HA1 - Technical File – RASTER AND VECTOR IMAGES
RASTA IMAGES- a raster graphics image, is a an representing a generally shaped
grid of minor pixels and points of colour viewable on sheet via screen etc. Raster
images are stored in files with varying formats such as jpeg pdf etc. Raster images is
made by digital image capture devices/digital scanners or digital cameras, or by pixel
editing programs. Raster images are composed of a matrix grid of digital picture
elements. Pixels are squares or rectangles described as black, white, gray or RGB.
Raster images typically are saved as TIFF format, but can be saved as EPS as well.
Vector images exchange. Vector graphics typically are saved as EPS format. typically
are generated using drawing or illustration programs Adobe Illustrator and are
composed of mathematically-defined geometric shapes lines objects and fills. Since
vectors entail both magnitude and direction vector elements are comprised of line
segments whose length represents magnitude and whose orientation in space
represents direction
Look at the picture difference when in zoom.

4. Antialiasing
Antialiasing is a technique in computer
graphics where you can smooth Images
that have unfinished smudges at the end
of it image so this software Technique
would make the appearance of the image
a whole lot better.
EXAMPLES:
5. Resolution
Low resolution
Resolution image is used for a pixel count
in digital imaging. Resolution is a very important
In the media industry of photography because
What it basically means is of every picture you
Have taken it always be measured on length and
Height basically the meaning of resolution is
Length and height measurements of the image.
High resolution
6. Aspect ratio:
You can easily tell what it means by
looking at the word ratio
And the topic we are looking at which is
images it basically means The size length and
width and height of an image the are the
Measurements that are looked at through each of the
Images.
In this picture you can see the Different
shape and sizes of Each television you
can easily See the difference because
This is an aspect ratio of each sizes Each of them are bigger and Wider than
of prints and monitors. each one .
Basically what aspect ratio is
(as i mentioned in the paragraph above)
Measurements in and around the photograph.
7. File Formats The different types of file formats
In digital printing are...
JPEG, TIFF, GIF, PSD, PDF, EPS.
The use of JPEG is to create an existing work into one image page
The use of TIFF contains layers that can be attached to an image file for Rasta and
Vector images and produced into a high quality image.
GIF supports images only up to 8 megapixels which allows images reference a palette
Up to 256 distinct colors.
Basically what PSD is a software that would support images to a high megapixels and
Resolution.
PDF is a file that you can save any image or work document and then can be reopened
Into a software for example illustrator Photoshop.
EPS is a file that contains 2d vector graphics , bitmap images and text it also includes
Embedded images.
8. Color Models
The different types of color models are RGB color and CIE color.
RGB – The RGB color mode is where the primary colours are mixed together and
the difference between this and CMYK is cmyk have different colours in its
mode witch an be useful in printing operations
CMYK- cmyk stands for four color printing and those colours are cyan, magenta,
Yellow and black. CMYK is also useful when masking colours on light white background
Can you see the colour difference
between the two diagrams
9. Adobe Photoshop
• A popular high-end image editor for the Macintosh and Windows from Adobe. The
original Mac versions were the first to bring affordable image editing down to the
personal computer level in the late 1980s. Since then, Photoshop has become the
de facto standard in image editing. Although it contains a large variety of image
editing features, one of Photoshop's most powerful capabilities is layers, which
allows images to be rearranged under and over each other for placement.
Photoshop is designed to read from and convert to a raft of graphics formats, but
uses its own native format for layers
10. Adobe illustrator
Adobe Illustrator is a vector graphics editor developed and marketed by Adobe
symptoms Illustrator is similar in scope, intended market, and functionality to its
competitors, Corel draw, Xara designer pro and Macromedia free hand are The
latest version, Illustrator CS5, is the fifteenth generation in the product line
11. Adobe in design

used to create works such as posters, flyers, brochures, magazines, newspapers
and books. InDesign can also publish content suitable for tablet devices in
conjunction with Adobe Digital Publishing Suite. Graphic designers and production
artists are the principal users, creating and laying out periodical publications,
posters, and print media. It also supports export to EPUB and SWF formats to
create digital publications, on the other hand it Integrate interactivity, video, and
