![]() ![]() Potrace is licensed under the GNU GPL version 2, which includes usage restrictions that I believe would not be acceptable to Serif, which means that they cannot simply obtain and modify the Potrace source code. "Open Source" does not mean "freely usable by anyone for any purpose." Open Source programs are provided with specific license terms attached to them, which place restrictions on how the source code can be used. I don't pay for Chrome, Firefox or Libre Office Writer.Neither for Wings 3D, and Blender Cycles allows me to deliver highly realistic renders. But among the options, the concept of free/commercial is not the key: Potrace/inkscape is as professional as most expensive options.Ībout generally free being bad.Nope. To the level of quality I demand from my own output, and as one gets to be fast with node drawing tools with experience, it typically proved always to be faster and healthier to trace by hand from scratch (depends on the source image, and what is the style target). When I have needed to deliver, I've anyways carried to perfection those few nodes remained, worked by hand. You can get almost a fully optimized shape from one go with the embedded potrace in Inkscape, once knowing the tricks, and just some smoothing later on, and some cleaning will get you a just average (considered super good for most people that request this feature) and usable result. All I can tell you is that reducing a lot the number of colors, to get the right silhouette, and then building per shadow/color large area (by different passes, then compositing, or other techniques) is very doable, together with doing it in certain specific mode, and per stages, if you need the internal color and a lot of details, or in much more simplified way if you just need the silhouettes. My personal opinion is that Inkscape is quite below AD, in general as a solution for professional design (but Inkscape is actually good, in good hands), but Potrace, and its implementation in Inskcape, has been clearly superior to Illustrator's (as you could refine better the settings) for many years, during my time at certain company. It varies, is more of a case by case situation. BTW, I've seen in the thread (and sadly, in others) mentioned several times stuff about free tools not being at the right level, etc. ![]()
