Question: When there is JPEG, why
do we still use GIF files for graphics in WWW page?
Well, the only two standard graphics files for WWW pages
are JPEG and GIF. JPEG gives excellent compression, especially
for photographs. It also gives 16.7 million colors, and has
been designed to compress objects which have a good deal of
change within the graphic. GIF files are limited in that they
can only display 256 colors at a time (from a range of 16.7
colors). But GIF is very good a compressing graphics which
do not have a great amount of change, especially small graphics,
such as little images. The other great advantage is that GIF
files support transparency, where parts of the images can
be made transparent, so that the background color will be
show wherever there is transparency.

WWW pages of the past
(Aug 2000)
|
| August
2000.
This is my latest WWW page, and I think it is starting
to look a little cluttered, as my original design isn't
really coping with my new pages. Thus I'll be working
on a new WWW design, which is relatively simple, and usable
(not an easy thing). The design is based on a table (although
it simulates frames, as all the sub-pages are built with
the same table format. Most of the sub-pages have the
same menu options on the left hand side column. As these
are repeated graphics the sub-page does not have to resend
these graphics images, thus, once the page has loaded,
it should not take too long to load all the resultant
pages.
I've tried to minimize the usage of Flash on the
main page (just in case that the Flash Player is not installed,
but I've included a little graphic on the top right-hand
side which displays the word Home, which gently appears,
one letter at a time. |
