bitmap vs vector

BITMAP

what? - A raster image made of pixels on a grid. Bitmap images are dependent on resolution and when printing bitmap images your printer needs much more image data. Most bitmap image formats include GIF, JPEG, JPG, PNG, TIFF and PSD

pros - Bitmap files can be easily created from existing pixel data, getting pixel data stored in a bitmap file is quick and easy and is accomplished using a set of coordinates

cons - Bitmap files can be very large and in order to compress the data must be expanded before hand which can slow down the reading and rendering process significantly more. They do not scale very well.

assess - Bitmaps may be better than Vectors in some cases as bitmap files are easily created while vectors are not. However Bitmaps lose quality when compressed and vectors dont.

compare - In my opinion Vectors are better than Bitmaps because they can be easily manipulated, rendered and modified with ease to suit users and not use quality whereas a bitmap would. Bitmap files are also larger than vector files however Bitmaps are easily created using data and vectors take longer.


VECTOR

what? - Vector images are made of individual scale-able object - mostly lines, curves and shapes.

pros - vectors are useful for storing images composed of line based elements. Vectors can be easily scales and manipulated. can be modified with ease and is usually easy to be rendered and save in a bitmap file format.

cons - some vector files cannot easily be used to store extremely complex images. appearance of vectors can vary considerably.

assess - Vectors are more advantageous than Bitmaps as they can be scaled and not lose quality, and can be easily rendered to a bitmap whereas bitmaps aren't easily rendered to vectors.

compare - In my opinion Vectors are better than Bitmaps because they can be easily manipulated, rendered and modified with ease to suit users and not use quality whereas a bitmap would. Bitmap files are also larger than vector files however Bitmaps are easily created using data and vectors take longer.
