2) Change from legacy Cu stack to counting down from top=(F_Cu or 0). The old Cu stack required knowing the count of Cu layers to make sense of the layer number when converting to many exported file types. The new Cu stack is more commonly used, although ours still gives B_Cu a fixed number. 3) Introduce class LSET and enum LAYER_ID. 4) Change *.kicad_pcb file format version to 4 from 3. 5) Change fixed names Inner1_Cu-Inner14_Cu to In1_Cu-In30_Cu and their meanings are typically flipped. 6) Moved the #define LAYER_N_* stuff into legacy_plugin.cpp where they can die a quiet death, and switch to enum LAYER_ID symbols throughout. 7) Removed the LEGACY_PLUGIN::Save() and FootprintSave() functions. You will need to convert to the format immediately, *.kicad_pcb and *.kicad_mod (=pretty) since legacy format was never going to know about 32 Cu layers and additional technical layers and the reversed Cu stack.

The largest distance that wx can support is INT_MAX, since it represents
|
|
distance often in a wxCoord or wxSize. As a scalar, a distance is always
|
|
positive. On most machines which run KiCad, int is 32 bits and INT_MAX is
|
|
2147483647. The most difficult distance for a virtual (world) cartesian
|
|
space is the hypotenuse, or diagonal measurement at a 45 degree angle. This
|
|
puts the most stress on the distance magnitude within the bounded virtual
|
|
space. So if we allow this distance to be our constraint of <= INT_MAX, this
|
|
constraint then propagates to the maximum distance in X and in Y that can be
|
|
supported on each axis. Remember that the hypotenuse of a 1x1 square is
|
|
sqrt( 1x1 + 1x1 ) = sqrt(2) = 1.41421356.
|
|
|
|
hypotenuse of any square = sqrt(2) * deltaX;
|
|
|
|
Let maximum supported hypotenuse be INT_MAX, then:
|
|
|
|
MAX_AXIS = INT_MAX / sqrt(2) = 2147483647 / 1.41421356 = 1518500251
|
|
|
|
This maximum distance is imposed by wxWidgets, not by KiCad. The imposition
|
|
comes in the form of the data structures used in the graphics API at the
|
|
wxDC level. Obviously when we are not interacting with wx we can use double
|
|
to compute distances larger than this. For example the computation of the
|
|
total length of a net, can and should be done in double, since it might
|
|
actually be longer than a single diagonal line.
|
|
|
|
The next choice is what to use for internal units (IU), sometimes called
|
|
world units. If nanometers, then the virtual space must be limited to
|
|
about 1.5 x 1.5 meters square. This is 1518500251 divided by 1e9 nm/meter.
|
|
|
|
The maximum zoom factor then depends on the client window size. If we ask
|
|
wx to handle something outside INT_MIN to INT_MAX, there are unreported
|
|
problems in the non-Debug build because wxRound() goes silent.
|
|
|
|
Let:
|
|
const double MAX_AXIS = 1518500251;
|
|
|
|
Then a maximum zoom factor for a screen of 1920 pixels wide is
|
|
1518500251 / 1920 = 790885.
|
|
|
|
The largest ZOOM_FACTOR in above table is ZOOM_FACTOR( 300 ), which computes
|
|
out to 762000 just below 790885.
