svgs | svgs is a compatiblity layer between svg | Animation library

Here is a simple example using Quadratic Bezier curves:

This is a nontrivial problem in general.

It can be solved easily (little code) if you can accept rasterizing the shapes to pixels, perform the boolean operation there, and then vectorize back the result using marching squares + simplification.

Known algorithms to compute instead a somewhat exact* geometric result are quite complex and difficult to implement correctly while keeping them fast.

Clipper is an easy to use library to perform this kind of computation in C++, with ports to Javascript.

Please note that what is difficult is to correctly handle edge cases (e.g. when input lines are partially overlapping or vertices fall exactly on a line and when the result includes zero-area parts).

Code that only reasons about cases in which crossings are clear is a lot easier to write, but unfortunately can produce results that are macroscopically wrong when those edge cases do actually happen.

Floating point math is too unpredictable to be used for these computations... see for example https://hal.inria.fr/inria-00344310/document for a detailed discussion of the kind of issues that will be present when using floating point math for exact geometric computation.

Even a "simple" equation like the one that tells if three points are collinear, clock-wise or counter-clokwise behave crazily when computed with floating point math... (images from the paper)

(*) The coordinates of the intersection of two segments with integer coordinates cannot, in general, be represented exactly by double-precision numbers; thus the result will still be an approximation unless you use a numeric library with support for rationals.

This does the trick, a few lines of javascript. First, on page load, identify all SVG images and determine the current prefers-color-scheme theme. Then, detect when that theme changes and append a dynamic cachebreaker to those filenames, which forces SVGs to reload.

I raised this issue on React Native's repo:

https://github.com/facebook/react-native/issues/32251

They released a new RN version 0.66.0 on 2nd October, 2021. I have confirmed that tintColor works on this new version and closed this issue.

For anyone below RN 66 who has this issue with Image tintColor, you can upgrade to RN 66 for tintColor to work. If upgrading is not an option now, you can use react-native-fast-image until you can upgrade. Alternatively, you can use different-colored versions of your images or SVGs as suits your needs. If your tinted images are mostly icons, you can also use react-native-vector-icons.

You can try to make method in components/BaseCryptoIcon.vue:

Use :not(), MDN lists the following syntax as experimental

Thank you for sharing a demo in the comments. It looks like a regression, I reported it on the Highcharts Github issue channel where you can follow this thread: https://github.com/highcharts/highcharts/issues/16149

As a workaround you can use the last working version: https://jsfiddle.net/BlackLabel/aLx4o7u3/

The root issue here is that matter.js positions objects based on their center of mass rather than the origin of the coordinate system that your vertices are in, and it is clear that the origin of the coordinate system for you blob vertices is not its center of mass since all of your vertices are positive. You can calculate the center of mass for your blob and then use that offset before drawing:

It comes from webpack where it seems to be an open issue. The causes of that issue was identified and recently added to the proposals of the new release for webpack. It could arrive somewhere in 2022 as stated here Class Fields (Private instance methods and accessors

You could either get rid of that addon that fails with webpack or try some of the quick-fixes suggested like this one here
