    It allows users to create tasks, change their schedule and duration with drag-and-drop, add dependency lines, and review extra information on tasks via tooltips. You can add multiple timescales to the chart. The list of possible options includes Quarter Day, Half Day, Full Day, Week, and Month. There are also some customization opportunities such as changing the tooltip content with custom HTML, modifying the appearance of task bars and dependency lines, and setting the default timescale. It should be noted that Frappe Gantt has two dependencies: momentjs and snapsvg.

    In my research to solve the CSS animation issue I branched out and one of my findings was SVGs (Scalable Vector Graphics). Having already gained some proficiency with Adobe Illustrator in my previous career, I’m going to experiment and create some SVG’s soon, perhaps for some buttons or landing page graphics. The low file size and clarity of the graphics is really appealing, and I think they could make my future portfolio really pop! The SVG Snap library looks interesting.

    Learning Fabric

    Enter fullscreen mode Exit fullscreen mode

    Next, we initiate a Canvas instance in our script tag:

    Syntax

    new fabric.Canvas(element: HTMLElement|String, options: Object)
    
    Enter fullscreen mode Exit fullscreen mode

    This allows Fabric.js to create this class instance so that we can use the provided methods of Fabric.js:

    const canvas = new fabric.Canvas("canvas", {})
    
    Enter fullscreen mode Exit fullscreen mode

    Now, we’ll go ahead and give our canvas different properties, such as width, height, and background color:

    const canvas = new fabric.Canvas("canvas", {
     width:500,
     height:500,
     backgroundColor:green
    })
    
    Enter fullscreen mode Exit fullscreen mode

    Output

    Creating a Rectangle with Fabric.js

    Now that we’ve initialized a canvas and given it various properties, we’re going to create a rectangle using the Fabric.js object fabric.Rect:

    Syntax

    new fabric.Rect({object})
    
    Enter fullscreen mode Exit fullscreen mode

    Here the object houses the rectangle properties:

    const canvas = new fabric.Canvas("canvas", {
     width:500,
     height:500,
     backgroundColor:green
    });
    
    const rectangle = new fabric.Rect({
     width:200,
     height:200,
     /* fill is used to define the background color*/
        fill:'red'
    })
    /*the add method is used to add objects to the canvas element */
    canvas.add(rectangle)
    /*the renderAll method used to render the canvas*/
    canvas.renderAll();
    
    Enter fullscreen mode Exit fullscreen mode

    The add() method is used to add objects to the Canvas element. In this case, it adds the rectangle we created to the canvas:

    Output

    Creating a Circle

    In the same way, we’ll create a circle. This time, we’ll use fabric.Circle:

    const canvas = new fabric.Canvas("canvas", {
     width:500,
     height:500,
     backgroundColor:"lightgray"
    });
    
    const circle = new fabric.Circle({
     radius:60,
     fill:"blue"
    })
    canvas.add(circle);
    canvas.renderALl();
    
    Enter fullscreen mode Exit fullscreen mode

    Output

    With the above steps, we created a rectangle and a circle using Fabric.js. Note how interactive the objects are! Next, we’ll discuss images in Fabric.js.

    Images with Fabric

    The Fabric.Image is a Fabric.js object used to render images on a canvas. With Fabric.js, we can interact with the image. Images can be added to our canvas in two ways:

    • Fabric.Image
    • Fabric.Image.fromURL

    Using the Fabric.Image constructor requires us to create an image element in our HTML and then insert it into the constructor:

    Syntax

    fabric.Image(image_element)
    
    Enter fullscreen mode Exit fullscreen mode

    HTML

    
    
    
    
    Enter fullscreen mode Exit fullscreen mode

    JS

    const image_element = document.querySelector('#image');
    const image = new fabric.Image(image_element)
    canvas.add(image);
    canvas.renderAll();
    
    Enter fullscreen mode Exit fullscreen mode

    However, Fabric.Image.fromURL requires only the image URL (the URL can be retrieved from a website or your local folder), and is simpler than the former:

    fabric.Image.fromURL(URL, function());
    
    Enter fullscreen mode Exit fullscreen mode

    After passing the URL, the callback function after the image is loaded. The first default parameter of the callback function is the fabric.Image object. Now, we can modify the image properties and then add it to the canvas:

    const canvas = new fabric.Canvas("canvas", {
     width:500,
     height:500,
     backgroundColor:"White"
    });
    
    fabric.Image.fromURL('my_image.png',(img) => {
     // the scaleToHeight property is use to set the image height
        img.scaleToHeight(250)
     // scaleToWidth is use to set the image width
        img.scaleToWidth(250)
        canvas.add(img)  
    })
    canvas.renderAll()
    
    Enter fullscreen mode Exit fullscreen mode

    Output

    Editing Images with Fabric.js

    Now that we know how to insert an image into a canvas, we’ll look at other image objects like image filters.

    Image Filters

    Fabric.js provides us with built-in filters:

    • BaseFilter
    • Brightness
    • convolute
    • GradientTransparency
    • Grayscale
    • Invert
    • Mask
    • Noise
    • Pixelate
    • RemoveWhite
    • Sepia
    • Sepia2
    • Tint

    Every instance of fabric.Image has the "filters" property, which is a simple array of filters. We can use the array method to perform any required operation, including removing filters (pop, slice, shift), adding filters (push, unshift, slice), and even combining multiple filters. When we call applyFilters, any filter in the “filters” array will be applied one by one. Let’s use some of these filters:

    Syntax

    new fabric.Image.filters
    // after that you can add any filter of your choice
    // Example 
    new fabric.Image.filters.Grayscale()
    
    Enter fullscreen mode Exit fullscreen mode
    fabric.Image.fromURL('my_image.png', (image) => {
          image.scaleToHeight(300)
           image.ScaleToWidth(300)
    
     // Creating filter
     const filter = new fabric.Image.filters.Grayscale()
    
     //push the filter instance to filters
            image.filter.push(filter)
    
     // apply filter
             image.applyFilters()
    
     //add image into canvas (it also re-render the canvas)
             canvas.add(image)
    },{crossOrigin: 'anonymous'});
    canvas.renderAll();
    
    Enter fullscreen mode Exit fullscreen mode

    Output

    Above, we used the Grayscale filter; we can also apply other filters. All we have to do is simply change the filter, as shown in this example:

    fabric.Image.fromURL('my_image.png', (image) => {
          image.scaleToHeight(300)
           image.ScaleToWidth(300)
    
     // creating filter
     const filter = new fabric.Image.filters.Sepia()
    
     //add filter
            image.filter.push(filter)
    
     // apply filter
             image.applyFilters()
    
     //add image into canvas (it also re-render the canvas)
             canvas.add(image)
    },{crossOrigin: 'anonymous'});
    canvas.renderAll();
    
    Enter fullscreen mode Exit fullscreen mode

    Output

    Image Blending

    Blending is mixing two or more images to create a new image. Fabric.js gives us this ability. Here, we’re going to use the image blending filter for our image:

    Syntax

    new fabric.Image.filters.BlendImage({
     // the image that we want to blend
              image:imageA,
     // blend mode (in this case we are using the 'add' mode)
              mode:'add',
    
     alpha:0.5
          });
    
    Enter fullscreen mode Exit fullscreen mode
    fabric.Image.fromURL('my_image.png', (imageA) => {
        imageA.scaleToWidth(350)
        imageA.scaleToHeight(350)
        canvas.add(imageA)
    
     // Blending filter
        filter = new fabric.Image.filters.BlendImage({
     image:imageA,
     mode:'add',
     alpha:0.5
          });
    
     //Add the second image  
         fabric.Image.fromURL('my_image2.png',(imageB) => {
               imageB.scaleToHeight(100),
                imageB.scaleToWidth(100),
                canvas.add(imageB)
           }, {crossOrigin:''});
    
         imageA.filters.push(filter);
         imageA.applyFilters(canvas.renderAll.bind(canvas));
    },{crossOrigin:''})
    
    Enter fullscreen mode Exit fullscreen mode

    Output

    Image Clipping

    A very popular effect used today is image clipping, or rather image cropping, which is done to remove parts of an image that we don’t want. With Fabric.js, we can achieve this by using the clipPath method.

    First, we have to create our own clipPath using any Fabric.js object. Then, we’ll assign it to the clipPath property of the object we want to clip. Here, we’ll use a circle object:

    const clipPath = new fabric.Circle({
     radius:150,
     top:200,
     left:250,
     // The originY and originX helps to center the image and the clipPath
        originY:"center",
     originX:"center"
    })
    
    Enter fullscreen mode Exit fullscreen mode

    After that, we add it to the image that we want to clip using the filter method:

    new fabric.Image.fromURL('my_image.png',(img) => {
      img.scaleToHeight(300)
      img.scaleToWidth(300)
     // positioning the image
      img.scale(o.5).set({top:50,left:100})
     // Clip Path
      clipPath = new fabric.Circle({
     radius:150,
     top:200,
     left:250,
     originY:"center",
     originX:"center"
        })
      canvas.add(img)
      canvas.clipPath = clipPath;
      });
    canvas.renderAll();
    
    Enter fullscreen mode Exit fullscreen mode

    Output

    Image Blurring

    Like other image filters, the blur filter accepts objects because they can be adjusted. A practical example is changing the brightness of an image. You can apply other image filters without any additional configurations (like grayscale, invert, or sepia). Other image filters like brightness, pixelate, tint, and noise all operate in this way, too. However, the difference is that their values are not the same. The brightness filter's actual brightness level ranges from-1 (full black) to 1 (full white). The noise filter's value is between 0 and 1000. For the blur filter, the value ranges from 0 to 10.

    Syntax

    new fabric.Image.filters.Blur(object)
    
    Enter fullscreen mode Exit fullscreen mode
    fabric.Image.fromURL('my_image.png', (image) => {
          image.scaleToHeight(300)
           image.ScaleToWidth(300)
    
     // Creating the blur filter
     const filter = new fabric.Image.filters.Blur({
     blur:0.6
           })
    
     //push the filter instance to filters
            image.filter.push(filter)
             image.applyFilters()
             canvas.add(image)
    },{crossOrigin: 'anonymous'});
    canvas.renderAll();
    
    Enter fullscreen mode Exit fullscreen mode

    Output

    Conclusion

    In conclusion, Fabric.js gives us an awesome experience when working with Canvas. It also provides a lot of features, some of which we covered in this article. For full details on some of the Fabric.js objects, you can review its documentation here.
