I want to create an image generation for a vinyl lettering website. It will need to have similar functionality as [url removed, login to view] or [url removed, login to view]
1. dynamically generate image using color, font files, and user input text
2. dynamically calculate the price of vinyl lettering using our formula
3. dynamically add the custom product to the Zencart shopping cart including all the custom variables of color, price, font. and phrase.
