What is the difference between Vector Art and Raster/Bitmapped Art?
Vector Art images are created by mathematical formula. The art is constructed of points, lines, curves and shapes that are scalable to any size without losing clarity. Vector graphics are created in drawing programs such as Adobe Illustrator and CorelDraw. These images are very flexible to work with.
Raster Art (Bitmapped) images are pixel based and consist of rows of and columns of dots. Raster art is created by scanning a document or image. Photographs and graphics created in software programs such as MS Paint, Corel PhotoPaint and Adobe PhotoShop are raster images. Raster graphics can become distorted, ragged and blurry when reduced or enlarged. They are NOT very flexible to work with.
Resolution: This is the density of the dots in a raster image file, also known as DPI (dots per inch) or PPI (pixels per inch). Sharpness and clarity of a raster image is determined by and refered to as the resolution of the image. What looks sharp on a computer or mobile device screen may not always give you a sharp image when printed. To look good on a device screen an image only needs a resolution of 72 DPI. For large format printing, a minimum resolution of 300 DPI is required for an image to look sharp.
