- 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.
