------- Additional comments from [EMAIL PROTECTED] Thu Feb 9 02:08:08 -0800 2006 ------- When importing Scalar Vector Graphics files (see: http://wiki.services.openoffice.org/wiki/SVG_User_Experiences) we have found that OpenOffice rounds graphics coordinates to the nearest 0.01mm. When importing absolute co-ordinate values this has little effect. However when importing x- and y-increments the total rounding error can add up. For example a time series plot of 1000 regulary spaced points (see above http page) was found to produce a plotting error of almost 5 mm! The SVG Import Filter has now been changed so that all increment arithmetic is done within the filter and only absolute coordinate values are passed to Open Office. However the same (as far as I know undocumented) problem will be faced by all other writers of graphics import filters. Can I request that OpenOffice graphics removes the constraint of always rounding to the nearest 0.01 mm. If this cannot be done in the general case - say in order to make it easier to identify identical/overlapping points - can I request that double precision arithmetic always be used when inputting a series of increments and that any conversion to 0.01 mm units only occurs after this stage.
