This tutorial will discuss how to write a swift program to find the perimeter of a Rectangle.A rectangle is a 2-dimensional closed shape with four sides in which opposite sides are parallel and equal to each other. It also has four angle with 90 degrees each.The perimeter of the rectangle is used to calculate the boundary of the rectangle. Or we can say that it is the total distance covered by the rectangle’s outer boundary as show in the above diagram. It is the one of the most important formula of the rectangle. Suppose we want to fence our rectangular ... Read More
This tutorial will discuss how to write a swift program to calculate the simple interest and compound interest. Compound Interest The interest applied on the principal and interest together over a certain period of time is known as the compound interest. Or in other words compound interest is known as the interest on interest. It is calculated after calculating amount. Formula Following is the formula of compound interest − Amount(A) = Principal(P)(1 + Rate/100)Time(t)C.I = Amount(A) - Principal(P) Where Principal(P) − Principal amount represents the amount which is initially invested. Rate(R) − Rate represents the interest rate which applied ... Read More
In this tutorial, we are going to learn how to set the width of a Textbox using FabricJS. We can customize, stretch or move around the text written in a textbox. In order to create a textbox, we will have to create an instance of fabric.Textbox class and add it to the canvas. However, one of the fundamental properties of textbox is width which specifies the horizontal width of the textbox. Syntax new fabric.Textbox(text: String, { width: Number }: Object) Parameters text − This parameter accepts a String which is the text string that we want to display ... Read More
In this tutorial, we are going to learn how to set the vertical scale factor of a Textbox using FabricJS. We can customize, stretch or move around the text written in a textbox. In order to create a textbox, we will have to create an instance of fabric.Textbox class and add it to the canvas. Just as we can specify the position, colour, opacity and dimension of a textbox object in the canvas, we can also set the vertical scale factor of a textbox object. This can be done by using the scaleY property. Syntax new fabric.Textbox(text: String, { scaleY ... Read More
In this tutorial, we are going to learn how to set the style of controlling corners of Textbox using FabricJS. We can customize, stretch or move around the text written in a textbox. In order to create a textbox, we will have to create an instance of fabric.Textbox class and add it to the canvas. The controlling corners of an object allow us to scale, stretch or change its position. We can customize our controlling corners in many ways such as adding a specific colour to it, changing its size, etc. We can change the style by using the cornerStyle ... Read More
In this tutorial, we are going to learn how to set the size of the controlling corners of a Textbox using FabricJS. The controlling corners of an object allow us to scale, stretch or change its position. We can customize our controlling corners in many ways such as adding a specific colour to it, changing its size etc. We can change the size by using the cornerSize property. Syntax new fabric.Textbox(text: String, { cornerSize: Number }: Object) Parameters text − This parameter accepts a String which is the text string that we want to display inside our textbox. ...

In this tutorial, we are going to set the position of Textbox from top using FabricJS. The top property allows us to manipulate the position of the object. We can customize, stretch or move around the text written in a textbox. In order to create a textbox, we will have to create an instance of fabric.Textbox class and add it to the canvas. By default, the top position is relative to the canvas’s top edge. Syntax new fabric.Textbox(text: String, { top: Number }: Object) Parameters text − This parameter accepts a String which is the text string that ... Read More
In this tutorial, we are going to learn how to set the position of a Textbox from the left using FabricJS. We can customize, stretch or move around the text written in a textbox. In order to create a textbox, we will have to create an instance of fabric.Textbox class and add it to the canvas. The position from left can be changed by using the left property. Syntax new fabric.Textbox(text: String, { left: Number }: Object) Parameters text − This parameter accepts a String which is the text string that we want to display inside our textbox. ... Read More
