Sylwester, >From the link you sent it looks like you also make use of the internal plP_mmpcx and plP_gphy functions. Really what you want is the string width, or even a box around the string, returned in physical coordinates rather than mm? This would then only require a single new API call? We may be add in a API function if you can convince us it is useful. Before doing so we would need to make sure we designed a proper and generally useful external interface rather than just making the existing private functions available.
