Hi,
using "frame" repeatedly with the same file name produces files
with an additional extension. Just use the unix command 'ls' to
explore this.
What image files are suitable for you depends on the software to
compile the animation. There is a simple old tool 'whirlgif' to
produce an animated gif. Its nice and easy to use, but vanishs out
of sight of google. It requires gif input. Please note, the most
favourable version of ferret, namely pyferret does not support gif
anymore but produces png-files. If you need gifs just write a
little shell script using the ImageMagic tool 'convert' to produce
gif files. Something like
files=`ls *png`
for file in $files
do
name=`echo $file | cut -f1
-d.`
echo
$name
convert $name.png
$name.gif
done
More complex tools like mencoder can be used to glue a sequence
of png-files.
But now to ferret. Just organise a loop over the time slices. It
is easy to generalise it for more than 12 steps.
use coads_climatology
repeat/l=1:12 (\
shade/pal=blue_orange sst;\
let li=`l`;\
define symbol stamp=`li,zw=3`;\
define symbol filename=sst_($stamp);\
sp rm ($filename).png;\
frame/file=($filename).png/format=png/ypixel=1024;\
)
You may guess the reason for the complex way to build the
filename. Using ls *png produces the file list in the correct
order, not only for 12 time slices but also for a larger number
(<1000 or for more with zw=4). This allows to produce an
ordered list of files to be glued to an animated file with a
single unix command ls sst*.png > filelist.
Hope this helps to get you started.
Best,
Martin

Subject: [ferret_users] for multiple png or gif file
for the use of animation
i want to create multiple
png or gif files to produce animation which is my next
concern step. i am having the latest pyferret and ferret
and by the use of pyferret i am doing in this way
REPEAT/L=1:12 (FILL SST;
GO fland; FRAME/file=sst0_`l`.gif)
but i am getting only a
single image of the last time step instead of 12 images
which i want to use in further animation.
apart from this i also
want to ask that can i create multiple .png files for my
animation and for the beautification of my plots how to
issue multiple commands like ppl tics, shakey, conset
etc. in this excercise.
i hope i will get help on
this regard.
