RESOLUTION: VECTOR VS. PIXEL

There are two types of images: Bitmaps which are pixel based, and Vectors which are based on mathematical functions. The sharpness of a Bitmap image is expressed in ppi—pixels per inch; the higher the ppi, the sharper the image. A Vector keeps the same sharp quality regardless of its size. Bitmaps are resolution dependent and Vectors are resolution independent.

 ---------

Resolution Dependent
Bitmap -- When you resize a bitmap, what you’re actually doing is changing how many pixels occupy an inch. Significant resizing decreases the quality  of an image, making it look “pixelated.”

Resolution Independent
Vector -- When you resize a vector, the software recalculates and redraws the artwork which allows the image to maintain the same sharp quality regardless of its size.

Adobe Photoshop = Resolution Dependent

Best uses: Photo manipulation | Illustration

Adobe Illustrator = Resolution Independent

Best uses: Logos | Graphics

Mechanics of a Vector

Anchor points define the start and end point of the curve.

Handles manipulate the slope of the curve.

Path is another word to describe the Bézier curve.

Fun Fact: While the mechanics behind Bézier curves have been known since the 1920s, French Engineer Pierre Bézier made the application of these curves more widely known in the 60s, which is why they are called Bézier curves.
