Hello.
I have a problem with label rendering Mapserver, and I haven't been able
to find a solution myself.
I'm rendering point labels with GEOMTRANSFORM 'labelpoly' to get a frame
around the label. To get more labels to show, I have enabled LEADER so
that labels are more likely to be visible but farther away from the
point. However, when a label is moved away and attached with a LEADER,
then the frame around the label gets an offset both vertically and
horizontally. See the image
https://www.dropbox.com/s/hwbt370d8371oqw/labeloffset.png?dl=0 where the
bottom left label has a leader, but the green frame is moved a few
pixels down and to the right.
Is the combination of LEADER and GEOMTRANSFORM 'labelpoly' not
supported, or am I doing something wrong?
Here is a section of my mapfile for the relevant layer:
LABEL
WRAP "!"
ALIGN center
TEXT ('[name]' + "!D116.7 " + '[ident]')
MAXSCALEDENOM 2600064

END
END

I appreciate any assistance or comments.
Kind regards,
Stephen
