Adobe Illustrator is used to create a variety of digital and printed images, including cartoons, charts, diagrams, graphs, logos, and illustrations. Illustrator allows a user to import a photograph and use it as a guide to trace an object in the photograph.
Adobe Illustrator is a software application for creating drawings, illustrations, and artwork using a Windows or MacOS computer. Illustrator was initially released in 1987 and it continues to be updated at regular intervals, and is now included as part of the Adobe Creative Cloud. Illustrator is widely used by graphic designers, web designers, visual artists, and professional illustrators throughout the world to create high quality artwork. Illustrator includes many sophisticated drawing tools that can reduce the time need to create illustrations.
Adobe Illustrator is used to create a variety of digital and printed images, including cartoons, charts, diagrams, graphs, logos, and illustrations. 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.
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. The position of vectors can be related to each other by mathematical formulas, which precisely recalculate their position when an image is resized.
This property of vector graphics is different when compared to imaging software such as Photoshop, which uses pixel grids to render images. When this type of image is scaled up sufficiently, the individual pixels comprising a bit map become visible. This phenomenon results in a loss of image quality known as pixilation, which makes Illustrator especially advantageous for creating large images such as a billboard sign.
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. 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.
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.
