This class can be use to render mathematical formulas as graphical images.
It parses a formula with constant and variable values combined with several possible mathematical operations.
Currently it supports formulates using the operations: addition, subtraction, multiplication, division, and functions like square root, sin arc sin, cosine, and power.
Then it renders the given formula in an GD library image. It uses a given True-Type font to render the formula characters.
The class returns a GD library image resource handle that can be used to output the formula image in any format supported by the GD library.

Mathematical formulas are often used in scientific documents. The formulas need to be parsed and rendered in a special way to be presented adequately, using special layout methods and fonts that are not always available with all browsers. This class can render mathematical formulas using server side generated images. This way it can display the formulas so they appear correctly in all browsers. Manuel Lemos |
