4. An image is any
visual object that's
modified or altered
by a computer or an
imaginary object
created using a
computer.
5. Photo or photograph is
anything taken by
a camera, digital
camera, or photocopier.
6. Picture is a drawing,
painting, or artwork
created on a computer.
7. There are other visual objects created on a
computer that may fall into its own category, such
as clip art, graphic, illustration, render, and
a screenshot.
When talking about any of these, we suggest using
the proper terms instead of image, photo, or
picture. In other words, if you're working with clip
art, call it clip art instead of a picture.
8. An image/picture/photo
can be in printed and
digital copy.
Digital copies are those that was created
or copied and stored in electronic form.
10. An image
can also be
described in
terms
of vector
graphics or
raster
graphics.
11. Raster Image
Raster (or bitmap) images
are generally what you think
about when thinking of
images. These are the types
of images that are produced
when scanning or
photographing an object.
12. Raster images are compiled using pixels, or tiny
dots, containing unique color and tonal information
that come together to create the image. Since
raster images are pixel based, they are resolution
dependent.
13. The number of pixels that make up
an image as well as how many of
those pixels are displayed per inch,
both determine the quality of an
image.
As you may have guessed, the
more pixels in the image and the
higher the resolution is, the higher
quality the image will be.
14. Vector Image
Vector images, or line art,
keep track of points and the
equations for the lines that
connect them. Generally
speaking, vector images are
made up of paths or line art
that can infinitely scalable
because they work based on
algorithms rather than pixels.
15. One of the greatest things about vector images is
that you can re-size them infinitely larger or
smaller, and they will still print out just as clearly,
with no increase (or decrease) in file size.
16. Modern typography is
almost exclusively created
using vectors. The text
you’re looking at right now
is a product of vector
graphics.
3D modeling and the
computer graphics (CG)
we see in blockbuster
superhero films are the
direct consequence of
developments in vector art
and illustration.
21. SVG

JPEG
Joint

image
.jpg, .jpeg,
.jfif, .pjpeg,
.pjp
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
Graphics
.svg
Vector image format; ideal
for user interface elements,
icons, diagrams, etc., that
must be drawn accurately at
different sizes.
22. WMF
Vector Image Raster Image
PNG
Portable
Network
Graphics
.png
are a 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.
Windows
Metafile
.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 an end of
file record.
23. EPS

APNG
Animated
Portable
Network
Graphics
.apng
is a file format which extends
the Portable Network
Graphics (PNG) specification
to permit animated images
that work similarly to
animated GIF files, while
supporting 24-bit images
and 8-bit transparency not
available for GIFs. It also
retains backward
compatibility with non-
animated PNG files.
Encapsulat

PostScript
.eps
file is a common vector file
type. EPS files can be opened
in many illustration
applications such as Adobe
Illustrator or CorelDRAW.
24. PDF

GIF

Format
.gif
files are widely used for web
graphics, because they are
limited to only 256 colors,
can allow for transparency,
and can be animated. GIF
files are typically small is size
and are very portable.
Portable
Document
Format
.pdf
standardized as ISO 32000,
is a file format developed
by Adobe in 1992 to
present documents, including
text formatting and images,
in a manner independent
of application
software, hardware,
and operating systems.
25. CDR

WebP
Web Picture
format
.webp
Excellent choice for both
images and animated
images. WebP offers much
better compression than PNG
or JPEG with support for
higher color depths,
animated frames,
transparency etc.
CorelDRAW
.cdr
is a vector graphics
editor developed and
marketed by Corel
Corporation. It is also the
name of the Corel graphics
suite, which includes
the bitmap-image editor Corel
Photo-Paint as well as other
graphics-related programs
26. AI
Vector Image Raster Image
BMP
Bitmap
Image
.bmp
is a format developed by
Microsoft for Windows. There
is no compression or
information loss with BMP
files which allow images to
have very high quality, but
also very large file sizes.
Adobe
Illustrator
Artwork
.ai
is a proprietary file
format developed by Adobe
Systems for representing
single-page vector-based
drawings in either
the EPS or PDF formats.
