to recover writings that have been damaged or erased. It is distributed
free-of-charge,
without warranty. The current version is 2.3, released on 29 November 2024.
New Features in version 2.3
Three new modules were added to the Cupboard, ImFill, Pause, and WriteStack.
ImFill replaces outlier values, within a window, with
that window’s average value.
Pause is used in a flowchart to introduce a short delay. WriteStack will write out
several images, one for each band of the input image.
One major change on Hoku for
Macintosh computers, is that the new Mac version
of Hoku will run on both a computer with an M-chip, or
the older Intel chip.
As a result, there is now only one version of Hoku
for the Mac. There is also only
one version for Windows. A Linux version is under development.

Full instructions on how to install Hoku
are contained in the “Instructions” text file
within each folder. Installing Java on your computer is not needed for these
applications.
Hoku has the necessary Java runtime code embedded
within it.
To install the new Hoku
application on a Mac, you must have system administrator
privileges on your computer. If you do not have such privileges, see if a
system
administrator will load the software for you. Administrator privileges are not
required
on Windows.
Upgrading your Hoku version
On Windows, to upgrade Hoku from an
earlier version, you will need first to uninstall
any previous Hoku that is currently installed. On the
Mac, it will ask you if it can uninstall
the previous version for you, as you install the new version.
Your existing data, on your Hoku
Shelf and Hoku Desktop will not be changed.
All of your existing data will be available to you in the new version of Hoku.
