Matthias Koefferlein 277ab2c335 Refactoring of GDS2 writer - split large functions into smaller ones 2024-07-30 00:13:47 +02:00

Matthias Koefferlein b7e2b59852 First implementation of GDS2 coordinate overflow checks. 2024-07-29 19:54:29 +02:00
Matthias Koefferlein 0dd6fca51e Implemented a fix for #1794 (giant meta info produces invalid GDS) 
This fix solves two problems:
* Too large meta info data
* Too many meta info entries

The first problem is fixed by splitting the strings that serialize
the meta info.

The second problem is fixed by introducing prefixed strings that
indicate the attribute index within the string, not inside
the PROPATTR record.

The solution is backward compatible, although old versions will
not read all meta info and skip entries that exceed the GDS
capacity.

Caveat: the produced GDS files may contain duplicate PROPATTR
keys. This is not strictly illegal, but some third-party processors
may drop such entries.

Matthias Koefferlein 999c065262 Introducing iterated arrays for instances 
Iterated instances are created for OASIS files
using irregular repetitions in viewer mode.

Reason: this way, the same drawing optimization
than for iterated shape arrays can be applied.

As this is a new API feature, some adjustments
had to be made to incorporate them into the
code.
