<br>
I am sure this must have been asked before, but was not able to find<br>
anything in the mailing list archives or wiki...<br>
<br>
Our survey is going to be published in a magazine. The magazine has very<br>
strict limits on the survey size; 28 cm x 18 cm max, with limits on line<br>
thickness as well. Making the final PDF survey the right size is done<br>
with the layout "scale" definition, but this means I need to very<br>
carefully (painfully) recalculate it whenever an extension changes the<br>
size of the survey.<br>
<br>
Main question; Is there a way to make Therion automatically calculate<br>
the correct scale to fit certain dimensions?<br>
<br>
(I do understand that this might be impossible, since the output can<br>
change based on the scale, so it would become an iterative process. I am<br>
just hoping there might be some magic.)<br>
<br>
<aside><br>
<br>
For those interested, I have used code metapost to set the line<br>
thicknesses so that they work according to the minimum line thickness:<br>
<br>
def minimumpen = 0.18pt enddef;<br>
def PenA = pencircle scaled (minimumpen*1/0.35) enddef;<br>
def PenB = pencircle scaled (minimumpen*0.7/0.35) enddef;<br>
def PenC = pencircle scaled (minimumpen*0.5/0.35) enddef;<br>
def PenD = pencircle scaled (minimumpen) enddef;<br>
def PenX = pencircle scaled (minimumpen*1.2/0.35) enddef;<br>
<br>
</aside><br>
<br>
Thanks for any assistance.<br>
<br>
