Clip art, in the graphic arts, refers to pre-made images used to illustrate any medium. Today, clip art is used extensively in both personal and commercial projects, ranging from home-printed greeting cards to commercial candles^{[citation needed]}. Clip art comes in many forms, both electronic and printed. However, most clip art today is created, distributed, and used in an electronic form. Since its inception, clip art has evolved to include a wide variety of content, file formats, illustration styles, and licensing restrictions. Clip art is generally composed exclusively of illustrations (created by hand or by computer software), and does not include stock photography.

History

The term "clip art" originated through the practice of physically cutting images from pre-existing printed works for use in other publishing projects. Before the advent of computers in publishing, clip art was used through a process called paste up. Many clip art images in this era qualified as line art. In this process, the clip art images are cut out by hand, then attached via adhesives to a board representing a scale size of the finished, printed work. After the addition of text and art created through phototypesetting, the finished, camera-ready pages are called mechanicals. Since the 1990s, nearly all publishers have replaced the paste up process with desktop publishing.

After the introduction of mass-produced personal computers such as the IBM PC in 1981 and the Apple Macintosh in 1984, the widespread use of clip art by consumers became possible through the invention of desktop publishing. For the IBM PC, the first library of professionally drawn clip art was provided with VCN ExecuVision, introduced in 1983. These images were used in business presentations, as well as for other types of presentations. Many people credit Apple Computer with providing desktop publishing with the tools required to make it a reality for consumers, with the introduction of the Macintosh's graphical user interface (GUI) in 1984 and the LaserWriter laser printer in late 1985. After software maker Aldus introduced PageMaker in 1985, professional quality desktop publishing became possible with consumer desktop computers.

After 1986, desktop publishing generated a widespread need for pre-made, electronic images as consumers began to produce newsletters and brochures using their own computers. Electronic clip art emerged to fill the need. Early electronic clip art was simple line art or bitmap images due to the lack of sophisticated electronic illustration tools. With the introduction of the Apple Macintosh program MacPaint, consumers were provided the ability to edit and use bitmapped clip art for the first time.

One of the first successful electronic clip art pioneers was T/Maker Company, a Mountain View, California company which had its early roots with an alternative word processor, WriteNow, commissioned for the Macintosh by Steve Jobs. Beginning in 1984, T/Maker took advantage of the capability of the Macintosh to provide bitmapped graphics in black and white; by publishing small, retail collections of these images under the brand name "ClickArt." The first version of "ClickArt" was a mixed collection of images designed for personal use. The illustrators who created the first "serious" clip art for business/organizational (professional) use were Mike Mathis, Joan Shogren, and Dennis Fregger; published by T/Maker in 1984 as "ClickArt Publications."

In 1986, Adobe Systems introduced Adobe Illustrator for the Macintosh, allowing home computer users the first opportunity to manipulate vector art in a GUI. This made the higher-resolution vector art possible and in 1987 T/Maker published the first vector-based clip art images, despite widespread unfamiliarity with the bezier curves required to edit vector art. However, graphic designers and many consumers quickly realized the enormous advantages of vector art, and T/Maker's clip art became the gold standard of the industry in the late 1980s and early 1990s. In 1994, T/Maker was sold to Deluxe Corp and then two years later to its main rival, Broderbund.

With widespread adoption of the CD-ROM in the early 1990s, several pre-computer clip art companies such as Dover Publications also began offering electronic clip art.

The mid-1990s ushered in more innovation in the clip art industry, as well as a marketing focus on quantity over quality. Even T/Maker, whose success was built upon selling small, high quality clip art packages of approximately 200 images, began to get interested in the volume clip art market. In March, 1995, T/Maker became the exclusive publisher of over 500,000 copyright-free images which was, at the time, one of the world's largest clip art libraries. This licensing agreement was subsequently transferred to Broderbund.

Also during this period, word processing companies, including Microsoft, began offering clip art as a built-in feature of their products. In 1996, Microsoft Word 6.0 included only 82 WMF clip art files as part of its default installation. Today, Microsoft offers clip art as part of over 140,000 media elements in the Microsoft Office product suite.

Other companies such as Nova Development and Clip Art Incorporated also pioneered the marketing of large clip art collections in the late 1990s, including Nova's "Art Explosion" series, which sold clip art in increasingly large libraries up to a million images.

Between 1998 and 2001, T/Maker's clip art assets were sold each year as a result of some of the largest mergers and acquisitions in the computer software industry, including those of The Learning Company (in 1998) and Mattel (in 1999). All of T/Maker's clip art is currently marketed through the Broderbund division of the Irish company Riverdeep.

In the early 2000s, the World Wide Web continued to gain popularity as a retail software distribution channel, and several companies pioneered the sale of clip art through online, searchable libraries, including Clipart.com (part of Jupiter Media), WeddingClipart.com (part of Letters and Arts Incorporated), and GraphicsFactory.com (part of Clip Art Incorporated). Because of the Web, clip art is now not only sold through retail channels as packaged bundles of images, but also as individual images and subscriptions to entire libraries (which allow you to download an unlimited number of images for the duration of the subscription).

In the mid-2000s, the clip art market is segmented in several different ways, including the data type, the art style, the delivery medium, and the marketing method.

Clip art is divided into two different data types represented by many different file formats: bitmap and vector art. Clip art vendors may provide images of just one type or both. The delivery medium of a clip art product varies from different types of traditionally boxed retail packages to online download sites. Clip art is sold via both traditional and web-based retail channels (as with Nova Development products), as well as via online, searchable libraries (as with Clipart.com). Clip art vendors typically market clip art by focusing either on quantity or vertical market specialty. The marketing method often goes hand in hand with the art style of the clip art sold.

To compete largely on quantity, some clip art vendors must produce or license new and old clip art collections in volume. Clip art marketed in this way is often less expensive but simpler in structure and detail, as is typified by cartoons, line art, and symbols (e.g. Nova Development, http://www.iClipart.com and http://www.GraphicsFactory.com). Clip art which is sold according to smaller, specialized subject genres tends to be more complex, modern, detailed, and expensive (e.g. WeddingClipart.com, GoodSalt.com).

File Formats

Electronic clip art is available in several different file formats. It is important for clip art users to understand the differences between file formats so that they can use an appropriate image file and get the resolution and detail results they need.

Clip art file formats are divided into 2 different types: bitmap or vector graphics.

Bitmap (or "rasterized") file formats are used to describe rectangular images made up of a grid of multicolored or black and white pixels. Scanned photos, for example, make use of a bitmap file format. Bitmap images are always limited in quality by their resolution, which must be fixed at the time the file is created. If the image is not rectangular, then it is saved on a default background color (usually white) defined by the smallest bounding rectangle in which the image fits.

Because of their fixed resolution, printing bitmap images can easily produce grainy, jaggy, or blurry results if the resolution is not ideally suited to the printer resolution. In addition, bitmap images become grainy when they are scaled larger than their intended resolution. A few bitmap file formats (such as Apple's PICT format) support alpha channels, which allow bitmap images to have transparent backgrounds or an image selection which uses antialiasing. Most common web-based file formats such as GIF, JPEG, and PNG are bitmap file formats. The GIF file format is one of the simplest, low-resolution bitmap file formats, only supporting 256 colors per image. As a result, however, GIF files can be extremely small in file size. Other common bitmap file formats are BMP (Windows bitmap), TGA, and TIFF. Most clip art is provided in a low resolution, bitmap file format which is unsuitable for scaling, transparent backgrounds, or good-quality printed materials. However, bitmap file formats are ideal for photos, especially when combined with lossy data compression algorithms such as those available for JPEG files.

In contrast to the grid format of bitmap images, Vector graphics file formats use geometric modeling to describe an image as a series of points, lines, curves, and polygons. Because the image is described using geometric data instead of fixed pixels, the image can be scaled to any size while retaining "resolution independence", meaning that the image can be printed at the highest resolution a printer supports, resulting in a clear, crisp image. Vector file formats are usually superior in resolution and ease of editing as compared to bitmap file formats, but are not as widely supported by software and are not well-suited for storing pixel-specific data such as scanned photographs. In the early years of electronic clip art, vector illustrations were limited to simple line art representations. However, by the early 2000s, vector illustration tools could produce virtually the same illustrations as bitmap illustration tools, while still providing all of the advantages of vector file formats. The most common vector file format is Adobe's EPS (Encapsulated PostScript) file format. Microsoft has a much simpler, less sophisticated vector file format called WMF (Windows Metafile). The World Wide Web Consortium has developed a new, XML-based vector file format called SVG (Scalable Vector Graphics) which may be supported by all web browsers in the future (Firefox and Opera currently support the format). For those with image-editing experience or interest to work with vector file formats, vector clip art provides the most flexible, highest quality images.

Image Rights

All clip art usage is governed by the terms of individual copyrights and usage rights. The copyright and usage rights of a clip art image are important to understand so that the image is used in a legal, permitted way. The three most common categories of image rights are royalty free, rights managed, and public domain.

Most commercial clip art is sold with a limited royalty free license which allows customers to use the image for most personal, educational and non-profit applications. Some royalty free clip art also includes limited commercial rights (the right to use images in for-profit products). However, royalty free image rights often vary from vendor to vendor.

Some fine art clip art is still sold on a rights managed basis. However this type of image rights have seen a steep decline in the past 20 years as royalty free licenses have become the preferred model for clip art.

Public domain images continue to be one of the most popular types of clip art because the image rights are free. However, many images are erroneously described as part of the public domain are actually copyrighted, and thus illegal to use without proper permissions. The main cause for this confusion is because once a public domain image is redrawn or edited in any way, it becomes a brand new image which is copyrightable by the editor.

The United States District Court ruled in 1999 as part of Bridgeman Art Library v. Corel Corp that exact copies of public domain images were not protected by US copyright law, however the scope of this ruling only applies to photographs currently. It is originality, not skill, experience or effort, which affects copyrightability of derivative images. In fact, the US Supreme Court in Feist v. Rural ruled that the difficulty of labor and expenses must be rejected as considerations in copyrightability.

Copyright on other clipart stands in contrast to exact replica photographs of paintings. The large clip art libraries produced by Dover Publications or the University of South Florida's Clipart ETC project are based on public domain images, but because they have been scanned and edited by hand, they are now derivative works and copyrighted, subject to very specific usage policies. In order for a clip art image based on a public domain source to be truly in the public domain, the proper rights must be granted by the individual or organization which digitized and edited the original source of the image.

The popularity of the Web has facilitated widespread copying of pirated clip art which is then sold or given away as "free clip art". The reality is that most clip art touted as "free" is actually illegally distributed.^{[citation needed]} Virtually all images published after January 1, 1923 still have copyright protection under the federal laws of most countries. Images published prior to 1923 need to be carefully researched to make sure they are in the public domain.^{[citation needed]} Creative Commons licenses is the forefront of the copyleft movement or a new form of free digital clipart and photo image distribution. Many website such as Flickr and Interartcenter use Creative Commons as an alternative to the full attribution copyrights.

The exception for clip art illustrations created after 1923 are those which are specifically donated to the public domain by the artist or publisher. For vector art, the open source community established the Open Clip Art Library in 2004 as a clearinghouse for images which are legitimately donated to the public domain by their copyright owners. By 2010, the library contained near 40,000 vector images.
