Meshlabserver filter reference won't export.

[Nik Willmore]

Windows 10, 64 bit, fresh Meshlab installation, the manual for filters is hiding in the program itself, so I can't read it, as the:

meshlabserver -d Filters.txt

command crashes Meshlabserver with:

Loading Plugins:
Current Plugins Dir is: C:/Program Files/MeshLab/plugins
Total 241 filtering actions
Total 12 io plugins
called here!

It also seems very odd that it can output a filters log file (blank text file at first), but that it wan't me to create my own blank text file to open and write to?! I did that and that's when the crash happens instead a file not found error. I made the tile with Notepad and then closed Notepad. The crash spits out a Windows error box about Meshlabserver has stopped working. I tried moving Filters.txt out of the Meshlab folder onto my C: drive and it didn't help, so is unlikely a permissions thing, nor did running Cmd.exe as Administrator help. Whether the GUI program was running or not didn't matter.

The -d flag is described rather oddly too:

"-d filename dump on a text file a list of all the filtering functions"

Dump on?! Why not normal English descriptions of commands and why not just spit out a text file instead of need to open an existing one? Better yet, why not just generate the text file and include it in the directory for me to read? This is very disappointing after being so excited about good triangular remeshing being callable from Python so easily.

When the Windows crash error happens I was able to assign Visual Studio as my debugger and it gave this error:

Unhandled exception at 0x00007FFB64F58378 (filter_layer.dll) in meshlabserver.exe: 0xC0000005: Access violation reading location 0x00000000000000A8.

I can use the -i flag to successfully load an STL file.

Could someone just post the manual here?

Next, if I create and export a two step script in the GUI, to do Iso Parameterization remeshing, a script that runs fine in the GUI., meshlabserver.exe fails with a memory error on my 24GB PC opening a 566KB mesh file. It doesn't matter if the GUI is running or not either.

The error is similar with the beta version of Meshlab, but the memory error is gone:
