Installation and Basic usage

Using NPM

npm install vara --save

Or download and include the library as follows

<script src="./lib/vara.min.js" type="text/javascript"></script>
<!-- Or jsdelivr -->
<script src="https://cdn.jsdelivr.net/npm/[email protected]/lib/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.

Options

// https://cdn.jsdelivr.net/npm/[email protected]/fonts/fontdir/fontname.json
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
    /* Letter spacing can be a number or an object, if number, the spacing will be applied to every character.
    If object, each letter can be assigned a different spacing as follows,
    letterSpacing: {
        a: 4,
        j: -6,
        global: -1
    }
    The global property is used to set spacing of all other characters

Returns an object with properties characters and container.

characters is an array of svg g elements, each representing a letter and container is an svg g wrapping the text block. If an id was given to the text during creation, it should be given as the argument, otherwise use the index of the text block.

.draw(id)

Used to animate texts with autoAnimation:false.

If an id was given to the text during creation it should be given as the argument, otherwise use the index of the text block.

.animationEnd(function(i,o){})

Used to execute a function once animation ends, triggers every time a block of text is drawn. Has two arguments,

i - The id of the drawn text.

o - The object described in the get() method.

.playAll()

Introduced in v1.1.0
