How to retrieve current RAW import parameters non-interactively?

[Josh Doe-2]

Hello,
I deal with many RAW images, each of varying dimensions and varying
header sizes. Doing File->Import->Raw each time I wish to open a new
image gets very tedious.

What I would like to do is add a section of code to the
HandleExtraFileTypes.java plugin. After the image fails to match any
supported formats, my bit of code would then non-interactively attempt
to open the file using the last used RAW import parameters. What I
have now is as follows:

//Try to open as RAW image
ImportDialog impdlg = new ImportDialog(name,directory);
FileInfo fi = impdlg.getFileInfo();
if (fi!=null) {
  FileOpener fo = new FileOpener(fi);
  imp = (ImagePlus)fo.open(false);
  if (imp!=null)
    return imp;
}

This allows me to drag and drop RAW images or use File->Import->Image
Sequence, HOWEVER I have to accept the dialog settings for every
single image.


Is there a way to retrieve the settings used with the import RAW
dialog box without actually displaying the dialog? Right now all the
required variables or private members. I know I can retrieve the
parameters from the prefs file, but that only contains the settings
used from a previous session of ImageJ. I would like to be able to
open one image successfully in ImageJ and then use those same settings
from then on.

Thanks for any suggestions!

Use the ImportDialog.getLastFileInfo() method, which was added in
ImageJ 1.39t, to retrieve the settings used by the File>Import>Raw
command. You can upgrade to v1.39t by using the ImageJ_Updater plugin
(http://rsb.info.nih.gov/ij/plugins/imagej-updater.html) and selecting
"daily build" from the drop down menu. The release notes for the daily
build are at <http://rsbweb.nih.gov/ij/source/release-notes.html>.

Excellent, close to perfect. However it appears that
ImportDialog.getLastFileInfo() only returns a non-null result if I
actually click on File->Import->Raw.

I'd like to be able to open ImageJ, drop a RAW file on the window,
prompt me for the parameters, and from then on all images are opened
without a dialog.

I think the problem has to do with the fact that I'm using new
ImportDialog, rather than using the existing instance of ImportDialog,
so getLastFileInfo() isn't aware of my calls. Here is what I have so
far. Any suggestions? Thanks!

//Try to open as RAW image
FileInfo fi=null;
if(IJ.versionLessThan("1.39t")==false)
  fi = ImportDialog.getLastFileInfo();
if(fi==null) {
  ImportDialog impdlg = new ImportDialog();
  fi = impdlg.getFileInfo();
}
if (fi!=null) {
  fi.fileName=name;
  fi.directory=directory;
  FileOpener fo = new FileOpener(fi);
  imp = (ImagePlus)fo.open(false);
  if (imp!=null)
    return imp;
}
