parameters, options, settings or preferences applied to operating systems, infrastructure devices or applications in an IT context.

When the Need Arises

If you have large size data (may consist of multiple files of different file formats) or corporate sensitive data which need to be redacted without specifying the rules in your code.

What is the Solution

The GroupDocs.Redaction API provides the way to define a removal policy by writing the list of pre-configured redaction rules in an XML file. Hence, you do not need to specify the rules in your code. You can have as many policies, as you need to redact your documents.

The example of redaction policy XML file is as follows:

How to Apply Redaction Policy

The example below shows:

  • how to apply the redaction policy to all files by giving inbound folder
  • Save the output files to one of outbound folders
  • The successfully updated files and failed one will save to their respected folders
  • The current date and time is used as a part of output file name
  • The successfully updated files and failed one will save to their respected folders

The complete ready to run code sample is available on GitHub.

Rendering Archive Documents

The Compressed files (e.g .ZIP or TAR) use file compression in order to save the disk space. Also, the compressed archive formats can be used to compress multiple files into a single archive. This post demonstrates the usage of the GroupDocs.Viewer API to render the list of files or folders from an archive file.

Rendering the List of a Folder from the Archive

The GetPages method of both ViewerImageHandler and ViewerHtmlHandler renders the items from the root of archives.

The following code snippet shows that how simple is to render the list of items from the root of an archive:

The output of the above code snippet looks as follows:

Rendering Specified Folder into Image, HTML or PDF

To render a specified folder from an archive into image, html or PDF, all ImageOptions, HtmlOptions and PdfOptions classes have the ArchiveOptions.FolderName property which is used like:

ArchiveOptions.FolderName = "FirstLevelFolder";

When you need to render the list of items or folders contained in a certain folder inside the archive, set the value using ‘/’ path delimiter character like:

ArchiveOptions.FolderName = "FirstLevelFolder/SecondLevelFolder";

The following example shows the rendering of a list of items from a folder “SecondLevelFolder” which is contained inside the “FirstLevelFolder” of the archive:

If the rendering into PDF file is required, you can write the code as follows:

The complete ready to run code sample is available on GitHub.
