Inkscape

How to I export as PNG vectors and text without anti-aliasing?

Asked by Carl Mikkelsen

I am using Inkscape (thank you for creating it) to make a depth pattern for a CNC machine. The smoothing of the vectors and text is causing problems with the process of creating the tool path.

Is it possible to NOT have smoothing or anti-aliasing be applied to export output?

As a mitigation step, I will try rendering at 3x the resolution, and doing a majority operation on the resulting pixels, picking at the value for the pixel the most common value in the 3x3 region.

This question applies to the Windows version.

I did not find a way to get anti-aliased images from Inkscape, but I solved my problem with a different tool.

The "render at higher resolution" didn't work for me, as the base resolution seemed to be 90 DPI, and I didn't find a way to increase that. The net effect was that increasing the output resolution gave me more blurring, and the majority operation would not work.

Instead, I convert Inkscape SVG files to PNG using the "convert" command of ImageMagick, specifying the "+antialias" option. Yes, there is a plus sign before "antialias", with TURNS OFF antialias processing. I add a scale parameter to scale the image from 90 DPI (which seems to be the intrinsic coordinate system of Inkscape) to the resolution I need.

I'm closing this question.
