Vara is a javascript library that can create text drawing animations
Include the library as follows
<script src="./src/vara.min.js" type="text/javascript"></script>new Vara("#element","font.json",[{
text:"Handwritten"
}],{
fontSize:46
});The first argument, #element is the container element for the SVG.
The font used is a specially created JSON file that contains the information needed to create the text. It is included by passing the URL of the font as the second argument. A few custom fonts are available in the Github repository, more will be added soon. Creation of custom fonts are explained here.
The third argument is an array of objects, where each object will represent a block of text to be drawn. The text to be drawn is passed as the text property.
The last argument is an object to provide the options like fontSize,color etc.
new Vara("#container","font.json",[
{
text:"Hello World", // String, text to be shown
fontSize:24, // Number, size of the text
strokeWidth:.5, // Width / Thickness of the stroke
color:"black", // Color of the text
id:"", // String or integer, for if animations are called manually or when using the get() method. Default is the index of the object.
duration:2000, // Number, Duration of the animation in milliseconds
textAlign:"left", // String, text align, accepted values are left,center,right
x:0, // Number, x coordinate of the text
y:0, // Number, y coordinate of the text
fromCurrentPosition:{ // Whether the x or y coordinate should be from its calculated position, ie the position if x or y coordinates were not applied
x:true, // Boolean
y:true, // Boolean
},
autoAnimation:true, // Boolean, Whether to animate the text automatically
queued:true, // Boolean, Whether the animation should be in a queue
delay:0, // Delay before the animation starts in milliseconds
letterSpacing:0 // Number, space between each character
}],{
// The options given below will be applicable to every text created,
// however they will not override the options set above.
// They will work as secondary options.
fontSize:24, // Number, size of the text
strokeWidth:.5, // Width / Thickness of the stroke
color:"black", // Color of the text
duration:2000, // Number, Duration of the animation in milliseconds
textAlign:"left", // String, text align, accepted values are left,center,right
autoAnimation:true, // Boolean, Whether to animate the text automatically
queued:true, // Boolean, Whether the animation should be in a queue
letterSpacing:0
}).ready(function)
Is used to execute a function when the font is loaded and the elements are created.
Any other method should be called inside the function
