Hi, I notice in ps/ps.map/paper.h that A0 is slightly different than other published values. Actually other values found on the 'net are all over the place.
In an effort to "do it right" I've recalculated them as follows, from the fundamental A0=1m^2; W:H = 1:sqrt(2) definition: size|width_mm|height_mm|width_inch|height_inch A0|840.90|1189.21|33.106|46.819 A1|594.60|840.90|23.410|33.106 A2|420.45|594.60|16.553|23.410 A3|297.30|420.45|11.705|16.553 A4|210.22|297.30|8.277|11.705 A5|148.65|210.22|5.852|8.277 A6|105.11|148.65|4.138|5.852 A7|74.33|105.11|2.926|4.138 A8|52.56|74.33|2.069|2.926 A9|37.16|52.56|1.463|2.069 A10|26.28|37.16|1.035|1.463 the Matlab (should work in GNU Octave) script to do that is attached. I notice these still don't line up exactly with the more trusted values I can find. Usually the error is minor rounding in the wrong direction on the least significant digit, or truncation. I assume cascading rounding or conversion errors are generally to blame. (width becomes length from the previous size, etc) I'm not too concerned if ps.map paper sizes end up being off < 1/72" (1pt), but as there is so much noise out there on this I though it would be nice to use trusted values. Before I commit the above values, does anyone see a problem in my script or know if the sizes are actually defined by ISO as "rounded" values in some unit, versus the mathematical approach that I've taken? any requests on what sizes we should include? currently for ISO sizes we only define A0-A4. link of interest: http://www.paperonweb.com/size.htm regards, Hamish
