Getting Started

Install vue-easeljs

On the command line:

npm install vue-easeljs --save

In app.js:

Vue.use(require('vue-easeljs'));

What is vue-easeljs?

Vue-easeljs provides Vue.js with tools to draw on an HTML5 canvas.

Using an HTML5 canvas you can apply JavaScript to draw shapes, create generative art, import images and animations from files, and print text.

Everything you need for drawing to a canvas is available in the browser, but to really get creative, use a library built for the job.

Vue-easeljs is a wrapper to a great library called EaselJS, so you can use it in your Vue.js projects. This allows you to use data-driven programming to achieve art effects.

Tutorial

First, meet Gary (they/them).

Gary is a sprite. They live in an image called a sprite sheet with all their friends. But we're just going to use Gary today.

First we'll need a canvas:

// Gary.vue
<template>
    <easel-canvas
        style="background-color: grey"
        :width="400"
        :height="300"
    >
    </easel-canvas>
</template>

All of our other elements will go inside the canvas, which controls the boundaries of where we can work.

This canvas is 400px wide and 300px tall. We gave it a grey background so that it will stand out from the rest of the page.

Wait, don't leave, it gets better. Let's drop Gary into our grey void.

To do that, we're going to need to bring in Gary's sprite sheet:

// Gary.vue
<template>
    <easel-canvas
        style="background-color: grey"
        :width="400"
        :height="300"
    >
        <easel-sprite-sheet
            :images="['images/lastguardian-all.png']"
            :frames="{width:32, height:32}"
        >
        </easel-sprite-sheet>
    </easel-canvas>
</template>

There's no change yet, that's ok.

This step was to add an easel-sprite-sheet which holds information about the image we'll use for our sprites. We're using an image called lastguardian-all.png.

It's full of all the characters and positions we might want to use. We used the frames attribute to let the easel-sprite-sheet know that each position, or frame, is 32px wide and 32px tall.

We've got a sprite sheet, but we need a sprite element to use it with:

// Gary.vue
<template>
    <easel-canvas
        style="background-color: grey"
        :width="400"
        :height="300"
    >
        <easel-sprite-sheet
            :images="['images/lastguardian-all.png']"
            :frames="{width:32, height:32}"
            :animations="{walk: [214, 215]}"
        >
            <easel-sprite
                animation="walk"
                :x="200"
                :y="150"
            >
            </easel-sprite>
        </easel-sprite-sheet>
    </easel-canvas>
</template>

There's Gary. Look at them run!

Let's see how Gary works. First, notice that we added animations to the easel-sprite-sheet. The animation walk uses frames 214 and 215. If you count 214 frames from the top left corner of lastguardian-all.png, you'll see Gary in mid-stride facing right. At frame 215, they're in a standing position.

Next we added easel-sprite and the first attribute we gave it was animation="walk" to match the easel-sprite-sheet.

We also included x and y coordinates. Setting them to 200 and 150 put Gary in the middle of our 400 x 300 canvas.

Well, almost the middle...

Gary is slightly off center, because their coordinates identify the position of their top-left corner by default.

Let's get Gary centered. Oh and we need to slow them down:

// Gary.vue
<template>
    <easel-canvas
        style="background-color: grey"
        :width="400"
        :height="300"
    >
        <easel-sprite-sheet
            :images="['images/lastguardian-all.png']"
            :frames="{width:32, height:32}"
            :animations="{walk: [214, 215]}"
            :framerate="30"
        >
            <easel-sprite
                animation="walk"
                :x="200"
                :y="150"
                align="center-center"
            >
            </easel-sprite>
        </easel-sprite-sheet>
    </easel-canvas>
</template>

Bingo. By adding align="center-center" we ensured that Gary's center is now at the x-y coordinates.

When we added :framerate="30" to the easel-sprite-sheet Gary got a little more mellow.

But even mellow humans were not meant to live in a vacuum. Gary needs a place to visit.

// Gary.vue
<template>
    <easel-canvas
        style="background-color: grey"
        :width="400"
        :height="300"
    >
        <easel-bitmap
            image="images/gulfstream_park.jpg"
            x="200"
            y="150"
            align="center-center"
        >
        </easel-bitmap>

        <easel-sprite-sheet
            :images="['images/lastguardian-all.png']"
            :frames="{width:32, height:32}"
            :animations="{walk: [214, 215]}"
            :framerate="30"
        >
            <easel-sprite
                animation="walk"
                :x="200"
                :y="150"
                align="center-center"
            >
            </easel-sprite>
        </easel-sprite-sheet>
    </easel-canvas>
</template>

Great! Well... not great.

We've added an easel-bitmap with an image called gulfstream_park.jpg. We added it above Gary's code in the file so that it would show up behind Gary.

It's centered just like Gary is. But it's much too large.

The file is 946px tall, and our canvas is only 300px tall. Let's just use some inline math to scale it down.

// Gary.vue
<template>
    <easel-canvas
        style="background-color: grey"
        :width="400"
        :height="300"
    >
        <easel-bitmap
            image="images/gulfstream_park.jpg"
            x="200"
            y="150"
            align="center-center"
            :scale="300 / 946"
        >
        </easel-bitmap>

        <easel-sprite-sheet
            :images="['images/lastguardian-all.png']"
            :frames="{width:32, height:32}"
            :animations="{walk: [214, 215]}"
            :framerate="30"
        >
            <easel-sprite
                animation="walk"
                :x="200"
                :y="150"
                align="center-center"
            >
            </easel-sprite>
        </easel-sprite-sheet>
    </easel-canvas>
</template>

That looks better. We added :scale="300 / 946" to multiply the image's height. Down in this case, from 946 to 300.

But Gary is still struggling to get down from that tree.

// Gary.vue
<template>
    <easel-canvas
        style="background-color: grey"
        :width="400"
        :height="300"
    >
        <easel-bitmap
            image="images/gulfstream_park.jpg"
            x="200"
            y="150"
            align="center-center"
            :scale="300 / 946"
        >
        </easel-bitmap>

        <easel-sprite-sheet
            :images="['images/lastguardian-all.png']"
            :frames="{width:32, height:32}"
            :animations="{walk: [214, 215]}"
            :framerate="30"
        >
            <easel-sprite
                animation="walk"
                :x="200"
                :y="275"
                align="bottom-center"
            >
            </easel-sprite>
        </easel-sprite-sheet>
    </easel-canvas>
</template>

Yes! We've changed Gary's y to 275 (trial and error works fine here). We've also changed their align to "bottom-center". This way we can think of Gary's position in terms of "where their feet touch the ground". This helps a lot when we want to resize Gary using scale while keeping their feet in place.

Full-featured Gary

Check out this Live Demo using Gary to see more of what you can do with vue-easeljs. In it we change Gary's scale and position dynamically, add some text that follows Gary around using an easel-container, use attributes like flip, draw red and white circles on screen, listen for click events, use transparency, use anti-aliasing to retain the 8-bit look, and make Gary run around using Vue properties and a time out.

x	number	horizontal position based on the origin of the parent component.	Default: 0
y	number	vertical position based on the origin of the parent component.	Default: 0

Example:

    image="/images/awesome-background.jpg"
    :x="0"
    :y="0"
    :align="['left','top']"
>
</easel-bitmap>

See Live Demo

easel-canvas

Give the vue-easeljs components a place to live. The canvas has no visible pixels of its own.

Attributes:

Attribute	Values	Description	Required/Default
anti-alias	boolean	whether or not edges should be smoothed on scaled images.	Default: true
height	number	the pixel height of the canvas on the page.	Default: 300
width	number	the pixel width of the canvas on the page.	Default: 150
viewport-height	number	the pixel height of the canvas internally.	Default: equal to height
viewport-width	number	the pixel width of the canvas internally.	Default: equal to width

The width and height props control the size of the canvas element on the page.

The separate viewport-width and viewport-height props control the size of the canvas internally. For example, a canvas with width and height of 100 can fully show an element of width and height 50. But the same canvas with viewport-width and viewport-height set to 40 cannot fully show the same element.

The viewport-width and viewport-height props are a convenience feature, allowing a developer to specify subcomponents' pixel sizes at a set size regardless of the actual size of the canvas. Setting small viewport sizes will make elements inside appear larger and pixelated, but if those elements are then scaled down they will not be pixelated. They will regain their original size and pixelation.

Example:

<easel-canvas width="500" height="100">
    <easel-shape
        form="rect"
        :dimensions="[500,100]"
        :x="0"
        :y="0"
        fill="#CCCCFF"
    >
    </easel-shape>
    <easel-text
        text="This is so easy!"
        :x="250"
        :y="75"
        font="70px Calibri"
        color="white"
        :shadow="['#000088',3,2,3]"
        :align="['center', 'alphabetical']"
    >
    </easel-text>
</easel-canvas>

easel-sprite-sheet

Define image animations for use in a sprite.

Attributes:

Attribute	Values	Description	Required/Default
animations	object	defines names for animations. Each animation is a series of frames.	Required
framerate	number	the speed the animation should play at.	Required
frames	mixed	usually an object with format: {width: width, height: height}.	Required
images	array	relative or absolute URL's to image files.	Required

EaselJS provides a lot of options for defining sprite sheets, to allow you to format the images in whatever way suits you.

A sprite sheet is a single image with a set of images on it that will be used in rotation to show an animation.

The friendliest approach is to layout the images in a grid. For example, if a character requires 32x32 pixels to show, you might create a sprite sheet with 10 frames of the character in a 320x32 pixel image. Or a 32x320 image. Or a 160x64 image. Whatever the image size, EaselJS will figure it out based on the width and height you give it.

In that case the following definition will do nicely:

<easel-sprite-sheet
    :images="['/images/character.png']"
    :frames="{width: 32, height: 32}"
    ...
>

But sometimes frames have space between them or margins around them. In these cases, you'll need to specify more information.

In this example, there is space and margin between the frames.

<easel-sprite-sheet
    :images="['/images/lots-of-characters.png']"
    :frames="{width: 32, height: 32, spacing: 5, margin: 10}"
    ...
>

Other times, the frames are different sizes or are on different images.

In that case, this format will be required:

<easel-sprite-sheet
    :images="['/images/thomasChugging.png','/images/thomasBraking.png']"
    :frames="[
        // x, y, width, height, imageIndex
        [0, 0, 64, 32, 0],
        [0, 32, 64, 32, 0],
        ...
    ]"
    ...
>

Animations give names to a series of frames. The name is used in the easel-sprite component to determine what to show.

The value of an animation is a number, array, or object.

If the animation is just one frame, a number is appropriate.

If the animation is multiple frames laid out in order in the sprite sheet, then the array short form can be used. The first two values are the start and end of the animation. The third value is an optional next animation to begin when this one is done. The fourth is speed.

If the animation uses frames that are not in order, use an object with the field frames and the optional next and speed.

animations: {
    stand: 0,
    run: [1, 4, "stand"],
    fall: {
        frames: [5, 1, 0, 2],
    },
}

Example:

<easel-sprite-sheet
    :images="['images/lastguardian-all.png']"
    :frames="{width:32,height:32}"
    :animations="{
        stand: 7,
        walk: [6, 7],
        walkAndStand: [6, 7, 'stand'],
        confusion: {
            frames: [5, 1, 0, 2],
        },
    }"
    :framerate="4"
>
    <easel-sprite
        :x="32"
        :y="32"
        animation="walkAndStand"
    >
    </easel-sprite>
>
</easel-sprite-sheet>

    :x="250"
    :y="32"
    font="20px Arial"
    color="red"
>
</easel-text>

See Live Demo

Align attribute

All visible components can accept an align attribute. The align attribute defaults to 'top-left'.

The values refer to where the x, y coordinates should lie in reference to the rest of the object.

For example, if a 50x50 square shape is aligned at 'top-left', and its x and y are at 65, 70, then the square's top left point will be at 65, 70 and its bottom right point will be at 115, 120.

If the same square was aligned at 'bottom-right', then it's bottom right point would be at 65, 70 and its top left point would be at 15, 20.

The field can be either a string or an array.

As a string it is formatted as 'vertical-horizontal'.

As an array it is formatted as [vertical, horizontal].

Most components have these alignment options:

vertical: top, center, bottom
horizontal: left, center, right

The easel-text component has extra alignment options:

vertical: top, hanging, middle, alphabetic, ideographic, bottom
horizontal: start, end, left, right, center

These are described in the whatwg spec for HTML5 canvases. In cases of text with multiple lines, the horizontal alignment value applies to every line.

Note: For backwards compatibility, the horizontal and vertical parts of the string or array can be reversed. Future major versions will obsolete this option.

Cache attribute

The cache attribute is a boolean.

When caching is active, a rasterized version of the element is created in memory and used instead of the source material that the element uses. The element essentially becomes an EaselBitmap.

Many of an element's props will cause a cache refresh when they are changed.

The props alpha, flip, rotation, shadow, x, and y are applied to an element after caching and will not cause a cache refresh. However, if an element is part of a cached EaselContainer, changing those props on the child element will refresh the container's cache.

An animated sprite will refresh the rasterized image on each frame change.

And so a cached element should behave no differently from a non-cached element in most respects.

The difference is that caching has an impact on performance. In many cases it increases an element's speed, but if the cache needs to refresh often it can decrease speed.

Filters attribute

Filters process a visual element's pixels, applying adjustments after the element is rasterized and before it is rendered on canvas.

The filters attribute is an array of arrays. Each filter array consists of the name of a filter followed by parameters.

Several filters can be applied to the same element.

Supplying filters forces cache to be true.

Available filters

This library comes pre-built with several filters.

BlurFilter

Blur an element. Applies to shadows as well.

['BlurFilter', x, y, quality]

Parameter		Range	Default
x	horizontal bluriness	0 - Infinity	0
y	vertical bluriness	0 - Infinity	0
quality	the number of blur iterations	0 - Infinity	1

ColorFilter

Systematically change the coloring of an element. Applies before shadowing is done. Use inside a container to include shadow.

['ColorFilter', rX, gX, bX, aX, rO, gO, bO]

Parameter		Range	Default
rX	red multiplier	0 to 1	1
gX	green multiplier	0 to 1	1
bX	blue multiplier	0 to 1	1
aX	alpha multiplier	0 to 1	1
rO	red offset	-255 to 255	0
gO	green offset	-255 to 255	0
bO	blue offset	-255 to 255	0

ColorMatrixFilter

Adjust the brightness, contrast, saturation, and hue of an element.

['ColorMatrixFilter', brightness, contrast, saturation, hue]

Parameter		Range	Default
brightness	add to the brightness	-255 - 255	undefined - no change
contrast	add to the contrast	-100 - 100	undefined - no change
saturation	add to the saturation	-100 - 100	undefined - no change
hue	add to the hue	-180 - 180	undefined - no change

PixelStrokeFilter

Add a pixelated stroke around the element.

['PixelStrokeFilter', [r, g, b, a]]

Parameter		Range	Default
color	color of stroke as array of red, green, blue, alpha	array, values 0 - 255	[0, 0, 0, 255]

Not yet available

The underlying library EaselJS has two more filters -- AlphaMapFilter and AlphaMaskFilter -- that are not yet available, because their use requires complicated access to canvases. The idiom of this library is that you should never have to access a canvas. In the future this library should provide an <easel-mask> element to do masking, making those filters unnecessary.

Custom filters

Create new filters by registering a class with the VueEaseljs library at runtime using VueEaseljs.registerFilter.

See further documentation on Custom filters.

Example:

const VueEaseljs = require('vue-easeljs');

class MyFilter {

    constructor(value1, value2) {
        ...
    }

    adjustContext(ctx, x, y, width, height, targetCtx, targetX, targetY) {
        ...
    }
}

VueEaseljs.registerFilter('MyFilter', MyFilter);

Font attribute

The font attribute is a string that controls the family, size, and weight of text in an easel-text component.

The string is mostly compatible with the CSS font property with some changes.

In most cases it must include the font size and font family.

Example: "16px Garamond"

It can optionally include any of font style, font variant, font weight, and font stretch, in that order, before the font size.

Example: "italic small-caps bold 16px cursive"

Shadow attribute

All visible components can drop a shadow with an optional shadow attribute.

The field is formatted as [color, xOffset, yOffset, bluriness].

Shadow options:

color: HTML color
xOffset: number
yOffset: number
bluriness: number

Events

All visible components and the canvas itself emit Vue.js events with an event object.

Event	Fired when...
added	Fired when the component is added to its parent.
animationend	Fired when an animation completes. (easel-sprite only)
change	Fired when an animation changes. (easel-sprite only)
click	Fired when the component is clicked or tapped.
dblclick	Fired when the component is double-clicked or tapped.
mousedown	Fired when the component is clicked down.
mouseout	Fired when the mouse leaves a component's hit area.
mouseover	Fired when the mouse enters a component's hit area.
pressmove	Fired when the component is dragged.
pressup	Fired when the component is unclicked.
removed	Fired when the component is removed from its parent.
rollout	Fired when the mouse leaves a component's hit area.
rollover	Fired when the mouse enters a comopnent's hit area.
tick	Fired many times a second to keep the components in sync. Using this event can impact performance.

Modifiers such as .stop usually work with the events.

For performance reasons, the events are only emitted if a handler exists. They will not show up in the Vue.js devtools if no handler exists.

Developer Tips

Chrome/Chromium Users:

When developing locally, Chrome limits canvas access to local image files. They can be viewed but click events will error out unless Chrome is opened with the --allow-file-access-from-files flag. But be careful, since this flag opens your system up to some danger if the scripts you run on your page are untrustworthy. This is a limitation of canvas that applies to all canvas libraries.

All users:

When accessing image files from other hosts, CORS must be setup on the foreign host or else click events will error out. This is a limitation of canvas that applies to all canvas libraries.

The EaselJS documents can be helpful. They are essential if you intend to fork this repo and make pull requests.

Pending

These will be implemented in future releases:

Percentages
Pre-load images
Masks
Mouse cursors
Hit areas

There are no plans to implement these features that EaselJS provides, but pull requests are accepted:

BitmapText
Buttons
Complex Vector Paths
MovieClip
