use the getDirectory command for DM3 images

[Caroline Petitjean]

Hello all,

I have a very simple problem: I want to write a macro to open dm3
images, convert them all to 8-bit tiff images and save them in the same
folder again. But the command

getDirectory("image")

does not work on dm3 images (only on tiff, jpeg and so on). Can somebody
tell me why and/or give me a solution around this problem?

Thanks a lot
Caro

Hi Caro,

getDirectory("image") returns the path to the directory that
the active (foreground) image was loaded from.

As far as I see, the dm3 loader plugin on the ImageJ web site
uses the FileOpener, which calls imp.setFileInfo(fi), storing
the directory information of a file in the ImagePlus.
Thus, getDirectory("image") should work on dm3 images.

I don't have dm3 files to test, but you should see the
directory and filename with "Image>Show info..."
If it is not there, maybe the image was not the result of opening
a dm3 file from disk but e.g. created by "Duplicate"?

Hi,

I can't speak to the image format issues, but perhaps you are looking  
to get a list of the files contained in the specified directory?  If  
so then take a look at...

  http://rsb.info.nih.gov/ij/macros/ListFilesRecursively.txt

or use the macro command getFileList(directory) ...
