Exporting Image Data to a File
You can export the pixel data from an image selected in an iTool window into a single
image file using the File → Export Image menu option. Using this option exports
only the image data — no annotations, axes, or other visual items shown in the iTool
window are included.
Tip
It is important to know that the data you modify in an iTool is not changed in the
IDL main scope. Any data variables remain in IDL unchanged. To save the changes
you make to data in an iTool, export the data to IDL. See Exporting Data to the IDL
Session for more information.
This may be useful if you have modified your image data using the items from the
Operations menu, and would like to save the modified image data in its own file.
By default, you can save image data in the following formats:
• Windows Bitmap (BMP)
• Joint Photographic Experts
Group (JPG)
• JPEG2000 (JP2)
• Graphics Interchange Format
(GIF)
• Macintosh PICT
• Portable Network Graphics
(PNG)
• Tag Image File Format (TIFF)
For example, to export an image:
