I don't care whether people like diffs or not. I can accommodate with no
complaints. I actually prefer diffs, it's just that I was not sure of the
preferred format here (if there is one) on this list--the lack of repository
and especially the lack of "Here is how you submit patches" brought me to
this view. I figured that if there were some here that preferred
diffs, these would certainly know how to do them, knowing the base
distribution that I specified.
With regards to the important part of my post, yes, stacked PAM (PNM, etc,
etc) images are defined by the format, although there are few of the netpbm
programs that use it. Of course, the most blatant use of the stacked netpbm
format is in the programs 'pnmsplit', 'pamsplit', 'pampick', .... Although
this is not the best format to work with (with respect to compression and so
on), it is certainly an easy format to use with the guarantee that my data is
not altered and easily accessible from various other programs of my own
making (c, c++, octave, ...). I don't think that my changes were too
complicated, but that is just my opinion (especially in the writer).
Oh, and yes, you can actually store information about the image in netpbm.
This can be done in the form of comments instead of some standard header.
Just to set the record straight.
ciao,
Spencer
