Full Set of Tools

RadImageEditor can be used in two different render modes - CanvasMode, using the HTML canvas tag where all the changes are made Client-side,and non CanvasMode, where the image editing is handled entirely on the Server. The core of the Server-side editing mode is the .NET standard GDI+ library. You can control the mode of the control through its CanvasMode property (with a value set to "Yes" or "No"). Thanks to the canvas functionality (available since Q3 2012) RadImageEditor has the following filters: Invert Color, Brightness and Contrast, Sepia and Greyscale along with drawing functionality.

Depending on the chosen mode, you can utilize the following sets of tools:

  • All modes supported tools: Print, Save, Undo, Redo, Reset, Crop, Resize, Zoom, ZoomIn, ZoomOut, Opacity, Rotate, RotateRight, RotateLeft, Flip, FlipVertical, FlipHorizontal, AddText, InsertImage (available since Q3 2011), Export (available since Q1 2013).

  • CanvasMode supported tools: All tools from the list above, including BrightnessContrast, InvertColor, Sepia, Greyscale, HueSaturation, Pencil, DrawCircle, DrawRectangle, Line.

The implementation of the RadImageEditor’s toolbar is based on RadToolBar. Still it resembles the toolbar structure of RadEditor, which can be set either:

  • inline in the control’s declaration

  • or via an XML file.

Defining the tools inline

important

When setting the ImageEditorTool tool tags, it is required to specify the CommandName attribute. Other available attributes are: CssClass, Enabled, ImageUrl, Text and ToolTip.
