Hi Wayne-
The new file format looks awesome. Very simple and readable. Would it be possible to standardize the transformation data? Currently there seems to be a couple different formats, some examples: (draw line (pts xy(76.581 47.9425) xy(77.724 47.9425)) (layer 21) (width 0.127)) (size 1.016 1.651) (at -1.524 0) (at (xyz 0 0 0)) (scale (xyz 0.17 0.16 0.16)) (rotate (xyz 0 0 0)) I think having a standard format would be very helpful for external utilities reading/writing kicad data, like: (object (position xyz(1, 1, 1)) (rotation xyz(0, 0, 0)) (scale xyz(1, 1, 1)) ) Or if you want shorter names, you could use the p/r/s letters for position/rotation/scale or t/s/r for translation/rotation/scale and v3 for a 3d vector: (object (t v3(1, 1, 1)) (r v3(0, 0, 0)) (s v3(1, 1, 1)) ) Although nowadays storage is usually not an issue, and the file can be optionally compressed with zlib. So probably the more verbose names are better. One of the small boards I saved was 28k in the old format, 52k with s-expr, 6k s-expr compressed. Another alternative would be a 3x3 matrix: (object (transform matrix(1, 1, 1, 0, 0, 0, 1, 1, 1)) ) Thanks- -lajos On Sat, Apr 7, 2012 at 2:58 PM, Miguel Angel Ajo Pelayo <[email protected]> wrote: > nice!!!, I will start trying it. > > > 2012/4/7 Wayne Stambaugh <[email protected]> >> >> Oops!
