The v15.2 Rich Text Editor boasts some exciting new enhancements on both the WinForms and WPF platforms.   

Custom Draw via Layout API

One powerful feature coming soon is the ability to replace page elements. Using the Layout API, you can now draw lines, shapes and text above, below or in place of an element. For example, the image below demonstrates text drawn over an existing image, and blue rectangles in place of the text blocks.

Custom Draw 

Interacting with the document is achieved by subscribing to the RichEditControl.BeforePagePaint event and substituting the default Painter object with a customised descendant.

Nested Comments

With this release, we have added the ability for end-users to respond to comments inside a document, each reply is displayed in a conversational manner using groups making this a powerful collaboration tool.

Improved PDF Export

The engineering teams are always looking to increase performance where possible, and in v15.2 the PDF Export feature was targeted. You can see from the chart below that the exporting functionality is more that twice as fast, and uses 30% less memory.

Memory and Performance


As always, we would love to hear your feedback on the new features for the Rich Text Edit, and in particular the different use cases for the custom draw functionality.
