• A local band would like a logo designed for their website this needs to be combined with their band photo.

For this customer I need type of graphic GIF( Indexed colour file, for raster (pixmap) data only. Primarily for synthetic, somewhat flat images such as logos, diagrams, navigation ).Uses a CLUT (colour lookup table) to define the colours as though they were individual colour chips, and only supports up to 256 colours per image. Although it can simulate continuous-tone colours by dithering, that’s generally best left to the JPEG or PNG formats. GIF87 was the original Web graphic file format, way back in 1993. The current version, GIF89a, supports 1-bit (jagged-edge) transparency, comments, and simple animation.GIF is your best Web option for images with flat, solid colours — the sort of images you normally create in vector drawing programs such as Illustrator. Of course we’d love to put our Illustrator images on the Web in their original vector form, but for the most part that’s not possible (but sees SVG lower down in this table). So we export our vectors to raster formats like GIF or PNG for the Web.GIF is rarely a good choice for non-Web use.

• A builder wants some eye catching text for the side of his van to improve business opportunities.

For this customer I need type of graphic GIF or JPEG (Ccompressed, lossy file format, for raster pixmap data only. Mostly for photo-type images on the Web. Can hold RGB data; many compression levels and other options available).For Web, digital camera storage, and stock photo dissemination. (By the way, this latter use is counter-intuitive, since it’s a loss format and stock photos are often intended for high-end prepress work; but in this kind of use the files are so huge, and the compression applied so minimal, that there’s no significant data loss.) But for everyday use — which generally means in Web development — the looseness is a major issue. The trade-off is between file size and quantization artefacts. There are many variants and choices to be made in exporting JPEGs. Many people save JPEGs from Photoshop’s built-in “Save for Web” dialog, but there are lots of other programs — including Web-specific graphics applications like Fireworks — that can save JPEGs. Each has its own vagaries. Be aware that the JPEG “quality” in these programs have no universal meaning and are not standard across programs; they’re only meaningful for comparisons within the same program.

• The nursery on your estate would like a flyer designed to promote the facility.

For this customer I need type of graphic GIF or SVG (Attempt to introduce a standard vector format for the Web).This is a text-based graphics language that describes images with vector shapes, text, and embedded raster graphics. SVG files provide resolution independent, high resolution dots per inch (HiDPI) graphics on the web, in print, and on mobile devices in a compact format. The ability to style SVG with CSS and the support of scripting and animation makes SVG an integral part of the web platform. SVG is used in many business areas including Web graphics, animation, user interfaces, graphics interchange, print and hardcopy output, mobile applications and high-quality design.SVG is a royalty-free vendor-neutral open standard developed under the W3C Process. It has strong industry support; Authors of the SVG specification include Adobe, Agfa, Apple, Canon, Corel, Ericsson, HP, IBM, Kodak, Macromedia, Microsoft, Nokia, Sharp and Sun Microsystems. SVG viewers are deployed to over 100 million desktops, and there is a broad range of support in many authoring tools.
