Flex Programming Task

In order to be considered for the Flex position we ask you to complete the following steps.

Note: This task should take no longer than 1 hour to complete. Please read the entire project spec before you start work.

Prerequisites

• This task requires some ActionScript3, Flex and git knowledge.
• You will need to have a Flex IDE (Flash Builder ideally) installed to complete this task.

Task

• The goal is to build a simple LaTeX editor which returns a gif image to Flex based on an equation the user enters into a text field similar to the one you can see at http://www.codecogs.com/eqnedit.php. The user can also click buttons to create the equation.

1. Fork this public repository (if you don't know how to do that, Google is your friend)
2. Create a Flex 4 project with a src folder to contain your code.
3. In the src directory, please create a Flex app that accomplishes the following:
   • Provide a text input field to the user to enter equation text
   • Provide 3 buttons with LaTeX symbols of your choice which, when clicked, add the clicked symbol into the text field (see http://www.codecogs.com/eqnedit.php for an example). If you have time feel free to add additional buttons
   • Requests/loads new image data by HTTPService from 'http://latex.codecogs.com/gif.latex?\LARGE%20\bg_white%20[equation]' upon every change of the text field. A valid example for the equation 1+1 would be 'http://latex.codecogs.com/gif.latex?\LARGE%20\bg_white%201+1'
   • Display the image data returned from the HTTPService in an image underneath the text field
4. Comment your code where you feel appropriate

Once Complete

1. Commit and Push your code to your new repository
2. Send us a pull request, we will review your code and get back to you
