Suggested March 2024 How To Set The Border Colour Of Image In Fabricjs?

In this tutorial, we are going to learn how to set the border colour of Image in FabricJS. We can create an Image object by creating an instance of fabric.Image. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to set the border colour of Image, we use the borderColor property.

Syntax Parameters

element − This parameter accepts HTMLImageElement, HTMLCanvasElement, HTMLVideoElement or String which denotes the image element. The String should be a URL and would be loaded as an image.

options (optional) − This parameter is an Object which provides additional customizations to our object. Using this parameter origin, stroke width and a lot of other properties can be changed related to the image object of which borderColor is a property.

callback (optional) − This parameter is a function which is to be called after eventual filters are applied.

Options Keys

borderColor − This property accepts a String which specifies the colour of the border when our image object is selected. Its default value is rgb(178,204,255).

Passing borderColor key with a String value Example

Let’s see a code example of how we can assign a value to the borderColor property. We have assigned the value “red” to the borderColor key which helps to create the red border on selection of our image object.

}

)

;

;

Passing a rgba value to the borderColor key Example

Instead of passing simple colour names as a String, we can also use RGBA values, whose components specify the amount of Red, Green, Blue and Alpha, where alpha denotes the opacity. In this example we have used rgba(164,0, 0,1) which is the rgb value for the colour dark red.

You can select the image object to see the border colour added using rgba value

How To Draw A Hexagon With Polyline Class Using Fabricjs?

We can create a Polyline object by creating an instance of fabric.Polyline. A polyline object can be characterised by a set of connected straight-line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. A hexagon is a closed two-dimensional polygon with six sides.

Syntax new fabric.Polyline(points: Array, options: Object) Parameters

points − This parameter accepts an Array which denotes the array of points that make up the polyline object.

options (optional) − This parameter is an Object which provides additional customizations to our object. Using this parameter origin, stroke width and a lot of other properties can be changed related to the Polyline object.

Example 1: Creating an Instance of fabric.Polyline() and Adding it to our Canvas

Before creating a start, let’s see a code example of how we can add a polyline object to our canvas. The only required parameter is the points Array whereas the second argument is the optional options object.

var canvas = new fabric.Canvas(“canvas”); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(250);

var points = [ { x: 30, y: 50 }, { x: 0, y: 0 }, { x: 60, y: 0 }, ];

var polyline = new fabric.Polyline(points, { left: 100, top: 40, fill: “white”, strokeWidth: 4, stroke: “teal”, });

canvas.add(polyline);

Example 2: Creating a hexagon with Polyline

In this example, we will create a hexagon using the Polyline instance. We can select the coordinates in such a way that the shape forms a hexagon as given below.

var canvas = new fabric.Canvas(“canvas”); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(250);

var points = [ { x: 50, y: 0 }, { x: 25, y: 43.30}, { x: -25, y: 43.301 }, { x: -50, y: 0}, { x: -25, y: -43.301}, { x: 25, y: -43.301 }, { x: 50, y: 0 }, ];

var polyline = new fabric.Polyline(points);

polyline.set(“stroke”, “teal”); polyline.set(“strokeWidth”, 3); polyline.set(“fill”, “white”); polyline.set(“top”, 50); polyline.set(“left”, 100); polyline.set(“scaleX”, 0.75); polyline.set(“scaleY”, 0.75);

canvas.add(polyline);

How To Draw A Rectangle With Polygon Object Using Fabricjs?

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc.

Syntax new fabric.Polygon( points: Array, options: Object ) Parameters

points − This parameter accepts an Array which denotes the array of points that make up the polygon object.

options (optional) − This parameter is an Object which provides additional customizations to our object. Using this parameter origin, stroke width and a lot of other properties can be changed related to the Polygon object.

Example 1: Default Appearance of Polygon Object

Let’s see a code example of how we can draw any general polygon object. We need to specify an array of points where each point is an object with x and y. Specifying the array of points is crucial without which our polygon object would not be rendered onto the canvas. We can also customize the polygon object by using various properties.

Here, we have customized our polygon object by assigning fill colour, stroke colour and setting the strokeWidth to 2.

var canvas = new fabric.Canvas(“canvas”); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(250);

var polygon = new fabric.Polygon( [ { x: 500, y: 20 }, { x: 550, y: 60 }, { x: 550, y: 200 }, { x: 350, y: 200 }, { x: 350, y: 60 }, { x: 500, y: 20 }, ], { fill: “black”, stroke: “blue”, strokeWidth: 2, } );

canvas.add(polygon);

Example 2: Drawing a Rectangle using Polygon

Let’s see a code example to see how we draw a rectangle using polygon. Since it is a rectangle, we need only four coordinates

var canvas = new fabric.Canvas(“canvas”); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(250);

var rectangle = new fabric.Polygon( [ { x: -240, y: 90 }, { x: 240, y: 90 }, { x: 240, y: -90 }, { x: -240, y: -90 }, ], { stroke: “red”, left: 140, top: 10, strokeWidth: 2, strokeLineJoin: “bevil”, } );

canvas.add(rectangle);

Conclusion

In this tutorial, we used two simple examples to demonstrate how you can draw a rectangle with Polygon using FabricJS.

How To Set Up A Vpn In Windows

Now that so many people are thrust into working from home due to the coronoavirus pandemic, we’ve confirmed that this procedure is up-to-date and working as described. You may want to check out our guide on working from home as well, with tech tips and general setup considerations from our extensive personal experience in home offices.

For the most part, VPN connections are handled by custom software such as the many consumer VPN services we’ve reviewed, or by third-party generic software such as the OpenVPN client or Cisco AnyConnect.

Another option that’s generally supported by most virtual private networks is to use Microsoft’s built-in VPN client. This is useful when some VPNs don’t provide their own client or if you want to use a VPN protocol not supported by your VPN’s client such as IKEv2. 

The downside to using the built-in client is that you have to select a specific server to use as opposed to jumping between different locations the way you can with a commercial VPN service. On the other hand, most employer-supplied VPNs will offer a limited number of servers you can connect to, which makes using this client ideal.

Step by step: How to set up a VPN in Windows 10

Windows 10’s built-in VPN client settings.

Windows 10’s built-in VPN client configuration window.

Step 5 Next fill out the “Connection name” and “Server name or address.” These vary based on your VPN provider—whether a third-party service or an employer. For this example, we’re using Acevpn, a clientless VPN service that supports various connection types such as IKEv2, L2TP, and PPTP.

The above process works for the easier VPN connection types such as PPTP and L2TP, but if you want to use IKEv2 that requires installing a root certificate from your VPN provider. Keep in mind that not every service supports IKEv2 so using this method depends greatly on your VPN service provider or employer.

Regardless, here’s how it works on Windows 10.

Windows 10’s Certificate Import Wizard.

Now that the certificate is installed we can set up the IKEv2 VPN using the same step-by-step instructions above. Just make sure that you select IKEv2 under “VPN type,” and then use the server name, address, and username and password provided by your service provider.

Once you’ve connected to the VPN, check to see that your VPN is working by visiting chúng tôi You should see an IP address, and DNS servers that are different from your non-VPN state. If you don’t, there are a number of potential causes that we can’t go into here. Your best bet is to check with your company’s IP department or the support service of your VPN.

Step-by-step: How to set up a VPN in Windows 7

Step 2 Enter the IP address or domain name of the server to which you want to connect. If you’re connecting to a work network, your IT administrator can provide the best address.

Step 7 If you can’t connect, the problem could be due to the server configuration. (There are different types of VPNs.) Check with your network administrator to see what kind is in use—such as PPTP—then, on the “Connect VPN Connection” screen, select Properties.

It takes a little work, but setting up a VPN using the Windows built-in client is relatively quick, and as a user it’s a helpful skill to have.

How To Set Margin For Individual Sides In Css?

Introduction to CSS Margin

Web development, programming languages, Software testing & others

Margin Properties

Other than setting precise margin values, CSS also allows us to set the following values as margin properties:

auto: With these options, we are letting the browser calculate the element’s margin

length: As mentioned before, we can specify a precise margin in px, pt, cm, etc.

%: We can specify margin value as a % of the width of the element containing it.

inherit: With this; we specify that the element’s margin value should be inherited from that of its parent element

Setting Margin for Individual Sides in CSS

CSS allows us to set margin values individually for each side of the elements with the following properties:

Margin-top: It sets the margin to the top of the element.

Margin-bottom: It sets the margin to the bottom of the element.

Margin-left: It sets a margin to the left of the element.

Margin-right: It sets the margin to the right of the element.

Or we can also use the shorthand margin property in CSS to set the margin on all sides of the element with a single definition, as shown below:

Example #1

Code:

.p1 { margin-top: 100px; } .p2 { margin-bottom: 100px; } .p3 { margin-right: 150px; } .p4 { margin-left: 80px; } Div { background-color: yellow; } The world’s most popular programming languages in today’s era are Java : Java has been holding position 1 or 2 for the world’s most popular languages since it’s inception.

The output of the above example in the browser window would be as follows:

Example #2

To set the margins of our choice in the above example, we had to define the margin values four times. Now let’s set the same margin values with margin shorthand property in the below example:

div { Margin : 100px 150px 100px 80px; } The world’s most popular programming languages in today’s era are Java : Java has been holding position 1 or 2 for the world’s most popular languages since it’s inception.

Output:

With the shorthand property, the output in the browser window would be as follows:

Conclusion

We can set the margin property of HTML elements either with individual properties like margin-left, margin-right, margin-top, and margin-bottom, or we can define all margin values with the help of margin shorthand value. Both will produce the same result. The only difference would be that the code with the shorthand property would be more efficient and easy to apply.

How To Set Up Wifi Hotspot In Windows 8

Last year, my roommate moved out of my apartment and ended up taking our wireless router. I didn’t want to wait for twenty-four hours for Amazon to send me my new router, so I decided to turn my PC into a wireless router (or hotspot). My PC, which was wired directly to my modem, turned out to be a great replacement for my router and allowed me to hook up to the internet via WiFi with my laptop and mobile devices.

There are two ways of turning your Windows 8 PC into a wireless router, and I will walk you through both.

1. Doing It from the Command Prompt

1. Press the “Windows + R” key combination to bring up a run box, type “ncpa.cpl” and hit enter.

5. The first thing we need to do is set up the wireless network; this is done using the “netsh” command.

netsh wlan

set

hostednetwork

mode

=allow

ssid

=

"How-To "

key

=

"Pa

$w0rd

"

Where “ssid” is the name of your network and “key” is the password you want users to connect with, it’s also worth mentioning that the access point is created with WPA2-PSK (AES) encryption.

6. Now we are ready to start broadcasting our network:

2. Virtual Router Plus

Fortunately, Virtual Router Plus, a free utility that adds WiFi hotspot capabilities to Windows 8, is a much easier alternative to setting up a hotspot through the command prompt.

First off, be really careful during setup. The software is not totally “free,” as the installer comes packed with adware. It’s easy enough to bypass if you pay attention, but potentially troublesome if you don’t.

After you install the program, it’ll pop open a help page in your browser, which you may need to verify whether you have the required device drivers. You can skip that for now; instead, try using the utility.

Conclusion

Now that you set up your PC to be able to emit wireless Internet, don’t throw out your router! A router is much faster than a PC hotspot. That being said, this is a cool alternative for times when you need wireless Internet in your house but don’t have access to a router.
