Hi, I have a problem, I’m trying to add to my sript a function that reads a lzo compressed data. Unfortunately, i don’t know very well C++ and i don’t know how to use the library into maxscript.
Someone can help me ?
You can use this in your maxscript if I’m correct. (.net).
http://lzo-net.sourceforge.net/
I cannot help you with the dotnet stuff – since I do not use it myself.
But I figured this would be a easier way then to implement it in c++ and then expose to maxscript as plugin function.
max2011 test:
dotnet.loadAssembly @“C:\Documents and Settings\User\Desktop\lzonet_1.0.1\lib\lzo.dll”
– Runtime error: dotNet runtime exception: Invalid directory on URL.
this mean that i must re-compiled dll with max SDK… but i don’t know how do…
uhmm… but this work:
lzo = dotnet.loadAssembly @“C:\Documents and Settings\User\Desktop\lzonet_1.0.1\lib\Simplicit.Net.Lzo.dll”
showProperties lzo
showMethods lzo

according to the docs, what you need is the LZOCompressor class:
lzocompressor = lzo.createInstance "LZOCompressor"
compressedByteArray = lzocompressor.compress yourByteArray
thanks, i never used dotnet in maxscript. But don’t work, it return undefined
i found in Visual Studio project the class what i must instanced “public class LZOCompressor {…”
but lzocompressor = undefined…???
i recompiled in Framework 2.0 3.0 3.5 but the same issue … i’m confused
sorry, you also need to include the namespace
lzocompressor = lzo.createInstance "Simplicit.Net.LZO.LZOCompressor"
compressedByteArray = lzocompressor.compress yourByteArray
ok, now load but how work the dll ? i write
>lzo = dotnet.loadAssembly “D:\Documents and Settings\Admin\Desktop\lzonet_1.0.1\lib\Simplicit.Net.Lzo.dll”
>lzocompressor = lzo.createInstance “Simplicit.Net.Lzo.LZOCompressor”
>compressedByteArray = lzocompressor.compress #()
and return
>#(17, 0, 0, 0, 0, 0, 0)
but if i write
>compressedByteArray = lzocompressor.compress #(1,2,3,4)
write a strange error…
… uhm… i must use Encoding.Default.GetBytes ?
(dotnetclass "system.text.encoding").default.getbytes "my string"
