Adobe Illustrator Creates Vector Graphics – Comparing Raster and Vector Images

Adobe Illustrator creates Vector graphics, which are made from mathematically precise lines and curves.  Even when hugely enlarged, Vector images remain sharp.  On the other hand, Photoshop’s images are Raster images.  They are  pixel-based; and enlarging them, saving and re-saving them, etc., cause Photoshop’s images to loose image quality.

“Why use Adobe  Illustrator?  – Vector graphics {sometimes called vector shapes or vector objects) are made up of lines and curves defined by mathematical objects called vectors, which describe an image according to its geometric characteristics….

“You can freely move or modify vector graphics without losing detail or clarity, because they are resolution-independent–they maintain crisp edges when resized, printed to a PostScript printed, saved in a PDF file, or imported into a vector-based graphics application.  As a result, vector graphics are the best choice for artwork, such as logos, that will be used at various sizes and in various output media.

“The vector objects you create using the drawing and shape tools in Adobe Illustrator and the Adobe Creative Suite are examples of  vector graphics.” Adobe Illustrator CS6 Classroom in a Book, p. 35
