This subclass always returns the same bounding box.
The bounding box that this helper always returns.
Compute an approximation of the bounding box obtained by applying transform_xy to the box delimited by (x1, y1, x2, y2)
.
The intended use is to have (x1, y1, x2, y2)
in axes coordinates, and have transform_xy be the transform from axes coordinates to data coordinates; this method then returns the range of data coordinates that span the actual axes.
The computation is done by sampling nx * ny
equispaced points in the (x1, y1, x2, y2)
box and finding the resulting points with extremal coordinates; then adding some padding to take into account the finite sampling.
As each sampling step covers a relative range of 1/nx or 1/ny, the padding is computed by expanding the span covered by the extremal coordinates by these fractions.
