5. Reading the names of your image files from another file.
This example is identical to second part of example #4 except that
the image filenames are all taken from a "file_of_filenames", and
we force the map to be initially displayed.
Recall that in example #4, the file descriptors looked like:
For the example shown below, the only parameter needed is:
The file fnamelist.txt contains:
#this is a comment
TIR1.GIF "Aug 3 12:15pm CDT" overlay = TSFC1.GIF, TSTR1.GIF, TMAP.GIF
#another comment -- note you must explicitly define each file on each frame!
TIR2.GIF "Aug 3 1:15pm" overlay= TSFC2.GIF, TSTR1.GIF, TMAP.GIF
TIR3.GIF "Aug 3 2:15pm " overlay=TSFC3.GIF, TSTR1.GIF, TMAP.GIF
TIR4.GIF "Aug 3 3:15pm" overlay =TSFC4.GIF, TSTR1.GIF, TMAP.GIF
# end of file
(The spacing is shown only to illustrate the flexibility
available.) Note that the frame labels are optionally imbedded
within the file_of_filenames data.
To force the overlay basemap to be initially "on", we add the
"/on" parameter to the end of the map's overlay_labels tag. So the complete
configuration file now reads:
