Thanks Stacho
I think you are pointing me in the
direction of answering my second question; redefinition of each type of point
that I might be interested in. ie p_sink, p_doline, p_entrance.
(Admittedly I have not delved into the
code to see how it currently works, and I should perhaps educate myself some
more before asking.)
Some of my points would have all three (or
more) flags set (sink, doline, entrance). Are they just layered one above
the other in the output? So there may be three copies of the (identical) text
layered one above the other if each definition included printing of the text?
When I have time I can look into the TMPDIR outputs and perhaps figure it out.
Anyway I digress. My most pressing
need and interest is (the first question in my original post) adding the text
output to fixed points that do not have any other flags set. The
ones that show up in
Thanks

fixed points
Well, it is quite
complicated, but it is possible. When point symbol is exported from centerline,
system _text attribute is set in metapost. To dipsplay label, use code
code metapost
def p_continuation(expr pos,theta,sc,al) =
etc...

But you will need to redefine corresponding symbol (e.g. p_sink). In that code,
you can also control, whether symbol and/or text should be displayed. Feel free
to ask more, if this does not help you.

Hi
All
I’ve
been trying to understand symbol-show and symbol-hide a little better as they
relate to pdf outputs. How do I display the text associated with fixed
points?
I
have some map objects defined for various caves in a large system. These
are comprised of scrap drawings.
I
also have a map object with the minor surface features nearby, such as sinks,
dolines, isolated entrances and significant navigational features such as fence
posts or trees (for example). This is comprised of a survey only (mostly fixed
points, and no scrap drawings) however and uses flags such as doline or sink,
and most points have a text string associated ie.
fix
15 2521640
6042938
581 10 10 30
station
15 "Concrete water trough"
I
would like to show the caves as outlines with all the rest of their symbology
turned off, and the surface features with each of the points labelled with
appropriate symbol and associated text. This is for an area map, at
scales of say 1:5000 or 1:10,000
I
can turn the cave symbols off with symbol-hide statements, and so far I think
that is working out OK.
However…
-layout-symbol-show point
flag:entrance \
-layout-symbol-show point flag:sink \
-layout-symbol-show point flag:spring \
-layout-symbol-show point flag:doline \
-layout-symbol-show point flag:dig
\
The
above layout statements cause the special entrance and sink etc symbols to be
displayed, AND show the text string associated with the point. These are
not displayed by default as far as I can tell, but these statements rectify
that.
-layout-symbol-show group all
And
the group all statement has pretty much the same effect in a more comprehensive
and compact format.
However
none of the above enables me to display the text for my “Concrete water
trough” example above.
It
is always just a cross with no text, or with ‘15’ if debug
station-names is on. It shows up in
So,
how do I display the text associated with fixed points?
Is
there a need for…
-layout-symbol-show point fixed
…
or something similar?
Also,
sometimes I would like to display the point symbols (for the likes of the above
flags) OR the text strings associated with the points, but not both at
once. Is there a way of doing this?
Thanks
Bruce
