problem with getArgument() in macro

[Michael Elbaum]

I'm running a macro from the linux command line and trying to pass it a filename, as in

./Image -macro mymacro.ijm mystack.tif

At the top of the macro I have the lines:

arg = getArgument();
print(arg);
open(arg);

All works as expected if I invoke ImageJ from the directory containing mystack.tif.

However it if sits in another directory, arg is printed but the file is not found, so

./Image -macro mymacro.ijm dir/mystack.tif does not work.


Is there a reason for this, and might it be fixed?


thanks,
Michael

This

  ./ImageJ -macro macro.ijm /Users/wayne/images/blobs.tif

works for me, where the macro (“macro.ijm”)

   arg = getArgument();
   print("arg="+arg);
   open(arg);

located in the ImageJ/macros folder, opens the blobs.tiff image and outputs

   arg=/Users/wayne/images/blobs.tif
