Before you answer with RTFM I have read the manual and cannot determine the
answer from it.

I would like to try and continue a trace but not from where I left off.  I
have an image that got approximately 75% complete.  I then decided to alter
an element (color in this case) that is somewhere between the 50% and 75%
area.  I want to basically continue the trace but starting from the 50%
point not the 75% point where it is now.  Is there an easy way to do this?

Maybe read section 5.2.2.1.2 again... ;-)

Thanks Christoph.  I still am having trouble determining if the start_row
will simply continue from that point or only render from that point on and
will essentially erase the portion prior to that position when it starts.  I
guess I'll experiment with backups files.  I should have tried that first
anyway.

The Start_Row doesn't work with Continue.  If I use them both the trace
starts at the last line that was rendered rather than actually starting at
the +SR point.  For example I have an image that is 1280x1024.  The render
had completed down to row 700.  I wanted to basically continue the trace but
starting back at line 450.  If  I use +c +SR450 the trace starts at 700.  If
I leave out the +c then the upper portion (1 to 449) is left out.

My main reason for not simply starting over is the amount of time the render
requires (4 days.)

I found a sloppy way of doing what I want by opening the BMP within a paint
program and copying the blank/black area below the image back up into the
rendered area.  (I noticed this area was all black with a thin line of color
on the far left side) Then using the +c it is starting back at 450 as I
wished.  I just though there must be an easier way to request a +c AND
+sr450 that would re-render (overwrite) from that starting point even though
the image was actually past that point.

Correct. Make a back up file of the original partially started render, and
render a new image with Start_Row set to make it start where you want.
Afterwards, take some sort of editor (MS Paint will do in a pinch) and
combine the two images.

It's a little sloppy, but admittedly POV-Ray's power is in what it can do
rather than how easy it is to do it.
