- OASIS files can be read as well now. The reader automatically
determines the kind of file. OASIS layer names are supported. Due to
the complexity of the OASIS specification, or more precisely the
effort required to test a reader for meeting the specification, OASIS
support currently is regarded to be in "beta" state.
- Layers can now be organized hierarchically. Layers can be grouped
which allows to control visibility and other properties for the group
as a whole. Layers can be removed from the layer view list or new
layer views can be created.
- The layout can be transformed (rotated, shifted, mirrored) now. This
transformation is specified in the layer panel as a part of the layer
source specification. An optional transformation can be applied per
layer or layer group. This way for example, different layouts can be
aligned over each other.
- Shape properties now are supported. Each shape may carry optional
properties that are read from GDS or OASIS files. A property selector
can be applied per layer view, so that a layer only shows these shapes
that match the given property selection.
- As an experimental feature, the inverse layout tree can be
visualised by allowing the minimum hierarchy level to go into the
negative range. The effect of this is, that a cell is shown in the
context of all of it's direct parents, if the first hierarchy level is
set to -1. If set to -2, the cell is shown in the context of all of
it's parents and grandparents and so on. Since there is no particular
optimiziation for this feature, performance may be poor, if a cell
must be painted in a huge number of contexts. In addition, the context
displayed does not participate in selection or ruler snapping.
