Re: [ferret_users] how to make big picture and 2 separate pictures by one script

[Ryo Furue <furue@xxxxxxxxxx>]

Hi Ferret users,

| A concrete example based on gs (Ghostscript) and convert
| (ImageMagick), is
| 
| $ cat myscript.jnl
| use levtitus_climatology
| shade temp[k=1]
| 
| $ ferret -batch myscript.ps -script myscript.jnl
| $ gs -q -dNOPAUSE -dBATCH -sDEVICE=pnmraw -r300x300 -sOutputFile=-
| myscript.ps | convert - myscript.gif

The last command can be simplified to

  $ convert -density 300 myscript.ps myscript.gif

Of course this is much less flexible than the original method,
as demonstrated below.

| I get a 2550x3300 pixels image.
| 
| You can also crop and rotate the image by piping pnm commands (Netpbm)
| $ gs -q -dNOPAUSE -dBATCH -sDEVICE=pnmraw -r300x300 -sOutputFile=-
| myscriopt.ps | pnmcrop | pnmflip -r270 | convert - myscript.gif

Thank you for this!  It's a great capability.

Regards,
Ryo
