how to control contour label position ?


I am generating contour plots and I am using the "levels" and "c_annotation"
parameters. However because I need to superimpose other objects over the
contour plot, I need to move the labels from where IDL is placing them. 
A better description would be to "slide" them along the contour, to places
where they will not conflict with the other elements in the plot.

I am not asking for an automatic way, but I would imagine there might be
a variable that measures length along a contour. For that matter, how
does IDL decide where  to place each label on its contour?

Thanks for any help!
