/*
|
|
|
|
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.
