Done! Thanks for help.
Now I come to the second step of my project that I explained in my second last post in detail that I need to take the question and different options from the user. Then I need to combine/ merge them together in a format of a Multiple Choice Question(MCQ) and display this MCQ on the webpage. As well as I need to store the complete image(MCQ) in the database.
What do you suggest, should I utilize all the input in one go(question + options) and try to bring them in one variable (using some formatting commands/ operators of Latex) and send them for rendering. In this way I hope to get one image for the complete question. (will it be possible and whether Latex help me to format the input to get the desired formatted output)
OR should i take all the inputs as images separately; question separately and all other options separately. Then I merge them to get the desired format of question.
Also mention the appropriate functions or examples if possible.
