Adam,

Good question.  It seems that MapServer CGI always uses the main mapfile
IMAGETYPE setting for scalebars and legends as well.  While not currently
possible, I would like to see an IMAGETYPE attribute added to the SCALEBAR
and LEGEND objects so different formats or format options can be used with
them if so desired.

For the time being, while discouraged, the INTERLACE, TRANSPARENT and
IMAGEQUALITY keywords should continue to work on the legend, and scalebar
objects.  Internally it takes the primary selected output format for the
map,
and modifies the option flags if necessary.  But if you depend on this,
expect to run into problems in future versions.

Best regards,
