Raster vs Vector Graphics Concepts

The video tutorial by Cheryl Graham explains the differences between vector and raster files in digital graphics. Raster images are pixel-based, while vector images are made of mathematically described objects. The tutorial covers the characteristics, applications, and file formats of both types, highlighting that vectors are resolution-independent and ideal for designs with flat colors and hard edges, while rasters are better for continuous tone photos. The video also demonstrates how vector graphics maintain quality at any size, unlike raster images, which can become pixelated when enlarged.

What is the primary difference between vector and raster graphics?

• Vector graphics are used for photos, while raster graphics are used for logos.

• Raster graphics are pixel-based, while vector graphics are mathematically described.

• Vector graphics are pixel-based, while raster graphics are mathematically described.

• Raster graphics are used for logos, while vector graphics are used for photos.

What are raster images made up of?

• Gradients and patterns

• Paths and strokes

• Square pixels arranged in a grid

• Mathematically described objects

Which software is commonly used to work with raster images?

• CorelDRAW

• Adobe Illustrator

• Adobe Photoshop

• Inkscape

What are vector images made up of?

• Textured backgrounds

• Square pixels arranged in a grid

• Mathematically described objects

• Continuous tone photos

Which software is commonly used to work with vector images?

• Adobe Illustrator

• Corel Painter

• GIMP

• Adobe Photoshop

Why are vector graphics considered resolution independent?

• They have a specific pixel resolution

• They are made up of pixels

• They rely on DPI for their quality

• They are mathematically described

What happens to a raster image when it is enlarged beyond its resolution?

• It changes its color

• It converts to a vector image

• It becomes fuzzy and loses quality

• It remains sharp and clear

Which type of image is better for logos and business cards?

• Vector images

• Digital paintings

• Textured backgrounds

• Raster images

What is a common file format for vector graphics?

• SVG

• JPEG

• TIFF

• PSD

Which type of image generally has a larger file size?

• Raster images

• It depends on the software used

• Vector images

• Both have the same file size
