Hi,

POV-Ray inserted this into the command line parameters, when I made an
area render with an image size of 8000x4500 pixels:
+sc0.248406 +sr0.444099 +ec0.441055 +er0.635475

I finished maybe a bit less than half of that area, had to stop. Now I
want to continue, but need to know, how the float numbers above compute
into row line numbers, because I have to alter "sr" consequently. Thanks.

The values specify the start and end in fractions of the screen size; so
e.g. if your image is 1920 by 1200 pixels in size and you specify
+sr0.25 +er0.75, POV-Ray will (or at least should, to the best of my
knowledge) render lines 300 to 899.

Why don't you just use the row numbers directly? That is way simpler to use...

Just change your command line to:
+sc0.248406 +sr0.444099 +ec0.441055 +er0.635475 +c

The render will proceed from where it stopped in the requested area.

Hi.

It is not that I was the one who decided to use float numbers. That was
done by POV-Ray, it is a POV feature: when pressing SHIFT while creating
the area in which to render (inside the render image), POV-Ray copies
then that data into the command line. But that data uses floats, not
line numbers. Well, it makes sense, as this allows you to get the same
area being rendered independently from selected screen size (inside the
QuickRes.ini).
