| * Sweep-and-update Euclidean distance transform of an | |
| * image. Positive pixels are treated as object pixels, | |
| * zero or negative pixels are treated as background. | |
| * An attempt is made to treat antialiased edges correctly. | |
| * The input image must have pixels in the range [0,1], | |
| * and the antialiased image should be a box-filter | |
| * sampling of the ideal, crisp edge. |
| // Creating a node graph editor for Dear ImGui | |
| // Quick sample, not production code! | |
| // This is quick demo I crafted in a few hours in 2015 showcasing how to use Dear ImGui to create custom stuff, | |
| // which ended up feeding a thread full of better experiments. | |
| // See https://github.com/ocornut/imgui/issues/306 for details | |
| // Fast forward to 2023, see e.g. https://github.com/ocornut/imgui/wiki/Useful-Extensions#node-editors | |
| // Changelog | |
| // - v0.05 (2023-03): fixed for renamed api: AddBezierCurve()->AddBezierCubic(). |
