2. L.I. 1.I will learn about Vector and Raster graphics 2.I will learn about the advantages and disadvantages of both types of graphics 3.I will learn about the common file formats used for each Success Criteria Success Criteria 1. I will UNDERSTAND the difference between the two types of graphics 2. I will REMEMBER the different file formats used for each graphic type Social Skill 1. I will listen carefully to my partner/classmates

3. Vector images are mathematical calculations from one point to another that form geometrical shapes. Raster (bitmap) images are made of pixels. A pixel is a single point or the smallest single element in a display device.

4. Vector graphics are scalable - ie when you resize them, they do not lose quality. When you take a photograph using a digital camera or scan an image from a magazine, you are creating a raster (bitmap) graphic.

6. An image which is made up of tiny squares of colour. The arrangement of these tiny coloured squares produce the effect of an image. This is a good method of reproducing 'continuous tone' images, such as photographs. Raster/bitmap graphics

7. cannot be scaled up without losing quality. Why? Is bound by the number of pixels in the image. Large dimensions & detailed images equal large file size. Raster/bitmap graphics Some service providers like engravers, stencil-cut signs, etc, must have vector art. It is more difficult to print raster images using a limited amount of spot colours. Depending on the complexity of the image, conversion to vector may be time consuming.

8. can be scaled up without losing quality. Why? Made of mathematical calculations that form objects and lines. a small file size They are ideal for logo designs, as they can be printed very small on business cards or printed large on a billboard poster. Vector graphics business cards

9. Vector graphics It is not the best format for photographs or photo-like elements with blends of colour.
