Here is what we need:
We need a system able to run on Windows and able to communicate as a web service. What the system is supposed to do is basically get a bunch of elements with their respective coordinates and information sent in json format and put those in jpeg/pdfs files. These files will be get from a folder containing them and we will specify which file it will get.
Also, it needs to save the file generated, maintining the DPI and quality from the original file read and generate a thumbnail so the user can see the result in the screen. The response has to be returned in json format using the structure that we specify.
The process is read, put and save. We dont need a special interface for the website since we will send everything and it just generates.
We need code that performs fast, clean and commented.
