Adobe Illustrator is a software application that creates drawings, illustrations, and artwork using a Windows or MacOS computer. Illustrator was originally released in 1987 and has been updated regularly and is now included as part of Adobe Creative Cloud.
It is widely used by web designers, professional illustrators, graphic designers, and visual artists all around the world to make high quality works of art. Illustrator has many advanced drawing tools that can reduce the time it takes to create illustrations.
How Adobe Illustrator is Used
Adobe Illustrator is used to create a variety of digital and printed images, including cartoons, charts, drawings, graphs, logo, and images. Illustrator allows the user to import an image and use it as a follow-up object to an image.
This can be used to re-color or create an image that looks like a skirt. Illustrator also enables us to use text in many ways, making Illustrator a useful tool for creating postcards, posters, and other graphic designs that use text and images together.
The ability of Illustrator to put text around a curve is of great importance to the artists who create the logo. Illustrator is also used to create mock-ups that show what a website will look like when finished, and to create icons for use within apps or websites.
Vector Graphics in Adobe Illustrator
One of the most important features of Adobe Illustrator is that the quality of the artwork created using Illustrator is independent of the resolution it displays. An image created in Illustrator can be expanded or reduced without sacrificing image quality.
This is a characteristic of vector artwork, which uses mathematical relationships to illustrate lines, arcs and other parts of the illustrator.
In comparison, edited photographs using tools such as Adobe Photoshop are based on resolution and the image quality decreases as the image expands. A vector graphic is a set of polygons that make up an image, composed of vectors.
Each vector passes through a region called a node or control point, which has a defined position on the x and y axes of the plane. This node determines the path of the vector, which has different properties such as color, curvature, fill, shape and thickness.
The position of the vectors is related to each other by mathematical formulas that accurately calculate their position when an image is resized.
This property of vector graphics is different as compared to imaging software such as adobe Photoshop. When this type of image is scaled enough, individual pixels with a bitmap appear.
This phenomenon results in the loss of image quality known as pixelation, which makes the illustrator particularly advantageous for making large images, such as the billboard mark.
File Formats Illustrator can Save
Illustrator’s ability to create and edit vector images also means that files must be saved in vector graphics formats. Some of these formats include SVG, PDF, EPS, WMF and VML, described below:
Pdf Illustrator Exportable File Format: It allows images and text to be displayed independently of hardware, software and the OS. It combines a full description of flat documents with a fixed layout including fonts, graphics and text. The pdf format contains a structured storage system that combines these elements and compresses them into a single file. It also includes a subset of Postscript to create graphs and a system that associates fonts with documents.
EPS: it is a subset of PostScript format that allows you to store graphics files with additional limitations. These files are usually self-contained and can be placed in another PostScript file. The EPS file is essentially a PostScript program that contains a low-resolution preview of the image, which some applications can display. Earlier in its history, it was common to store illustrator files in EPS format for sharing with page layout applications.
WMF: it is a format used by Windows in the 1990s for which Illustrator can be exported. This format can store vector graphics and bitmaps, allowing it to be used in a manner similar to the SVG architecture. WMF files contain a list of function calls used to display the Windows Graphics Device Interface (GDI) image. WMF contains executable code because some GDI functions perform error handling.
VML: It is an XML-based format for 2-dimensional vector graphics that is the part of Office Open XML. Although it is still included in Office Open XML for legacy purposes, Internet Explorer does not support it as of 2012 and is actually supported by Illustrator.
SVG: The SVG specification has been maintained by the World Wide Web Consortium (W3C) since 1999 as an open standard. This format is based on XML, which supports 2 dimensional graphics for interactive images and animations. SVG images are defined in XML files, allowing them to compress, index, script and search. SVG files can be edited with any text editor and many other drawing applications. As a W3C member, this file format is supported in Adobe Illustrator and other applications they produce.
