* It will have advanced image processing features such as

1)  Crop, resize

# Crop, resize

 

# Control brightness, contrast, sharpness, noise  etc.

2)  Control brightness, contrast, sharpness, noise  etc.

# RGB controllers. Three sliders for R, G, B, with which students can increase or decrease respective values of the pixels of the image.

 

# HSV controllers. Three sliders for  H,S,V with which students can increase or decrease respective values of the pixels of the image.

3) Apply effects like sepia ,grayscale ,vintage, lomo etc.

# Apply effects like sepia ,grayscale ,vintage, removing red eye, lomo etc.  

 

# For convolution filters, we can have an input matrix(3*3) in which weights can be adjusted by the students.

4)  RGB controllers. Three sliders for  R, G, B, with which students can increase or decrease respective values of the pixels of the image.

* It will have both mouse and key events. Example: zoom in can be achieved by clicking on icon and '+' key on the keyboard. Similarly others.

* The application will have a Plugin mechanism for adding further effects and features.

* The application will have a Plugin mechanism for adding further effects and features.

* The application will have a  “'''fun facts”''' or “ '''tutorial'''” section. In this section children will be introduced to the world of pixels. How pixels make an image and how they can be manipulated using the ImageViewer application. Each filter will be explained through description/ images/ animations.  This will encourage them to think out of the box and if their effects created through RGB data manipulation  are good enough they can create their own plugin!  The RGB controllers can explain how pixels values can be changed in an image. Incresing all RGB values with the same amount increases the brightness, taking average of RGB values can give grayscale effect, for advance filters like blur,sharpness, edge detection which use convolution filters, an input matrix (3*3)  will be made so that students can enter different weights and see the consequent result. All these will be accompanied by live examples explained thoroughly in the tutorial section. Reference links for further advance study will also be given. ( A demo of this can be seen in the prototype mentioned below)

# Caman.JS- It is a predefined library for effects, It’ll be used only for much advanced effects and filters.

 

* The application will use Canvas 2d and not traditional SVG because canvas is best for pixel manipulation.

* I joined sugar labs a month back and from then I’m only concentrating on ImageViewer activity, I was considering to improve the original python imageviewer as a project but  since this time focus was on JavaScript and a port of imageviewer was required, I learned JavaScript and am determined to make a well designed, structured ImageViewer.

No educational material is complete without Images and Imageviewer is an essential program to view them. Sugarlabs is creating web support for children who can’t afford an OLPC laptop, so Imageviewer in javascript running in any browser will help out to reach many more children who can benefit from sugar.

This ImageViewer in JavaScript will have a new child-friendly UI and many new exciting features.One of the most important benefits of this activity is that it will induce learning. Image processing is a vast field and many creative things can be done through it. My application will '''also''' '''focus on  how children can understand pixel manipulation'''.  Through this they can learn how filters actually work and how they can create their own effects. Creativity has no bounds and when given the right tools one can create unimaginable art work.
