Dear Nina,
Thanks for your mail. The above solution will work if the same length
is to be used in one column and two column formats. I often have to use
different sizes, however. For example, while in two column mode I may
use 0.75\Columnwidth, I would like to use something larger for one
column mode, because, the above size is rather small in one column mode.
Of course, 0.75\linewidth will become rather large in one column format.
To explain further, to fit the question papers that I set into one page,
I use the two column format (I tried to send a sample question paper as
an attachment to this mail, but it did not go through - I am resending
this mail without the attachment, which I will send separately to your
personal mail). I keep the questions and answers together, so that I can
easily maintain them and reuse them, if necessary: an \eatans command
kills all the answers, \eatquest kills all the questions; if I comment
out both, questions and answers come in the output. Because answers
often involve long expressions, I use the one column format when answers
have to be compiled. While setting the question paper, I often choose
small sizes for the figures, because of the self imposed requirement
that the questions should fit in one page. I don't have page
restrictions while preparing the answers. At that time, I am more
concerned about aesthetics. Typically, I end up using a slightly larger
size.
To cut the story short, I guess that I cannot escape from using the
conditionals. This is a lot more flexible, because, I can use different
ratios for different figures.
Thanks again.
Kannan
