Technical Glossary

Pixel and resolution: The term "pixel" is actually short for "Picture Element." These small little dots are what make up the images on computer displays, whether they are flat-screen (LCD) or tube (CRT) monitors. The display resolution of a digital television, computer monitors or display device is the number of distinct pixels in each dimension that can be displayed.

File formats and uses: Bmp: Bmp is simply a bitmap. It is a raster graphics image file format used to store bitmap digital images, independently of the display device.Png: Png stands for portable network graphics. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the World Wide Web.Gif: Gif stands for Graphics interchange format. The format supports up to 8 bits per pixel thus allowing a single image to reference a palette of up to 256 distinct colors. The colors are chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of 256 colors for each frame. The color limitation makes the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for simpler images such as graphics or logos with solid areas of color.Tiff: This stands for tagged image file format. It is a file format for storing images, popular among graphic artists, the publishing industry, and both amateur and professional photographers in general.Jpg: JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.Psd: It stands for Photoshop document, the default file extension of the proprietary file format of Adobe System's Photoshop program.Pdf: This stands for portable document format. It is a file format used to represent documents in a manner independent of application software, hardware, and operating systems. Eps: This means encapsulated postscript. It is a DSC-conforming PostScript document with additional restrictions which is intended to be usable as a graphics file format.Ai: This stands for Adobe illustrator artwork. It is a proprietary file format developed by Adobe Systems for representing single-page vector-based drawings in either the EPS or PDF formats.

Compression: File compression is used to reduce the file size of one or more files. When a file or a group of files is compressed, the resulting "archive" often takes up 50% to 90% less disk space than the original file(s). Common types of file compression include Zip, Gzip, RAR, StuffIt, and 7z compression. Each one of these compression methods uses a unique algorithm to compress the data.

Image captures devices: The use of a device, such as a scanner or digital camera, to create a digital representation of an image. This digital representation can then be stored and manipulated on a computer.

Optimising: Optimise means modify to achieve maximum efficiency in storage capacity or time or cost; "optimize a computer program”.Storage and asset management: Digital asset management (DAM) consists of management tasks and decisions surrounding the ingestion, annotation, cataloguing, storage, retrieval and distribution of digital assets. Digital photographs, animations, videos and music exemplify the target areas of media asset management (a sub-category of DAM).
