```
public class Pixmap
extends Object
```
Class for manipulating graphics images, originally developed in C++.
This class represents an image that supports manipulation, i.e., reflection, expansion, inversion, etc. It has an analog in C++, for comparison between the two languages, although there is more support in Java for images than there is in C++.

Creating a pixmap requires a filename that should be a gif or jpg image (or others if getImage() supports them). Currently the filename represents a local image, but changing the URL to support network retrievable images should be straightforward.
Revision history for C++ version:
Modified: 3/21/94 11/29/94 4/13/95
Ported: 10/16/1996 to Java (Syam Gadde) re-implemented, ported to 1.1 6/1/97 (Owen Astrachan)
