[Debian-med-packaging] Bug#859398: imagej: default memory "allowance" too little

[Jonas D]

Package: imagej
Version: 1.51i+dfsg-1
Severity: normal
Tags: lfs patch

Dear Maintainer,


ImageJ limits the amount of total RAM it (the JVM) will allocate
when loading images etc. On Linux systems, this amount is
defined on startup (within the /usr/bin/imagej shellscript) and
(other than on Windows) cannot be changed during runtime.

The amount is currently fixed to 500MB, which (artificially)
prohibits loading of larger 3D volume datasets as typical
in tomographic imaging applications.

I propose to change the default setting to 4000MB, which is
the maximum possible value as stated in the imagej shellscript.

A corresponding patch is attached.


Kind regards,
Jonas
