I tried both pdftops and pdf2ps to convert a pdf figure(no text) into eps. pdf2ps created a ps figure same to the original one, but the ps file produced by pdftops contains an extra white padding/margin surrounding the original figure. Is it normal for pdftops ? If so, does that mean I have to crop the extra padding/margin every time after I use pdftops ?
remark: pdftops generates a smaller file(about half size) than pdf2ps.
