The data is entered using Latex (Latex is a type setting language and is not a WYSIWYG language). The tex software converts the latex code into the required image.

___________________________________________________________________________ _____I am writing this post to explain my project so that you may give me more relevant suggestions:
I have to develop an application that will help us develop a database of questions. These questions will be used for developing tests/ exams. Latex is required to enter scientific and mathematical text. As Latex is not WYSIWYG therefore the data entry person will like to see the output for the latex text. For that my latex code will be rendered and then I will be able to get the
desired output. As my application is web based therefore I think I can use MathTeX. (suggest me anyother better option if you know especially if available in Windows platform) So first thing to deal with is to get the rendered images and display them in desired format. The required format is a question with multiple options (MCQ). In short I need a preview of my question and answer options.
The second issue is that I need to get ONE image which should have question with its options and both should be transformed/ merged in such a way that ultimately one image is obtained from the input(question and options). The requirement of my application is that this complete question should then be saved in the database.
I can get the input for question and options in textarea. Now I need to show the preview as well as transform them into one image so as to store in the database.
Guide me which PHP functions will help me in reading and displaying the images as well as merging the images etc. Any suggestion that can help me in this project will highly be appreciated. Thanks!
