Raster images, aka bitmaps, specify the colour of every pixel. Vector images specify the lines on the image and how to colour the image. This is usually much less information. Straight lines only need the start and end points, curved lines need twice that if they are bezier curves but that's still not a lot. Colouring is basically an instruction to flood fill a colour at a specific point, although you can also do various shading patterns. None of these take up much space though.

What is the download speed of a vector image?
vector graphics as smaller than raster graphics but the size depends on the size of the image but they are generally smaller in size than raster images(i.e images such as photos) and can scale up and down without losing quality.
Images of three types and what therefore?
Three types of images are raster images, vector images, and vectorized raster images. Raster images are made up of pixels, while vector images are made up of paths and can be scaled without losing quality. Vectorized raster images are raster images that have been converted into vectors, combining the best of both worlds.
What are the two types of images?
Vector and Raster or pixel images.
Does Vector images use pixel?
No. Raster images define images with pixels. But Vector images paint the pixels on your screen!
Is illustrator raster based?
Illustrator is a vector based program that can export raster images.
What is the differeance between Rasta and vector?
Raster images are defined in pixels. ie At every x,y location, whether it is black or white. Vector images are defined by lines. eg From x,y to X,Y. Any pixel that lies between these points on a white background becomes black. It is easier to convert Vector images to Raster images, rather than the other way. Vector images are sometimes smaller (in data size). eg If the image contains one line, then the amount of data needed to store this is smaller than having to define every pixel in the image regardless of whether it is relevant. Vector images can be scaled smaller and larger without any significant loss of detail. Raster images that have been made smaller lose clarity and cannot then be made larger to improve the quality.
What are the two categories of graphic image files?
One possible categorization is in raster images and vector images.
What are the best computer drawing programs available?
Photoshop for raster images. Illustrator for vector images. These are the industry standards.
Is pdf raster or vector based?
Yes, partially. PDF encodes fonts and EPS graphics that are vector based. It also encodes images, in JPG format for example, which are raster based.
What is Vector tracing?
Vector tracing, also known as vectorization, is the process of converting raster images or bitmap graphics into vector graphics. Raster images are composed of a grid of pixels, where each pixel contains color information, and they are resolution-dependent. This means that when you enlarge a raster image, the pixels become visible, resulting in a loss of quality and a pixelated appearance.
How are GIF images stored?
As raster images, so if you have vector objects and choose to save as gif, you will not be able to change vector objects next time you open image.
Which graphical images are used on the web?
They can be either - animated or static - vector or raster images The formats tend to be .jpg, .png, and .gif.
