Flowchart again: How is font size calculated

Flowchart again: How is font size calculated

Hi again,

after processing the attached document I get three flow charts
where the cells as well as the fonts have different sizes.

Why is that so?

Groet

changing nx=5 to nx=4 in the second chart, the sizes seem to be the same in 
the three charts. But I don't know it this really solves your problem. I'd 
guess that it has to do something with scaling down. But I haven't looked 
into the sources. (Next year ;->)

Yes, it looks like it. The maxwidth key seems to act a bit like the
width option in \externalfigure. It looks as if it is best to define
width and height wrt the font size and maxwidth and maxheight wrt the 
text size.

right; we cannot scale a flow chart as a whole using normal scaling due to 
the fact that annotations [hyperlinks and so] are on a separate layer in 
pdf and don't scale at all, we need to downscale using a font switch. The 
maxwidth parameter controls this.

there are also (yet undocumented) provisions to split charts over more pages.
