Dear list, On my LyX 1.2.1 display, my EPS images are converted to bitmaps with one or more pixel widths shaved off the right edge. Try this for yourself, draw a hollow box with xfig and transfig it to EPS. From my experiences, I would expect it to draw in LyX with its right edge missing. Some rounding-off error I expect, should round the width _up_ one pixel, not down. Otherwise the edge objects are cropped.
Hope it helps (and is reproducible =) Have fun, Darren
