9. Lets take a focus on
images.

10. An image
can also be
described in
terms
ofvector
graphicsor
raster
graphics.

is a “lossy” format meaning
that the image is compressed
to make a smaller file. The
compression does create a
loss in quality but this loss is
generally not noticeable.
JPEG files are very common
on the Internet and JPEG is a
popular format for digital
cameras -making it ideal for
web use and non-
professional prints.
Scalable
Vector

.svg
Vector image format; ideal
for user interface elements,
icons, diagrams, etc., that
must be drawn accurately at
different sizes.

22. WMF

.png
area lossless image format
originally designed to
improve upon and replace
the gif format. PNG files are
able to handle up to 16
million colors, unlike the 256
colors supported by GIF.

.wmf
WMF files are structured by a
series of records, starting
with a number of control
records: the header record,
the aforementioned optional
placeable record,and
finished by anend of

available for GIFs. It also
retainsbackward

files arewidely used for web
graphics, because they are
limited to only 256 colors,
can allow for transparency,
and can be animated. GIF

Excellent choice for both

better compression than PNG

higher color depths,
animated frames,
transparency etc.

Microsoft for Windows. There
is no compression or

files which allow images to
have very high quality, but
also very large file sizes.
