The attached project demonstrates the implementation of two of our Javascript Image Processing commands with our HTML5 Image Viewer. It implements the Sharpen command and the Gaussian command. The Javascript logic is defined in "Scripts/App.js".

The project demonstrates usage of the following classes and methods in the Leadtools HTML5 / Javascript API:

Leadtools.Controls.js
Leadtools.Controls.ImageViewer
Leadtools.Controls.ImageViewer.add_changed
Leadtools.Controls.ImageViewer.set_sizeMode
Leadtools.Controls.ImageViewer.set_defaultInteractiveMode
Leadtools.ImageProcessing
Leadtools.ImageProcessing.set_jsFilePath
Leadtools.ImageProcessing.set_command
Leadtools.ImageProcessing.get_arguments
Leadtools.ImageProcessing.run
Leadtools.ImageProcessing.set_imageData

I have updated this to use the latest v19 Javascript SDK. I also added more functionality so now it will do Flip, Reverse, Invert, and change the Contrast/Brightness and Intensity.
