A Recipe for Converting JPEG Images to
SimpleStruct
You may send JPEG images to the JPL Server where SimpleGen
converts the images to the SimpleStruct format. The images may then
be used in the DataSlate application.
Open the JPL Website with the following address: <http://casde.jpl.nasa.gov/sg_server/
>
A dialog box will appear and ask you to enter your name and
password. This information is available from your instructors.

To begin, enter the following information and click on
'Continue'.
(NOTE: There is limited error-checking, so make sure entries are
accurate and correct)
- Your e-mail address (for notification after processing is
complete): ____
- Name of SimpleStruct (8 characters or less): (Make a folder
and assign a name to it. This name will be the one you select with
the 'Load' button on the DataSlate application. Within this
folder, make a folder for each image you are sending to JPL. Place
each image in its folder. These image folders will have the name
which appears in the channel title window of DataSlate. )
- Number of Themes/Images To Be Inserted Into SimpleStruct:
(pull down menu)______
- Press 'Continue' or 'Reset'.
