svg-path | Manipulate SVG path data | Animation library

I want to know how to properly use vuetify components that itself use icons with @mdi/js.

My vuetify config looks like this:

I want to dynamically draw/turn an SVG with React from degree paramters that im recieving. Its like the direction arrow from a weather-info.

1. How do I dynamically draw an SVG in Javascript / ReactJS?
2. How do I turn the SVG with variable input?

I'm aware, that you can draw SVG-Graphics like this:

I have an svg path as below

I have multiple png files and I'm trying to get the polygon contour coordinates. That is the simplified coordinates, only each outer corner (not a convex hull polygon).

The program that will do this at the moment is python and opencv. But another program is oke I did try to fix this using npm packages, imagemagick, potrace, Lua. It will be uses as a shell command in a 'build polygons from images' process.

This was the last test under python.

The problem now is the that some edges are 'not' correct in the example below.

I did the following steps

• Convert the alpha to black and white
• Trace the contour
• Get the coordinates

1. The original png file contains black lines (keep them).

1. Converted black and white image (you can't see the top line, because this website have a white background)

I'm working on a script to reverse the draw direction of SVG path commands, everything is working smoothly so far but not with S path commands or T.

In one of my implementations for path reverse functionality based only on cubic bezier C curves, works flawlessly, however the output path string is considerably larger, sometimes double or triple the length.

Here's a simplified version of the reversePath.js which, so far, implements some basic handling for S and a test page:

I stucked a little.

I have a code that is working in codepen and if I paste it in opened F12 window it will work fine, so it is ok.

The idea of this svg code was that I can hover not exactly on path, but somewhere near, for it to change color.

But I need to generate exact same code using javascipt, I wrote 2 classes, used them, they now generate same code as in codepen link, I can see it in F12 dev window, but it doesn't work.

My javascript code:

There are relatively straightforward ways of accomplishing this in vanilla Javascript (see this for one such approach), but I'm struggling getting something like this to work in React, particularly with an animation library like Framer Motion.

Framer Motion's useViewPortScroll returns a handy scrollYProgress object whose "current" property tells you what percentage down the page the user is currently scrolled.

I'd like to use this property to do something like this: const pts = path.getPointAtLength(scrollPercentage * pathLength);, and then use pts.x and pts.y for the x and y attributes of, say, a circle SVG - so every time I scroll down (or up) the page, the position of the circle would update/animate along the SVG path.

I'm struggling getting this to work with React's more declarative style, as I'd have to use refs for both the circle and the path elements, meaning I would have to place the aforementioned pts = path.getPointAtLength... code inside of a useEffect call, with both refs as dependencies (or else the refs would be undefined, in which case the pts.x and pts.y properties on x and y of my circle SVG would be inaccessible on first render.

Has anyone solved a similar problem or could possibly provide guidance?

i am trying to draw a SVG objects similar to pie chart using the SVG path element. I had earlier used the example from this stackoverflow post to generate the SVG arc path. But somehow my two arc which are supposed be part of same circle dont form a full circle. here is the code example i used to generate my arcs on a circle.

I want to resize a contour such that it fills to the size of its enclosing container. This post seems to say that I need to give the SVG a viewBox in order for it to know how to properly display the contour. If that is the appropriate course of action, how can I change other elements (such as axes) so they keep an appropriate size.

My current attempt is below which creates a contour out of a 50x50 array at threshold 0.
