Here's a tip for students who would like to utilize the Surfer (or Grapher), application off-line on their own computer, but can't afford the product.
Basically if you are a student you can get a 1 year license for Surfer (or Grapher) for $50 by following these directions:
Thank you for your email and request for information regarding our Student License program. For university students to purchase the $50 annual (per product) license we require the following:
Email us at sales@goldensoftware.com from their university issued email account
Send us a proof of enrollment that includes their name, the university's name, and the current enrollment period (including the year)
Once this information is received, we send them a coupon code for them to purchase their license through our web store. It is one-year license that will automatically expire one year after purchase.
However, now that CalcImage contains shape, polygon and profile extraction features as described here:
