...and of course the symbol should scale properly with the font size, so the definition should be:
.char \(bs \X'ps: import ATandTlogo.ps 9 4 109 104 \\n[.ps]'\h'1m' If you want the symbol to be sized a bit differently, you can either scale this with the help of inline escapes: .char \(bs \\R'xx \\n[.ps]*7/10'\X'ps: import ATandTlogo.ps 9 4 109 104 \\n[xx]'\h'.7m' or you can lie about the bounding box of the graphic: .char \(bs \X'ps: import ATandTlogo.ps 9 4 139 134 \\n[.ps]'\h'.77m' The same goes for vertical positioning: .char \(bs \v'.2m'\X'ps: import ATandTlogo.ps 9 4 109 104 \\n[.ps]'\h'1m'\v'-.2m' or: .char \(bs \X'ps: import ATandTlogo.ps 9 24 109 124 \\n[.ps]'\h'1m' Combinations of scaling and positioning are of course also possible.
