When it comes to picking an image type there are tonss to take from, these image types can be broken down into classs, from raster artworks, vector artworks and stereo artworks. In each class there are a scope of formats, raster artworks has the most formats followed by vector.

Raster Artworks are normally referred to as electronic image, ground for this harmonizing to ( Gumster 2010 ) “ Each pel in the image has its ain coloring material and that coloring material is mapped to a grid that forms the full size of the image. ” Raster artworks are best used for extremely elaborate images, like images of people or landscapes when you need the image to look realistic, there is a cost for good quality images as you increase the pels you have in a electronic image are stored as one or more spots in your computing machine ‘s memory. So if


your image has tonss of colorss and pels it will take up much more memory than an image that low in colors and pels.

The most popular and common raster file formats used are labeled image file formats ( TIFF ) , Joint Photographic Experts Group ( JPEG ) , Graphics Interchange Format ( GIF ) and Bitmap Image File ( BMP ) . Below are elaborate descriptions of the popular formats and brief descriptions of the less popular formats:

TIFF – The ground for this format being popular is due to it being the most widely supported format on all operating systems. Tiff is good for exposing coloring material, grayscale and black and white images.TIFF was release in 1986 and is held by Adobe and prior to that was Aldus Corporation, harmonizing to ( Savage 2008 ) “ TIFF was originally designed for usage with scanners. It is the format multimedia developers normally use both for scanned images and for files to be used in authoring applications ” .

JPEG – Is one of the chief image formats that is support on the universe broad web. JPEG is normally used for compacting informations by acquiring rid of some informations from the image ; it is difficult to detect the alteration in image quality if the compaction is little as 15 % but if you were to compact the image to state 85 % there would be noticeable degrading of the image, 60 % compaction is good for acquiring an optimal balance between quality and size. Below is an illustration of image compaction for 15 % and 85 %

JPEG 2000 – This format was created to replace the old format of JPEG with the newer version JPEG 2000, this newer version was created in 2000 and that ‘s how it got its name. Like JPEG it was created by the Joint Photographic Experts Group. The file extensions used for JPEG

2000 are.jp2 and.j2k.

BMP – Bitmap Image File is used for windows runing systems as it was created by Microsoft. BMP files are frequently really big compered to JPEG ‘s, this is down to them non utilizing lossy compaction. A “ electronic image file is a raster- ( or pixel- ) based format that merely supports the RGB coloring material infinite and spot deepnesss of 1, 4, 8, or 24 spots per channel ” ( from an article by The Sheridan Group, 2001 )

GIF – Graphics Interchange Format was developed by CompuServe in 1987 and is the most popular file format on the cyberspace and this is due to its little size, as its lone 8- spot and is used for icons. GIF files can utilize lifes like streamers or short amusing cartridge holders. GIF uses loss-less, so it can cut down the file size without impacting the quality of the file.

Exif – Exchangeable Image File that is used by digital cameras, scanners and smart phones like the humanoid.

RAW – Natural image file is a file that is non to the full processed and that ‘s how it got its name. It is similar to a negative in picture taking, as it ‘s an image that is non to the full processed.

PNG – Portable Network Graphics file format was created as there were a few large restrictions with another format that was the GIF format, so it was created to seek and better upon GIF and to supply a format without the demand for a patent licence, and intern replace the GIF format.

WEBP – This is a new image format that was created by Google to seek and cut down the burden clip on web pages by holding a file format that was little in size ; this would let the web pages to open quicker. So WEBP is smaller images that look good and better your web surfboarding.

Vector Artworks

Vector artworks are different to raster artworks, as vector artworks use instructions to re-create an image, non like raster artworks that are created by spliting the image into a grid of pels. Storage advantages for vector artworks harmonizing to ( June Parsons 2008 ) ” Each direction requires storage infinite, so the more lines, forms and fill forms in the graphic, the more storage infinite it requires. Even so, vector artworks normally require less storage infinite so a electronic image artworks and resize better than a electronic image artwork ” .

The most popular vector file formats used are Computer Graphics Metafile ( CGM ) , Portable Document Format ( PDF ) and Scalable Vector Graphics ( SVG ) Below are elaborate descriptions of the popular formats and brief descriptions of some of the less popular formats:

CGM – Computer Graphics Metafile is a really of import as it was designed to back up artworks applications and is used alto in computing machine aided design ( CAD ) . CGM is one of a little smattering of in writing formats that is an International Standard ( ISO ) and is non a de facto criterion.

SVG – Scalable Vector Graphics was and is still
