Yes. When the BMP is created, a 'magic number' is written to the start of each
line. The continue trace code uses that to determine if the line has been over-
written by the renderer yet.

So, if I actually just copy the image, do all kinds of different work,
then let POV-Ray use a given INI-File to check for the
copied image with a given scene-file, it will go on from there?

Coool. Way cool.

provided you are using the same height and width, yes.

...and remember to set the continue flag.

When I stop a slow render, I usually make a copy of the output file, 
just in case I should forget to set the +c option when I restart the 
render. It has happened.

I've just spotted that about a third of a line
is missing, probably somewhere around the
position of the second or third continue.

It seems that POV screwed it up, but I won't
complain on a 3200x2400 image. Just need to
retrace that missing line when everything is finished.

Just look at the statistics:
3200x2400 = 7.680.000 pixel
So, if 2400/3 = 800, that's a percentage of:

Hm. The calculator screwed up.
Somewhere way below 0.1%

Comparing that to Windows "Standard",
this POV-Ray is just plain futuristic stuff...

As Ib said, remember to make a safety copy of your partial image before 
starting every continued render.  I'll make his meaning even clearer.

Because if you actually do forget to put in the continue trace option 
when restarting... PoV-Ray will trash your partially-completed work and 
begin again from scratch.  And that is a grief you do not want to 
experience after hours or days of waiting. 

Here's hoping your gerbera survives ... you have designed a really suberb 
work!

Cheers,
    Brian.

Thank you very much!

Yes, the Gerbera did surive, and I did make a lot of copies...
So, let's see... 8x22MB=176 MB. Hm. A lot a space.

Yeah, I know, its stupid keep ALL copies, but I wanted
to be really REALLY sure. I'll be deleting the older ones
soon.

And the print looks magnificient! I think I'll do that more often
to spice up my room a little...

I've just had a couple of my latest traces printed at an online digital 
photo service. The results beats any laser or ink jet prints, I have yet 
seen. I think that would to your hires image justice.

I use a local supermarket, but I think they send it to a german lab: 
http://www.photoprintit.de

It is not even all that expensive: 2 euro for a 20x30 cm print.
