Re: Photo

I would be really grateful if someone could give me a brief explanation
of what the photo utility does and how the images created using chop.pl
are linked to whatever photo creates. 

I can't seem to find any information on it other than the two threads
included below.

I'm trying to work out  what the following means.

Usage photo root image(base) xdiv ydiv x0 y0 x1 y1 x2 y2 x3 y3

Apologies if I have missed a readme relating to this.

Many Thanks in advance

"Hi,

I have downloaded and have run FlightGear Scenery Designer which runs
really well.  I have loaded a Satellite image from geoengine.nima.mil
into the designer which again works really well.  It was only then
that I realised that FGSD doesn't export the images to the output
directory.

So back to command line utils.  I guess the tool that I need to use
is 'photo' in 'prep' in TerraGear.  The command line that I run is:

./photo ./output ../../nimadata1048254311.jpg 16 16 -3.31 53.55 -3.31
53.23 -2.69 53.23 -2.69 53.55

but the files it generates aren't what I expected.  I get files with
numeric file names containing hole information.  I was expecting to
get the rgb files, etc as per the KSJC example download.  

I may be running the wrong tool or have misinterpreted the command
line options.

Can anyone please give me some guidance.

Many thanks, in anticipation.

Dave"
