Hallo Erich, i have try to use some symbols created by the java tool. Some symbols be fine, but some does not work. Becaus Kicad has a more complex slotting function. The slotting function from kicad has to be splittet in to several files for= use in geda, if there is a way in geda, to use multible symbols with one footprint and o= ne refdes. what you think? regards smilie Am Mon, 1 Feb 2021 11:04:23 +1030 schrieb Erich Heinzle <a1039181@gmail.com>: > The calculation is simple if the file format is well documented, indicati= ng > how the origin for a symbol's transformations is specified. >=20 > It may be that no translations are needed beyond that associated with the > x,y location on the schematic, prior to and/or after application of the > rotation, but as i said, some refactoring will be needed, to allow a symb= ol > and it's elements to be rotated correctly. >=20 > Regards, >=20 > Erich >=20 > On Mon, 1 Feb 2021 07:56 smilie, <smilie@posteo.de> wrote: >=20 > > Hello Erich, > > > > I just saw it. > > The rotation matrix A, B, C, D. > > There is a discussion in the forum about it. > > But the calculation seems simple. > > > > | A B | > > | C D | > > > > then corresponds to a simplified rotation: > > 0 =C2=B0, 90 =C2=B0, 180 =C2=B0, 270 =C2=B0 > > or mirrored > > 0 =C2=B0, 90 =C2=B0, 180 =C2=B0, 270 =C2=B0 > > > > look here: > > > > https://forum.kicad.info/t/unit-orientation-mirror-matrix-explained/783= 9/2 > > https://de.wikipedia.org/wiki/Drehmatrix > > > > > > Matrix multiplication is just: > > > > x '=3D x * A - y * B > > y '=3D x * C + y * D > > > > or so. > > The difficulty is to turn every element with it. > > > > Regards, > > smilie > > > > > > > > > > Am Fri, 29 Jan 2021 22:00:46 +1030 > > schrieb Erich Heinzle <a1039181@gmail.com>: > > =20 > > > I implemented kicad eeschema symbol/lib -> gschem symbol conversion, = but > > > decided that I would need to refactor to allow eeschema schematic > > > conversion. > > > > > > I may give it a go at some point.
