Progress Telerik UI for ASP.NET Core
Image Editor
-
Overview
With the Telerik UI for ASP.NET Core Image Editor component your users gain the ability to modify image files in the browser without installing third-party software or opening an external application. The control is driven by the HTML5 Canvas element. It provides several built-in commands for loading, cropping, resizing, zooming and downloading the edited image.
-
Resizing
To make matters simple, some of the Image Editor’s instruments like the Resize tool use a dedicated panel on the right-hand side of the control. This panel displays UI to edit both dimensions of the image and a checkbox to lock the aspect ratio. While the user is experimenting with the correct sizes, a preview will be shown. Through the Undo and Redo buttons they can easily revert or reapply the change to the image before deciding on what works for them.
-
Cropping
Similarly, to the Resize command, cropping also uses a dedicated panel. The panel contains options to tweak the aspect ratio, orientation, width and height of the cropped version. Users can again preview the results and use the Undo and Redo buttons to revert/reapply the change if needed.
-
Zoom Options
To zoom in or out on an image, users can use the zoom controls on the top of the editor:
- Zoom-in button
- Zoom-out button
- Dropdown to choose between “Fit to Screen” (to scale the entire image to fit in the display area of the control, usually by downscaling) and “Show Actual Size” (display the entire image in its full resolution with scrollbars if necessary)
-
Keyboard Navigation
The Image Editor is one of the many components in the Telerik UI for ASP.NET Core suite with out-of-the-box support for keyboard navigation.

Image Editor Theming
<div u-fs24"="">The Telerik ASP.NET Core Image Editor has 20+ built-in themes such as Default (our own styling), Material (based on the Material Design guidelines) and Bootstrap (which looks like the Bootstrap styling to integrate better). You can easily customize any of out-of-the-box themes with a few lines of CSS, or create new theme to match your colors and branding by using the Telerik SASS ThemeBuilder application.
