More File Formats and Font Substitution Options

Some new document formats are also introduced. Like you can do conversion from EPS, TSV, PCL. API also permits to set default font and font substitution option when converting from .one file.

Measure Conversion Time

Can we measure or track time for a document conversion? You might be thinking of such a feature. Because its appealing. Therefore, we’ve introduced this in current release. Let’s have a look at its implementation.

Include Hidden Slides in Converted Document

Yes, this is absolutely right. We’ve implemented a property setShowHiddenSlides using that you can decide either to convert or skip hidden slides when converting a Slide document.


We always introduce improvements for better usability. This release covers following improvements.

  • HideWordTrackedChanges option to WordsLoadOptions class
  • HidePdfAnnotations option to PdfLoadOptions class

Bug Fixes

We listen your feedback carefully and make sure to fix the disruptions that you face. Spreadsheets are one of the best way to represent data. Most of the time you add graphs in it. Previously, API was not converting spreadsheets with graphs properly. It was not showing complete data. However, this issue is now fixed.

Width and Height not Working

Furthermore, there was no impact of width and height in the output that you set in ImageSaveOptions. This issue is also now resolved.

Will we get PasswordProtectedException?

Yes, we fixed obfuscation config for com.groupdocs.conversion.exceptions package. You will now get proper exception on processing a password protected document without applying password. Eventually, this exception could be then handled.
