Add Zmx samples

Actual behavior

When I try to import some 3rd-party *.zmx-files — nothing happen:

• https://github.com/ARSYkun/LSKM
• https://github.com/jegudmunds/refractor_designs

In same time when I try to import LSST_Baseline_Design_Spiders_Baffles.ZMX — Astree show me "Unable to Open Zmx file:"

• https://github.com/lsst-se/LSSTOpticalDesign

Expected behavior

• Add few samples in Zmx-format;
• Add some checks on after "Import Zmx file..." and if format is unsupported:
  • Show warning message window with some extra info (file name, format version, etc.);
  • Post warning message in terminal output.
• Add some docs about supported file formats.

Just found repo with Zmx files in supported format:

• https://github.com/luosaiyu/ZEMAX

Zmx files in this repo has next header:

issue is related to glass catalog, need to inspect and load all .agf file in a portable manner, trying glob() for now

[edeforas]

the non-readable files are encoded in UTF16 format, need to detect and convert...

need to inspect and load all .agf file in a portable manner

Thanks. There are some *.agf samples on GitHub:

• https://github.com/heterophyllus/glassplotter/tree/master/AGF
• https://github.com/nzhagen/zemaxglass/tree/master/AGF_files

the non-readable files are encoded in UTF16 format, need to detect and convert...

Just tried to import Hubble.zmx example — nothing happen in Astree.

I looked inside Hubble.zmx using text editor: its encoding is set to UTF-16LE (with BOM) + line endings mode is set to CRLF (Windows).

If change encoding to UTF-8 (without BOM) + leave line endings mode as CRLF (Windows) — Astree show error/warning message: "Unable to Open Zmx file!!:".

BUT if change encoding to UTF-8 (without BOM) + set line endings mode to LF (Unix) — Astree could import it!

Another one testcase:

• https://github.com/tim-balloon/tim-inst_modl/tree/master/optical_design

There are two Zmx files: CassTele.zmx and ForwardModel.zmx. Both files encoding set to UTF-8 (without BOM) + line endings mode set to LF (Unix).

Astree could import CassTele.zmx file.

BUT if try to import ForwardModel.zmx — Astree could NOT import it and show warning message: "Unable to Open Zmx file!!:"
