Image Capture and Storage:

Step 3  

This step involved the assembly of the CRISTAL macro statements
necessary to synchronize the loading of the image files in the
graphics environment with the display in the worksheet
environment of the alphanumeric data associated with the
displayed image.  If the structure of the information associated
with each image is essentially the same, then the only difference
between each macro will be the unique filename assigned to the
images associated with each particular resource record.  The
macro used in the example is:

&ILOAD FILENAME

Filename is simply the unique name (and directory or path)
assigned to each particular resource image.  The default file
extension assigned to each Targa image is [.TGA].  Other
extensions can be specified according to the format of the image
file.  In any case, a valid extension must be included with each
specified image filename.  

Example:  The Paradise Inn, an historic hotel at Mt. Rainier, 
has an associated image file named "RPARA1.TGA."  The macro
statement located in cell [C25] is "&ILOAD RPARA1.TGA."  In this
case, the macro assumes that the image file "RPARA1.TGA" is
located in the current (or default) image directory.  

The default directory can be changed by activating the
Environment menu, [/ E D], from the worksheet environment and
specifying another default image file directory.  An alternative
to changing the image directory in the Environment menu is to
specify the path in the macro statement itself (i.e. "&ILOAD
C:\NPS\MORA\RPARA1.TGA").  In this case, the image file
"RPARA1.TGA" is located in the "MORA" subdirectory of the "NPS"
directory on the "C:" disk drive of the system.

Once the image management macro statements were created, the
worksheet was saved under the filename "MORA.CRS" before
proceeding to the next step.  This was done by pressing the [/ F
S R] key sequence and responding to "Save Sheet Filename" query
with "MORA.CRS."  The quick save Function key [F2] can also be
used to save the current worksheet to the current filename.
