Sample images on local folder

[Samuel Meulenyzer-2]

Hi all,

I would like to know if it is possible to change the access of sample images ( 'File->Open samples') which is in the original ImageJ pack directly accessing by URL link (for example  :   http://rsb.info.nih.gov/images/boat.gif ) by a local folder link (for example : c:/program files/imagej/sample images) ?

Thanks a lot.

SM

Hi Samuel,

as I understand the Prefs.java code, thats not so easy:
It seems that this value, which is in JI_Props.txt inside
ij.jar cannot be overwritten by a value in IJ_Prefs.txt.
Thus you have to edit it into the IJ_Props.txt:

Open ij.jar with a .zip utility (or temporarily rename it to
ij.zip, then open it).
There open the file IJ_Props.txt with a text editor, and edit
the line

images.location=http://rsb.info.nih.gov/ij/images/

You can replace the URL with whatever you like, e.g.
   file://home/disk1/jonny/imagejsamples/
and also probably with any directory name not having the
"file://" prefix.

You have to do this each time you update ImageJ by replacing
the ij.jar file.

Samuel,

you can put all sample images in an 'images' folder inside your imagej
folder and

add the following 2 lines to StartupMacros.txt

installdir = getDirectory("startup");
call("ij.Prefs.setImagesURL", installdir+"images/");
