Unit 30 P2


Graphic type
Describe how the graphic is constructed and why you chose the graphic type
How will the final file be saved?
Internet graphic
 Bitmap
When a photo is taken on a Digital camera or when an image is scanned from a magazine a bitmap graphic is created. A bitmap is made out of tiny parts these are called pixels, they usually come in all different colours. You can edit a bitmap and also edit every individual pixel. This is because a computer has stored information about every pixel in the image. A bitmap graphic is usually quite large. However when you change the size of a bitmap graphic the image becomes distorted meaning the graphic loses quality.
 Jpeg, Gif or Png
Van sign graphic
 Vector
 A Vector graphic is created in graphic packages. But unlike bitmap they consist of shapes called objects. You can edit each object individually by shape size and colour. Even though a vector can be quite large it does not need much memory to be stored. Therefore the file size of a vector is usually small. They are also scalable meaning when you change the size of them they do not lose quality.
 EPS, AL, PDF, SVG or DXF
Brochure
 Writing-Vector
Pictures-Bitmap
 You would use both vector and bitmap. Bitmap for pictures because you would want them to look more lifelike. Whereas a vector would be better for writing because it will stay clear making it easier to read.

  1. www. P2, Well done. Here you have explained the features and limitations of different file formats, drawing conclusions regarding which formats lend themselves to particular graphical products. This is exactly what was asked for.
