In the "parameters" field (for fig2dev) of the dialog box where you set the filename you can set an "-m" scaling option - for instance, "-m 0.5" to halve its size.
Thanks, Mark. I had already tried that, but it does not work, i.e., the picture appears in DVI file with the original size. (Try to insert the same picture twice, one with "-m 0.5" and the other one without "-m 0.5"; you will see no difference.)
Scaling works fine, but there are some problems that needs workarounds:
1. Entering the scale option the first time you include a figure works, adding the scale
option later doesn't. This happens because lyx converts "file.fig" into "file.eps" and "file.pstex_t".
Lyx (1.3.4) erroneously believes this only has to be done once. The conversion is re-done
if you change "file.fig" from lyx, not if you change it outside lyx or change the parameter list.
Workaround: Delete "file.eps" and "file.pstex_t" after changing conversion parameters (such as
using -m 0.5) or after editing "file.fig" outside lyx. You will then get the size you want!
2. Including the same figure twice with different conversion parameters (i.e. different size)
does not work. This because lyx converts the first figure, then looks at the second figure
using the same file and notices that the .eps and the .pstex_t exists (made in the previous conversion)
and then believes the job is done and skips it. Not skipping it wouldn't help, because a re-conversion
would overwrite the files needed to display the first figure right.
Workaround: If you really need the same figure several times _with different size_,
make a copy (or a link) with a different filename. Then, two conversions happens
and you get .eps+.pstex_t files with different names (and different internal sizes).
Copy the file if you might want to change the figures independently of each other.
Make a link if you want only one figure for future editing, changing either the original
or the link later will then change both.
So, the magnification parameter works fine, when you know how to work around its quirks.
If you change figures a lot, consider having a cleanup script that removes .eps+.pstex_t files,
it is useful untilthe problem gets fixed in lyx.
Thanks, Helge. Your workarounds do work fine. I do not need (at least currently) to insert the same picture twice; I only mentioned that to show _more_ clearly that something was wrong.
