34 Chapter 2: Importing and Exporting Data
Using File Open
Selecting a data file using File → Open will open the file using the default iTool file
reader for the type of file you select. The data will be added to the Data Manager and
the iTool will automatically create the default visualization for the data contained in
the file.
If the data in the file you select is binary or ASCII, you will be prompted to specify
further information that will allow the binary or ASCII file readers to correctly import
the data. For an explanation of the handling of various file types see the following
sections:
• For ASCII data see “Importing ASCII Data” on page 36
• For binary data see “Importing Binary Data” on page 37
• For ShapeFile data see “Importing Shapefile Data” on page 38
• For data of an unrecognized format see “Working with Unknown Data” on
page 39
Using IOPEN
The iOpen functionality allows you to access many different file types directly from
the workbench rather than from the command line. When you open an image file this
way, it immediately displays in an iImage window. In cases where data displays in an
iTool, data is copied into the iTools Data Manager. (See About the Data Manager for
more information.)
When you open other available data types, the data variables contained in that file are
read into IDL’s scope and are made available in the IDL Variables View. You define
the variable names when you use this method. See IOPEN for more information.
