Lua Scripting - How to set antialiased value

[Anonymous]

I am trying to set antialiasing level in Netfabb through lua script, How to set that value. What syntax I can use

Hello, @Anonymous,

Welcome to the Netfabb forum!

This bit in the documentation is outdated, thank you for bringing this to our attention.

antialiased is not supported anymore. Instead, you must use the properties filtertype, filterradius, and filtersigma. Filter types are int from 0 to 4 for None, Gaussian, Oversampling, AntiAliased, and OversamplingEnhanced, respectively. filterradius is float in pixels. filtersigma is float and a sharpness value of sorts. The larger the value, the shallower the smoothing. Sensible values are between 0 and 10. filterradius and filtersigma are only used for Gaussian, filterradius is also used for OversamplingEnhanced. Oversampling halves the specified resolution when averaging, AntiAliased keeps the original resolution, and OversamplingEnhanced divides the original resolution by filterradius. AntiAliased has no parameters.

Best regards,

Steffen

Here's a working example script:

savepath = "c:\\luasliceimageexport";

system:logtofile(savepath .. "\\lualog.txt");
imageexporter = slice:createimagerenderer(slice.layercount, slice.layersize)

resolution = {};
resolution.x = 1280;
resolution.y = 1024;
size = {};
size.x = slice.maxx;
size.y = slice.maxy;
size.z = slice.maxz;

imageexporter.left = 0;
imageexporter.top = 0;
imageexporter.width = resolution.x;
imageexporter.height = resolution.y;
imageexporter.dpix = resolution.x * 25.4 / size.x;
imageexporter.dpiy = resolution.y * 25.4 / size.y;

imageexporter.minx = 0;
imageexporter.maxx = size.x;
imageexporter.miny = 0;
imageexporter.maxy = size.y;
imageexporter.minz = 0;
imageexporter.maxz = size.z;
imageexporter.writehatches = true;
imageexporter.fillclosedcontours = true;
imageexporter.dofillingbooled = true;
imageexporter.backgroundcolor = 0;
imageexporter.hatchcolor = 0xFFFFFF;
imageexporter.closedcontourcolor = 0xFFFFFF;
imageexporter.opencontourcolor = 0xFFFFFF;
imageexporter.fillpolygons = true;

function writetofile(tt, rr, ss)
    system:log("calling export with parameters tt " .. tt .. ", rr " .. rr .. ", ss " .. ss .. " ...");
    imageexporter.filtertype = tt;
    imageexporter.filterradius = rr;
    imageexporter.filtersigma = ss;
    imageexporter:exportpngmulticore (savepath .. "\\export-" .. tt .. "-" .. rr .. "-" .. ss ..".zip");
end;

writetofile(1, 1, 6.6);
