No, the all measurements in the StarOffice -> OpenOffice Draw/Impress legacy are derived from raster screen bitmap graphics which has maintained the text "print" centric practice and uses a smallest "Field_Unit" of twips for calculations of placement onto the canvas.
A twip (1/1440") --from Postscript 1/72" point-- is a screen independent value converted (and rounded) in calculating vertex placements as pixel dimensions. There are routines to convert measurement from twip to mm or inch--but they are equally imprecise for use in CAD. Meaning there is no history for vector based measurements (vertex, angles, radius, and distances) needed for CAD. What is provided is all geared to rendering bitmap onto a raster canvas--for resample to screen pixels. So, the "arbitrary" lack of precision is a function of the resampling to "fit" bitmap elements to pixels of a raster screen. wo Floating point precision of measurements remains much less significant than performance for rendering the twip derived document canvas. Yes there was a tradeoff, but an easy one to make. If you need the precision for CAD you want a program designed to handle vectors under the hood, not bitmaps--period! -- View this message in context: http://nabble.documentfoundation.org/precision-of-Draw-dimensions-3-place-tp4166689p4166777.html Sent from the Users mailing list archive at Nabble.com. -- To unsubscribe e-mail to: [email protected] Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
