This can result in considerably smaller PDF output files. See Vector Devices https://ghostscript.readthedocs.io/en/latest/VectorDevices.html for more details. * Ghostscript/pdfwrite now supports passing through PDF "Optional Content". only the question rises if -dCompatibilityLevel=1.4 is given why does ghostscript with its pdfwrite engine does show the messages about WriteObjStms and WriteXRefStm ... Could be a bug in ghostscript pdfwrite engine -- You are receiving this mail because: You are on the CC list for the bug.
