The process involves partitioning a comp in either a single layer [image file format] or the multi-layer native file format of the graphic art software used for partitioning. Once partitioned, one would save them as separate image files, typically in GIF, JPEG or PNG format in either a batch process or one at a time. Multi-layered image files may include multiple versions or states of the same image, often used for animations or widgets.
Practical usage
Slicing is used in many cases where a graphic design layout must be implemented as interactive media content. Therefore, this is a very important skill set typically possessed by "front end" developers; that is interactive media developers who specialize in user interface development.
Slices may be produced and used in several different ways. Before tableless web design, sliced images were held together precisely with html tables. Modern interactive page layout includes extensive use of Cascading Style Sheets (CSS) and semantic markup. Tables may be used for compatibility with rarer older web browsers that are incapable of processing modern tableless coding accurately.
Slicing reduces work loads and computer data storage space requirements to needing only the part of a dynamic image that changes instead of the whole image. If the slice is on a transparent multi-layered image, it can be reused in multiple parts of an image without changing the background.
On the web, slicing breaks up one large image into many smaller ones, which reduces "page weight" or load time considerably[citation needed]. Advanced methods of slicing can be used to further compress the amount of data needed to download to the user's computer in order for the web page to display correctly. Techniques such as repeating background images mean that one small image can be downloaded from the web server only once and then be instructed (via a CSS) to repeat by the markup language, shifting the work load from the web server onto the client's computer. Certain performance issues can be raised, however they are typically negligible compared with today's technology and trends of web design shifting towards rich media websites that typically require high bandwidth connectivity and recent computing hardware.
In offline electronic media, individually sliced sections of a 2D image can be used to decrease the local computer processing requirements to change a section of that image.
Tools
Quite a few industry standard programs offer the abilities to automatically slice a layout directly into tables using built in functions. These are outlined below:
Recent versions of these programs have improved ability to convert artwork directly into CSS, albeit an unorthodox method since the algorithms rely heavily on absolute positioning (for example), which can render (display) inconsistently across modern web browsers.
Alternatives
Slicing is mainly used for 2D computer graphics with single-layered interfaces. Multi-layered interfaces may use slices, but may also use vector graphics (including 3D models) with the drawback of added (most often unnoticeable) rendering time and with the advantage of more options and flexibility in altering the appearance of the individual image. These alternate individual images are commonly referred to as sprites.
Adobe Photoshop is a raster graphics editor developed and published by Adobe for Windows and macOS. It was originally created in 1987 by Thomas and John Knoll. Since then, the software has become the most used tool for professional digital art, especially in raster graphics editing. Owing to its fame, the program's name has become genericised as a verb although Adobe disapproves of such use.
Web design encompasses many different skills and disciplines in the production and maintenance of websites. The different areas of web design include web graphic design; user interface design ; authoring, including standardised code and proprietary software; user experience design ; and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. The term "web design" is normally used to describe the design process relating to the front-end design of a website including writing markup. Web design partially overlaps web engineering in the broader scope of web development. Web designers are expected to have an awareness of usability and be up to date with web accessibility guidelines.
Desktop publishing (DTP) is the creation of documents using dedicated software on a personal ("desktop") computer. It was first used almost exclusively for print publications, but now it also assists in the creation of various forms of online content. Desktop publishing software can generate page layouts and produce text and image content comparable to the simpler forms of traditional typography and printing. This technology allows individuals, businesses, and other organizations to self-publish a wide variety of content, from menus to magazines to books, without the expense of commercial printing.
Adobe Illustrator is a vector graphics editor and design software developed and marketed by Adobe. Originally designed for the Apple Macintosh, development of Adobe Illustrator began in 1985. Along with Creative Cloud, Illustrator CC was released. The latest version, Illustrator 2024, was released on October 10, 2023, and is the 28th generation in the product line. Adobe Illustrator was reviewed as the best vector graphics editing program in 2021 by hpMagazine.
Adobe Fireworks was a bitmap and vector graphics editor, which Adobe acquired in 2005. Fireworks was made for web designers for rapidly creating website prototypes and application interfaces. Its features included slices, which are segments of an image that are converted to HTML elements, and the ability to add hotspots, which are segments of an image that are converted to hyperlinks. It was designed to integrate with other Adobe products such as Adobe Dreamweaver and Adobe Flash. It was available as either a standalone product or bundled with Adobe Creative Suite. Older versions were bundled with Macromedia Studio. Adobe discontinued Fireworks in 2013, citing the increasing overlap in functionality with its other products such as Adobe Photoshop, Adobe Illustrator, and Adobe Edge.
A user interface markup language is a markup language that renders and describes graphical user interfaces and controls. Many of these markup languages are dialects of XML and are dependent upon a pre-existing scripting language engine, usually a JavaScript engine, for rendering of controls and extra scriptability.
A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program. Some programs are more suitable for artistic work while others are better for technical drawings. Another important factor is the application's support of various vector and bitmap image formats for import and export.
In graphic design, page layout is the arrangement of visual elements on a page. It generally involves organizational principles of composition to achieve specific communication objectives.
An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy compression or lossless compression. For graphic design applications, vector formats are often used. Some image file formats support transparency.
Tableless web design is a web design method that avoids the use of HTML tables for page layout control purposes. Instead of HTML tables, style sheet languages such as Cascading Style Sheets (CSS) are used to arrange elements and text on a web page.
Graphic art software is a subclass of application software used for graphic design, multimedia development, stylized image development, technical illustration, general image editing, or simply to access graphic files. Art software uses either raster or vector graphic reading and editing methods to create, edit, and view art.
Digital scrapbooking is the term for the creation of a new 2D artwork by re-combining various graphic elements. It is a form of scrapbooking that is done using a personal computer, digital or scanned photos and computer graphics software. It is a relatively new form of the traditional print scrapbooking.
The Yahoo! User Interface Library (YUI) is a discontinued open-source JavaScript library for building richly interactive web applications using techniques such as Ajax, DHTML, and DOM scripting. YUI includes several cores CSS resources. It is available under a BSD License. Development on YUI began in 2005 and Yahoo! properties such as My Yahoo! and the Yahoo! front page began using YUI in the summer of that year. YUI was released for public use in February 2006. It was actively developed by a core team of Yahoo! engineers.
Preview is a computing function to display a document, page, or film before it is produced in its final form. In the case of printed material this is known as "print preview".
