Raster *.cal extension file to *.dwg

I need to take a folder full of scanned ????.cal files and have a routine that initializes AutoCAD, inserts next ????.cal file then saves both a ????.dwg and ????.cal file back to the same folder. It needs to loop through all files unattended. I use AutoCAD 2002 with RasterDesign3 being loaded when AutoCAD starts.
Any suggestion??

 

I do this all of the time.
first I use a quick batch file to create a text file of all of the .cal names in a directory
dir *.* /b >c:\textfiles\filenames.txt
Then I use a simple script written like lisp file to insert the cal files one by one
(setq filenam (open "c:/textfiles/filenames.txt" "r"))
(while
(setq ImageFileName (read-line filenam))
(setq fullfile (strcat "c:/plot/" ImageFilename))
(command "image" "attach" fullfile "" "" "")
(command "zoom" "e")
(command "saveas" filename)

after you have saved the file, erase and detatch the image

(command "erase" "all" "")
(command "image" "detach" "*")
);;while
(close filenam)
Hope this helps

 

Thanks,
I'm on vacation for two weeks so I'll give it a try when I return
