Read the file 'COPYING' for more information 0N/A * The ISO page sizes in the table below differ from ghostscript's idea of page sizes (by 0N/A * less than 1pt). Being off by <1pt should be OK for most purposes, but may cause fuzziness 0N/A * (antialiasing) problems when printing to 72dpi or 144dpi printers or bitmap files due to 0N/A * postscript's different coordinate system (y=0 meaning bottom of page in postscript and top 0N/A * of page in SVG). I haven't looked into whether this does in fact cause fuzziness, I merely 0N/A * will also affect whether fuzziness occurs. 0N/A * The remainder of this comment discusses the origin of the numbers used for ISO page sizes in 0N/A * this table and in ghostscript. 0N/A * The versions here, in mm, are the official sizes according to 0N/A * at 2005-01-25. (The ISO entries in the below table 0N/A * were produced mechanically from the table on that page.) 0N/A * (The rule seems to be that A0, B0, ..., D0. sizes are rounded to the nearest number of mm 0N/A * from the "theoretical size" (i.e. 1000 * sqrt(2) or pow(2.0, .25) or the like), whereas 0N/A * going from e.g. A0 to A1 always take the floor of halving -- which by chance coincides 0N/A * exactly with flooring the "theoretical size" for n != 0 instead of the rounding to nearest 0N/A * Ghostscript paper sizes are given in gs_statd.ps according to gs(1). gs_statd.ps always 0N/A * uses an integer number of pt: sometimes gs_statd.ps rounds to nearest (e.g. a1), sometimes 0N/A * floors (e.g. a10), sometimes ceils (e.g. a8). 0N/A * I'm not sure how ghostscript's gs_statd.ps was calculated: it isn't just rounding the 0N/A * "theoretical size" of each page to pt (see a0), nor is it rounding the a0 size times an 0N/A * appropriate power of two (see a1). Possibly it was prepared manually, with a human applying 0N/A * inconsistent rounding rules when converting from mm to pt. 0N/A * Should we include the JIS B series (used in Japan) 0N/A * (JIS B0 is sometimes called JB0, and similarly for JB1 etc)? 0N/A * Should we exclude B7--B10 and A7--10 to make the list smaller ? 0N/A * Should we include any of the ISO C, D and E series (see below) ? 0N/A#
