Switching between 2 values in an SVG animate element - animation

I want to switch between exactly two values in an SVG animate element. I tried it this way:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="150" height="150" viewBox="0 0 150 150">
<rect x="10" y="10" width="100" height="100" fill="blue" stroke="red">
<animate attributeName="fill-opacity" values="0; 1" dur="1s" repeatCount="indefinite"/>
</rect>
</svg>
I wanted have the fill-opacity switching between the values 0 and 1. But what it does is fading from 0 to 1. I want it to stay on 0 for 1s, then stay on 1 for 1s, back to 0 for 1s and so on.
How do I do that? I tried nearly all possible attribute combinations but didn't manage it.


You want calcMode="discrete" on the animate element the default is linear.

SVG Animation puts back after completed [duplicate]

This question already has an answer here:
XML SVG - persist the end state of an animation
(1 answer)
Closed 1 year ago.
I just made a simple SVG animation using the tag "animate" inside the SVG tag group. It works nicely BUT right after the animation is completed, it goes back to the beginning, to the initial frame, then stops.
How should I modify my code inside the animate tag in order to keep the animation still in the last frame?
Thanks,

How should I modify my code inside the animate tag in order to keep
the animation still in the last frame?
To achieve this use the fill =" freeze " attribute
Below is an example without using fill =" freeze "
As in your description - the figure returns to its original state
<svg id="svg1" version="1.1" xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink" width="400" height="200" viewBox="0 0 400 200" style="border:1px solid gray;" >
<circle cx="30" cy="100" r="30" fill="purple" >
<animate attributeName="cx" begin="svg1.click" dur="3s" values="30;300" />
</circle>
</svg>
Second example using fill =" freeze "
After the animation ends, the shape will remain in the last frame of the animation.
<svg id="svg1" version="1.1" xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink" width="400" height="200" viewBox="0 0 400 200" style="border:1px solid gray;" >
<circle cx="30" cy="100" r="30" fill="purple" >
<animate attributeName="cx" begin="svg1.click" dur="3s" values="30;300" fill="freeze" />
</circle>
</svg>

Why my image positioning in svg has an offset of 22?

I try to position an image inside a svg graphics to the left border, but with x=0 the image has a offset of 22. When x=-22 it fits, but why?
This is my svg:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="400px" height="200px" version="1.1" xmlns="http://www.w3.org/2000/svg">
<image x="0" y="50" width="200px" height="100px" href="data:image/png;base64,__base64data__" />
</svg>
And here is the result:
When I reduce x to -22 it looks fine, but it should be 0, shouldn't it?
<image x="-22" y="50" ...
How can I fix it? Where does the margin comes from?
Thanks a lot.

SVG: include image with color attribute

I'm trying to load an SVG image into an other SVG image. This works pretty well. However, I can't seem to change the color of the loaded/embedded image from the main file.
In the w3 specs (https://www.w3.org/TR/SVG/struct.html#ImageElement) it says I could use the presentation attribute color.
Here is what I have, the main svg is generated by PHP (so I can easily use dynamic colors & dynamic included images):

I've searched on SO and the rest of the internet, and see some other ways to add color to the image element, like style="fill:#ff9900" or style="color:#ff9900" but they don't seem to work.
Hoping someone can point me into the right direction.

SVG strange behavior in IE10+

I'm using svg patterns to define custom background images for the fill attribute in svg's later in the page. I'm hiding the original svg and pattern definitions at the top of the page.
IE9 has no issues
IE10 doesn't show anything
IE11 working in fiddle, but in production only shows last one on page
Here is a stripped down example: http://jsfiddle.net/CCFWj/3/

The Microsoft SVG deviations are vague on the subject of the pattern element:
The display property affects pattern elements and references to those pattern elements
On the subject of xml:space:
The xml:space attribute is not supported in SVG.
So xml:space and pattern deviations may cause no side-effects in one version of IE, but several side-effects in another.

svg clip image and show stroke

Hi I am new on this site so please forgive me if i am not clear about what i am trying to do
My Question is:-
I am using HTML5 and SVG to clip the image so that only the part of the image that is inside the clipping/polygon shape is displayed while any part outside the polygon shape is invisible/clipped
Also I wish to add stroke width and color to the polygon shape
The SVG code that i am using:-

The above mentioned code works fine, it display's an image that has a polygon shape, only the image part falling inside the shape is displayed whereas any part falling outside the shape is hidden
But somehow I tried various things but still i am not able to display stroke/border.
My question is how to display the border/stroke on a polygon shape that is used to clip an image
Thanks in advance

At first, please write ID in small letters in order to make the clip path work: <clipPath id="SVGID_1_">
Second, just duplicate your path in order to use is as regular shape.

Alternatively, you can define you path as a shape and just refer to its name afterwards:

Check out this doc.

Here you are using an image from within the SVG but if suppose you are using clip path on the image in your html code, you won't be able to give it border this way.
To achieve that you can apply the clip-path to the container div of the image too and then give it a background and border of the same color.
