Is it usefull Adobe illustrator?

Adobe Illustrator is graphic-driven software used primarily for creating vector graphics. Developed alongside with Adobe Photoshop as a companion product, Adobe illustrator is used for creating logos, graphics, cartoons and fonts for the photo-realistic layouts of Adobe Photoshop


How Adobe Illustrator is Used ?

Adobe Illustrator is used to create a variety of digital and printed images, including cartoons, charts, diagrams, graphs, logos, and illustrations. #(social-stuf) Illustrator allows a user to import a photograph and use it as a guide to trace an object in the photograph. This can be used to re-color or create a sketch-like appearance of a photograph. Illustrator also makes it possible to manipulate text in many ways, making Illustrator a useful tool for creating postcards, posters, and other visual designs which use text and images together. Illustrator’s ability to place text around a curve is especially useful for artists creating logos. Illustrator is also used in designing mock-ups which show what the website will look like when it’s completed, and creating icons used within apps or websites.


Vector Graphics in Adobe Illustrator ?


One of Adobe Illustrator’s most important features is that the quality of artwork created using Illustrator is independent of the resolution at which it is displayed. This means that an image created in Illustrator can be enlarged or reduced without sacrificing image quality. This is an attribute of vector artwork, which uses mathematical relationships in describing lines, arcs, and other parts of an illustrator. By comparison, photographs edited using tools such as Adobe Photoshop are resolution-dependent, and image quality decreases when an image is enlarged. A vector graphic is a set of polygons that make up the image, which are in turn composed of vectors. Each vector passes through a location known as a node or control point, which has a defined location on the x and y axes on a plane. This node determines the vector’s path, which has various attributes such as color, curve, fill, shape and thickness. The position of vectors can be related to each other by mathematical formulas, which precisely recalculate their position when an image is resized.

File Formats Illustrator can Save
Illustrator’s ability to create and modify vector images means that must also save files in vector graphics formats. Some of these formats include Scalable Vector Graphics (SVG), Portable Document Format (PDF), Encapsulated PostScript (EPS), Windows Metafile (WMF) and Vector Markup Language (VML), which are detailed below:
  • PDF is a file format that Illustrator can export. It allows for images and text to display independently of hardware, software and OS. It encapsulates a complete description of flat documents with a fixed layout, including fonts, graphics and text. The PDF format includes a structured storage system that combines these elements and compresses them into a single file. It also includes a subset of PostScript to generate the graphics and a system for associating fonts with the documents.
  • EPS is a subset of the PostScript format with additional restrictions that allow it to store graphics files. These files are generally self-contained and may be placed within another PostScript file. An EPS file is essentially a PostScript program that contains a low-resolution preview of the image, which some applications are able to display. Earlier in its history, it was common to save Illustrator files into an EPS format for them to be shared with page layout applications.
  • WMF is a format that was originally used by Windows in the 1990s for which Illustrator could export. This format can store both vector graphics and bitmaps, allowing it to be used in a manner similar to the SVG format. WMF files contain a list of function calls that the Windows Graphics Device Interface (GDI) uses to display an image. A WMF can include executable code since some GDI functions perform error handling.
  • VML This was an XML-based format for two-dimensional vector graphics that was part of the Office Open XML standards. It’s no longer supported by Internet Explorer as of 2012, although it’s still included in Office Open XML for legacy purposes, and was originally supported by Illustrator.
  • SVG The SVG specification has been maintained by the World Wide Web Consortium (W3C) as an open standard since 1999. This format is based on Extended Markup Language (XML), which supports two-dimensional graphics for both animations and interactive images. SVG images are defined in XML files, allowing them to be compressed, indexed, scripted and searched. SVG files may be edited with any text editor and many other drawing applications. As a member of the W3C, Adobe supports this file format in Illustrator and other applications they produce.
