Hi,
this has been answered previously, in September last year.
If you test versions of printtarg back to 1.5 and possibly prior,
you will notice that the layout is unchanged, ie. it has nothing
to do with the printtarg -r flag, it is simply showing the patches
in the order they are in the .ti1 file, ie. the layout is not being
randomized.
V1.6 added the -B option for black patches, with a default value of 4 for
grey or RGB spaces, as well as the default 4 white patches. These are
deliberately
distributed throughout the samples, and there is also de-duplication of other
patches of the same color generated by the other flags.
If you remove the default white and black patches
(ie. targen -v -d5 -s43 -e0 -g43 -B0 -f0 -p3 NNN)
then you will perhaps see something a bit more like what you expect.
You can of course sort the patches manually by editing the .ti1 file.
