|The Transform Programmer|
|Navigation Toolbar||The Transform Programmer is a package of programs
for the PC's running Windows which work together to support exploratory
learning and enjoyable activities involving geometric transformations.
The Transform Programmer consists of three main parts -- (a) an image processing and display subsystem called the "METIP Programming Environment," (b) a programming language interpreter, in this case, the XLISP-STAT system of David Betz and Luke Tierney, and (c) a particular Lisp program that facilitates the manipulation of mathematical expressions. The first component, METIP Programming Environment, provides a user interface very much like that of the Pixel Calculator program. The differences are that multiple images can be handled at the same time, that the program contains the capability to transform images in complicated ways according to user-specified formulas, and that the image display and transformation functions can be commanded from the programming language as well as directly by the user. The programming language makes it possible to explore computer programmming and image processing together, if students or teachers so desire.
The Transform Programmer allows the specification of a general mathematical formula to apply to one or more source images. The general nature of the interface allows for a high degree of experimentation on the part of the student and supports interactive activities. The formula can be expressed in cartesian or polar coordinates and allows for the value of a pixel in the result image to be a function of arbitrary pixels in the source image(s).
You may want to take a look at the Transform Programmer README file before you download the software.
