Getting Started with IDL: Images |
|
IDL is ideal for working with image data because of its interactive operation, uniform notation, and array-oriented operators and functions. Images are easily represented as two-dimensional arrays in IDL and can be processed just like any other array. IDL also contains many procedures and functions specifically designed for image display and processing. In addition, the iImage tool allows you great flexibility in manipulating and visualizing image data.
In this chapter, we will image process by entering statements at the IDL Command Line as well as trying out the new iImage tool. This will demonstrate IDL's interactive capability, and will show how easy it is to manipulate your data.
| Note To simplify obtaining useful results from the command line examples in this manual, create a bitmap buffer for your graphic windows and to use a maximum of 256 colors by entering the following command at the IDL command prompt: DEVICE, RETAIN=2, DECOMPOSED=0 |
See Image Display (and the functional category Image Processing) for a brief description of IDL routines for displaying and manipulating images. Detailed information is available in the IDL Reference Guide.
