I guess I need to try this. So I assume that the offsets work relative
to the rotated label and not the image X-Y axis. Cool, I just noticed
that you have MULTIPLE labels for a single layer. I didn't know you
could do that. ... I love mapserver!!!
Actually they are all seperate layers right now. Sorry about the confusion.

LABEL
ANGLE AUTO
POSITION LL
TEXT "[L_FROM]"
OFFSET 10 5 ## it's interesting that these numbers don't need to
be negative like I thought at first.
...
END
LABEL
ANGLE AUTO
POSITION UL
TEXT "[L_TO]"
OFFSET 10 5
...
END
LABEL
ANGLE AUTO
POSITION LR
TEXT "[R_FROM]"
OFFSET 10 5
...
END
LABEL
ANGLE AUTO
POSITION UR
TEXT "[R_TO]"
OFFSET 10 5
...
END

Hi Bob,
Would you post what you have done so far? I have wanted to do
something like this for a long while.
Have you, would you open a bug for an enhancement to mapserver to
better support this functionality?
You might be able to get this to work with two layers by:
LABEL
ANGLE AUTO
POSITION CC
TEXT "[L_FROM] [R_FROM]"
WRAP " "
...
END
Then you can vary the number of spaces between the two fields based
on the line thickness and then use the OFFSETs to get them
positioned on the line.
It would be nice if POSITION could take a percentage along the line
segment as the label point. So 0.0 would be the start of the line
and 1.0 would be the end of the line and the angle would be based on
which part of the polyline that the label point fell on.

All,
Ok, I got my addressing range labels too llok pretty good using
four Layers with seperate LABELITEMS and OFFSETS.
Now I need to figure out a way, if possible, to scale the OFFSET
values based on the overall length of the line.
Can I use a value, line length, and a percentage of line length to
use for the Offset values of the labels. Right now the labels are
situated for the most part near the center of the line. I would
like to puch the labels out to the ends of the lines for example,
or pull them in closer for longer and shorter line segments.
This is purely an exercise in readability right now, what I have
seems to be working great for the customer. Thanks for the
pointers I got last week.
