I have code like this through svg one polygon is grey and another one is colored.
I need the effect like the colored gradient color should be animated so that it should feel like the water filling (waves) on the grey color logo.
for the colored polygon i given attribute display none.

This is pretty ugly code.
Here is Codepen example: https://codepen.io/trueweb/pen/OJLpLNB
I did something similar with CSS keyframes:
https://codepen.io/trueweb/pen/xxKZrBX
It looks like I cannot animate my rounded chart with keyframes

If you want to animate a stroke, you have to actually have a stroke, otherwise you're animating something that's not rendered.
svg {
width: 300px;
}
svg .line {
stroke: red;
stroke-dasharray: 1000;
stroke-dashoffset: 0;
animation: dash 13s linear;
}
#keyframes dash {
from {
stroke-dashoffset: 1000;
}
to {
stroke-dashoffset: 0;
}
}

Apply CSS on part of line element in SVG [duplicate]

This question already has an answer here:
line segmentation in D3.js
(1 answer)
Closed 6 years ago.
I am creating several horizontal and vertical lines and I want to paint a segment of the line say from point a to point b in some other color. I can to the same creting multiple lines but can it be done using some svg or d3 library where you can keep the same line and just paint a segment part of that line in different css?

You can use a gradient for the stroke

RMagick::Image.from_blob method don't work

I using Ruby, Sinatra and RMagick
I wont take browser icon (.svg file), add to icon text - version of browser - and return new .svg as respond to user
I wont open .svg as string, add some lines with my text and save this as new .svg file using RMagick.
but method to_blob and from_blob doesn't work correct
# myapp.rb
require 'sinatra'
require 'rmagick'
get '/test/:browser' do
img = Magick::Image::read("icons/default/#{params[:browser]}.svg")[0]
str = img.to_blob
"<textarea name='image' cols='100' rows='100'>#{str}</textarea>"
end
documentation from https://rmagick.github.io/image3.html#to_blob
img.to_blob [ { optional arguments } ]-> string
Description: Creates a Binary Large OBject, a direct-to-memory version
of the image.

What I doing wrong?
Or, if you have another idea how to do this task - please, share.

get '/test/:browser' do
image = File.open('icons/default/chrome.svg')
blob = image.read
"<textarea name='image' cols='100' rows='100'>#{blob}</textarea>"
end
This is what i need.
First open file, then use read method.
In this case all work correct and .to_blob not needed

Change color on mouse hover svg

I want to set a faint yellow color lighting effect (car head lights) to my svg element. It is possible to do this on mouse hovering?
Here is my car's svg element:

The SVG data you posted doesn't seem to do anything. However, you can use SVG filters to add glare effects. Here's an example:
svg:hover .headlight {
fill: yellow;
filter: url(#f1);
}
<svg width="600" height="300" viewBox="0 0 600 300">
<defs>
<filter id="f1" x="-25%" y="-25%" width="150%" height="150%">
<feGaussianBlur in="SourceGraphic" stdDeviation="15" result="glare" />
<feMerge>
<feMergeNode in="glare" />
<feMergeNode in="SourceGraphic" />
</feMerge>
</filter>
</defs>
<path fill="black" stroke="none" d="M0 0 600 0 600 300 0 300z" />
<circle cx="150" cy="150" r="50" fill="darkslategray" class="headlight" />
<circle cx="450" cy="150" r="50" fill="darkslategray" class="headlight" />

the animation is moving vertically but i want it be moved horizontally.
I am not able to do this . someone please help me out
My confusion is the gradient is like vertical. how can i set the stop tag with the offset for the different colors and animation.
and also in animate tag. if i use freeze instead of repeatcount attribute that will take full single color but i want it to filled with the gradient i.e how it animates.
Better if the animation come like the waves from the bottom to top.(liquid filling effect)
JSfiddle
Added the svg code for the final image i needed after the animation
<?xml version="1.0" encoding="utf-8"?>
js fiddle updated
the animation movement to be from bottom to top and gradient color should be from left to right .and also i need that to be animated like the water waves

You mean like this? I've just used y2 instead of x2
