This document discusses digital graphics technology, specifically comparing bitmap and vector images. Bitmap images are composed of pixels and store color data for each pixel, so bitmap files tend to be large in size. Vector images use geometric primitives like points, lines, and curves defined by mathematical equations, allowing them to scale smoothly. The document outlines advantages and disadvantages of each format, such as bitmaps being easier to create but larger in size, while vectors can scale smoothly but have limited editing capabilities. Programs like Photoshop, Illustrator, and CorelDRAW are used to create and edit different image types. Factors like output method and compression also impact image quality.

Introduction
In this report I will be talking about digital graphic images and how
they work, and introduce what bitmap image does and what vector
image and talk about how they both made, how they are used, what
they are used for. This report will feature all that.
Digital graphics technology
Digital graphics technology makes the games look more real and
adventures forpeople to play and that’s why many people prefer to
play games that are digital graphic because people can connect to
the game and feel like they are there.
Bitmap
Bitmap graphic is when you take a picture with digital camera or scan
it from a magazine, that’s creating a bitmap graphic image.
How are they made? Bitmap graphic is made out of tiny parts of
pixels, sometimes the come in different colours; you could edit each
pixel by itself.
The computer stores information about the entire pixel in the images
and the file of bitmap sometimes it’s quite large.
You would use bit map image which is computer file to store pictures
it’s made out tiny blocks called pixels.

2. Advantages and Disadvantages of bitmap
Advantages are, files are easier to be created from existing pixel data
that’s stored in memory. Also the bitmap files might translate well to
dot-format output devise such as printers. Also bitmap files are
usually made and suited for storage of red world images.
Disadvantages that they are large and if the image contains number
of colours, or data compression can shrink the size of pixel data so
that data have to be expanded before is used and it’s going to start
to slow down the reading.
Programs used to make vector images.
The common vector images are drawings, illustrations and
cartoons, the programs used to make these images are Adobe
illustrator, coral/draw and free hand.
Vector
Vector graphic is the use of geometrical primitives. Vector is made of
point’s lines and curves the image is displayed through
mathematical. Uses for vector images are printing on paper and
cloths. There commonly used vectors plasmids and virus-based
vectors.

3. Advantages of vector images
this is important point about vector image is their power of
scalability when you try enlarge a bitmap image your computer can
only enlarge the size of the square making up the image area
however the vector image remain smooth because your computer
merely re-computes the coordinates of the points and adjust the
vector equationconstants.
Disadvantage of vector images
when your drawing containing trapping information can only be
scalded up to 20% larger or smaller. Above mentioned reason the
vector graphics are not as cost effective as bitmap images.
Output
How an image will be outputted often determines the kind of image
it needs to be. Print-printing uses the colour yellow, Magneton, black
screen –uses pixels to display and image, so uses the rob colour
pallet.
Factors that affect quality
Digitally drawing on image in Photoshop with a sketchpad and styles
this image can resize, providing it is being drawn as a vector image.
Using a digital camera simply takes a photo which is saved digitally
storage as a bitmap image so will lose quality if resized. Also there
are some websites that will resize youimage for free like, pics resize,
resize your image, web resizer all these website will help you resize
your images for free. The compressing is the objective of image
compression is to reduce irrelevance and redundancy of the image
data in order to be able to store or transmit data in an efficient form.

4. Capturing images
Drawing into a computer
The advantages of drawing an image is that you can Photoshop it
with sketch pad and styles and you could always resize the image
with providing it with vector image and it won’t lose it quality like
most capturing images
Scanning image
When you scan an image that has been drawn the advantages of it
that it’s your ability of likeness and your work because you draw it
the disadvantage is that the image cannot be resized without it
losing it quality.
Taking a photograph
Taking a photograph by yourself with digital camera the advantage of
that it’s your picture which you can save it digitally and store it as a
bitmap image but the disadvantage is that when your try to resize
the picture or changing it up it loses it quality.

5. Organisation
Here are all my files and the folder is called Aki and all my media
work for that lesson is in there. This is important because you got all
your work saved in there and everything is organised and it makes it
much easier for you to find your work when it’s organised like this.

6. Conclusion
this report outlines and discuss the different methods the
advantages disadvantages of different methods of researching what
they do how they do it also I managed to put the pictures to help you
understand and show you how things work and why they work the
way they do. This report will help me on my course work by knowing
how to researching different type of information and understand the
different types of photo imaging how you take it and advantages of
things it was very knowledging to learn new things.
