[Therion] point:passage-height

[Dave Clucas]

I've just tried this again and it's fine so I must have been doing something 
wrong.

The definition is in file thpoint.cxx from line 959

  if (postprocess) {
this->point->export_mp(out);
double scl = 1.0;
switch (this->scale) {
  case TT_2DOBJ_SCALE_L:
scl = 1.414;
break;
  case TT_2DOBJ_SCALE_XL:
scl = 2.0;
break;
  case TT_2DOBJ_SCALE_S:
scl = 0.707;
break;
  case TT_2DOBJ_SCALE_XS:
scl = 0.5;
break;

So the scales are: 2.0, 1.414, 1.0, 0.707, 0.5 

Try to change them and compile therion. without any guaranty ;)

It looks the xs s and m scale are not enough differenced - see attachment

hi bruce,

passage-height goes with modes 2, 3, 4, and 5

dave might redefine the mpost macros scaling the label (lab) in a custom layout.

Dave
The key to modifying the symbol definition
may lie in the file thText.mp in the sources
 
Ie Here is the code from 5.3.9 as an
example
 
vardef p_label@#(expr txt,pos,rot,mode) =
  if (mode=1) or (mode=7): interim
labeloffset:=(u/8) fi;
  lab:=thelabel@#(txt, pos);
  if mode>1: pickup PenD fi;
  if mode=1:
    pickup pencircle scaled
(u/6);
    drawdot(pos);
    process_label(pos,0);
  elseif mode=2:
process_uplabel;       
  elseif mode=3: process_downlabel;
  elseif mode=4: process_updownlabel;
  elseif mode=5:
process_circledlabel;
  elseif mode=6: process_boxedlabel;
  elseif mode=7:
process_label(pos,rot);  % station name
  elseif mode=8:
process_filledlabel(pos, rot);
  else: process_label(pos,rot); fi;
enddef;
 
I have not looked into how it works, but I’m
guessing the ‘point height’ and ‘point passage-height’
labels are one of the ‘modes’ above, and that the processes called
are default metapost routines.  Too complicated for me to unravel.
 
BTW shouldn’t you be using ‘point
height’ to indicate the height of cobble banks, rather than ‘point
passage-height’? (Probably the same symbol size issue will apply).
 
Also, as a path to a possible work around,
I think the AUT symbol set includes the option to label ‘line pit’
(or is it ‘line wall:pit’)?  I have never managed to get it to
work – but have not tried too hard either.

Footleg - I'm not using the symbol to control the passage height, I'm
using it to show the depth of a trench in a gravel bank.
Vasily - I'm already using base-scale to control the size of other symbols
but this one is too big. I need to make it smaller without changing all the
symbols. The size is probably related to the font size but again I'm happy with
the font size for labels etc, I just want to change this particular symbol.

base-scale command in layout maybe helps you

E.g.

scale 1 2000
base-scale 1 500

[Therion] point:passage-height

[Dave Clucas]

I'm using point passage-height to show the depth of some cobble banks. The map 
scale is 1:2000. The symbol almost fills the passage which is 9m wide and I 
can't find a way to scale it down. Using -scale xs makes no difference and I 
can't find any definition for the point or any metapost code to change it. I 
tried the layoutScales from Bruce but that made no difference.

Does anybody know how I can modify it?

[Footleg]

I just have the following line in my layout:

symbol-hide point passage-height

That way I can use passage height points to control the heights of
passages in my model, but they do not get rendered on the survey as
symbols at all.
