SVG animations

Recommended Posts

Hi Everyone,

 

Just dipping my toe into DrawSVG and I'm picking up on a project a previous developer has worked on.

Just got a couple of questions which I hope someone can help with.

 

In the html there is a long string of numbers, for example:

<path style="fill:#FFFFFF;" d="M-357.8,745.5v3.8c0,2,4.8,4.1,11.3,4.1s11.3-2.2,11.3-4.1v-3.8c-2.3,1.7-6.4,2.8-11.3,2.8
                                S-355.5,747.2-357.8,745.5z"
/>

 

Where does this get generated from? What is it doing? All the paths in the animation have these strings - some are very long.

 

Any help/clarification very gratefully recieved...!

Hi icraig6666  :)

 

Welcome to the forums. 

 

Most of the time you won't need to worry about that string. It will be generated upon export by your vector software. Rather than go into a long explanation here, I think this link can help you:

 

https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/d

 

Also, the drawSVG plugin will need a stroke on the path to work its magic. 

 

Hopefully that helps a little bit.

 

Happy tweening and welcome aboard.

:)

Just have to say that I got a laugh out of your question. I remember when I first heard about SVG. "It's really easy to work with and is just like HTML." I then opened an SVG file and was horrified by what I saw. A string of numbers that filled my entire screen. Well I've never seen any HTML that looked like that!

 

Like PointC said, you don't need to worry about it if the SVG has already been created for you. But there's no harm in learning how it works. It is human readable, and makes more sense when it's formatted better...

<path d="M100,50 L100,150 L300,150" /> 

A letter is a drawing command, and the numbers are usually pairs of x,y coordinates. So that will draw a line between those 3 set of coordinates.

I just came across a pretty interesting demo. You can see the coordinates being updated as you move stuff around.

If you want to learn more about SVG, here's a good place to get started.
