Add text to an image with PHP

Your job is to create a simple a PHP sample code how to write text to a specific place on a png image file, with a specific font and font size and then display the resulting png file onscreen for user to save as an image or print out. So basically, I need a simple web form that asks the user to enter three lines of text and the font size for each line. The form also contains the submit button, when clicked a PHP file opens [login to view URL] located at the same directory as the php script, writes the three lines of text to the image and shows the generated image file on screen for the user to save as an image or print. Within the PHP file, it must be possible to define the text areas. A text area is the area to which the text is printed to by the PHP script. The text areas can be defined e.g. with two dots (a pair of X, Y coordinates) that tell the top left corner and the bottom right corner of the text area. It must be also possible to define whether the text area is filled with the text horizontally aligned left or the text horizontally aligned at the center. The text is always written vertically centered to the text area. And it must also be possible to define the font used per each text line, within the PHP file. The font files are located at the same directory as the PHP script. A sample of [login to view URL] and [login to view URL] are included to the project. The server has PHP 5 and gd image library installed. You are not given server access to develop this, you must develop this with your server, when you are done, I'll upload it to my server to test it.
