Ok, I have tested only the PostScript behaviour. Let's see what I can
detected:
Paper size
==========
I'm European (spanish), so I use A4 paper, also, I have configured Guide to
the default margins. On the header I can read:
% Change above BoundingBox to '0 0 578 757' for A4 paper.
So, I have changed. But the chart is shown not centered in paper. I have
twaked with the /xoff /yoff and finally I have settled this header:
*****************************************************
%!PS-Adobe-3.0 EPSF-3.0
%%BoundingBox: 0 0 579 757
% PostScript file generated by Guide. Header data (including these comments)
% comes from 'header.ps'.
% Change above BoundingBox to '0 0 578 757' for A4 paper.
/xclip 6300 def
/yclip 4800 def
/xoff -350 def
/yoff 80 def
******************************************************
With this xoff and yoff I have the chart perfectly printed in the midle of
the page. As this two values aren't on the header, I should put them
manually on each ps file generated by guide. Why they aren't on the ps? AS
the PS are now EPS compilant there are any need for a marging!, you can put
the PS inside other document with the composition defined...
User defined data sets
======================
Now, the ishophotes and the labels of TDF objects are show but not the
simbol!. I have a TDF that define a circle of a fixed size arround each
object (the size is computed to make a 1o circle at level 5 charts). This
circle is drawn in blue. On the Postscript file the circles are barely
visible. Looking at the postscrip source, I have seen the following
fragment:
**********************************
stroke 0.86 setgray
6486 5803 moveto
5761 4857 lineto
5600 4736 lineto
5435 4647 lineto
5402 4643 lineto
5322 4662 lineto
5212 4715 lineto
5138 4773 lineto
5100 4818 lineto
6507 5825 lineto
6486 5803 lineto
closepath fill
5300 4380 225 circle
5089 4649 225 circle
5089 4649 225 circle
4575 4170 225 circle
4682 3029 225 circle
4408 4623 225 circle
************************************
The first lineto block are surely an isophote (untill closepath fill), and
as you can see, before the circle block there aren't any setgray, so they
are "stroked" on the last gray level.
If I turn off the isophote, the circles are perfetly visible and now the
code for them are:
*************************************
stroke 0 setgray
style0
5300 4380 225 circle
5089 4649 225 circle
5089 4649 225 circle
4575 4170 225 circle
4682 3029 225 circle
4408 4623 225 circle
4408 4623 225 circle
4144 3736 225 circle
**************************************
With a perfectly black pen.
Well, I hope that this help you to stabilize the Make Postcript behaviour,
as I consider this the best value_added to your wanderfull program! I use
this option very frecuently to make high quality electronic charts!.
