Image Editor and Image Editor Toolbar controls

The first great addition to the suite are the RadImageEditor and RadImageEditorToolbar controls. For those of you who are not familiar with the ImageEditor control, it enables you to easily view and edit images in different file formats. The toolbar control is specifically designed to further enhance the editor as it exposes all its editing capabilities and is open to easy customization from your side. Below you can see a picture of some of the operations (resize and crop transformations, hue effect) applied to an image through the RadImageEditor control:


The key features of the element include: 

  • Import and export images in different formats such as JPEG, PNG. GIF and BMP can be imported only for viewing purposes for the time being.

Map Control

The next big addition is the Map control. Its main purpose is to visualize rich spatial data. The control provides visualization of ESRI shape files that consist of geometric objects, such as lines, polylines and polygons. Such objects are commonly used to display various schemes, for example floor plans and seats distribution, all the way to parts of maps for countries, roads, rivers, etc. The following picture shows the map control used to represent data related to all states in the USA:

The library is built for .NET Standard and comes with support for a large set of the features defined in the PDF format specification. With the API and its exposed editors, you can insert images, draw on the document, add text or modify interactive forms. Don’t hesitate and try it out using the FirstLook example in the PdfProcessing section within the Demo application.
