Re: [Kicad-developers] "Multichannel signed distance field" font rendering
Michael, Thank you very much for your work on the MSDF text rendering, it is an significant improvement to the previous algorithm. I have just pushed your changes to the master branch.

Re: [Kicad-developers] "Multichannel signed distance field" font rendering
Hello all! Thank you very much for the feedback. As I understand the technique works well enough on many different hardware levels (I'm using it myself in an i5 iGPU), so that's good to know. I tweaked the character placement to get in accordance with what the truetype font specifies. Beside other issues, this fixes the reported GND baseline problem, still their bounding boxes are not bottom-aligned, but their baselines are. These changes were pushed to the sdf branch. There are some issues left that I would call minor (some special chars show slight glitches), but I would think that should not be a showstopper for now, I will still eventually try to address them. So unless there are important issues left I would polish the codestyle and get in touch with Orson for inclusion? The atlas tool is now available on Github with CMake support (thank you very much José!), so there should be no "blackbox"-problem remaining. Cheers!

Hey, thanks for noticing. That and more off by one errors I'm working on to fix currently. As I said, not polished, rather proof-of-concept.

Re: [Kicad-developers] "Multichannel signed distance field" font rendering
Hi, I just committed some basic CMake support to that repo, it should compile on all platforms provided you have the freetype and boost libraries installed (I don't know which minimum versions are required). It compiled successfully on Debian stretch with boost 1.61 and freetype 2.6.3.

Hello Jean-Pierre, Could you tell us more about this command-line tool? the tool uses the MSDF-library by Viktor Chlumsky, adds a rectangle bin packing algorithm (max rectangles global) to pack the texture atlas and outputs in the format that is used by KiCad currently. Given that, for full support (Better character placement, maybe even kerning?) I would like to cooperate with Orson to make the necessary changes to the current OpenGL string code. I uploaded the Visual Studio project for the tool under MIT-License (the library by Viktor Chlumsky uses that license) to https://github.com/decimad/msdf-atlasgen . Cheers!

It works great on my end! As for the tool, I think it would be good to just have it in a repo on github, as it could be very useful for other projects too.
