Bitmap vs. Vector Graphics Practice Flashcards

A set of flashcards exploring the differences between bitmap and vector graphics, including their definitions, file formats, and best use cases.

What is the name of the blocky, jagged effect that happens when a bitmap image is scaled up?

Pixelation

What is a bitmap or raster image made of?

A fixed grid of tiny little squares called pixels.

Why are bitmaps considered perfect for photographs?

They can capture millions of colors and all those subtle little details and textures.

What is the primary drawback of storing information for every single pixel in a bitmap?

File sizes can get pretty huge.

What happens when a computer tries to make a bitmap image bigger?

It can only make the existing pixels bigger, which creates chunky, blurry squares.

Instead of pixels, what does a vector graphic use to solve the scaling problem?

A path.

What does it mean that a vector graphic is based on "mathematical instructions"?

The file stores formulas for drawing shapes (like a circle's center point, radius, and color) rather than a picture of those shapes.

What is the result of applying pure math to an image's size in a vector graphic?

The image is infinitely scalable and keeps perfect, crisp lines every time.

How do vector file sizes typically compare to bitmap file sizes?

Vector file sizes are usually way, way smaller.

What are two common file formats associated with bitmap graphics?

JPEGs and PNGs.

What are two common file formats associated with vector graphics?

SVG and AI.

Why is the vector format the best choice for a company logo?

It can scale to any size, from a tiny app icon to a massive billboard, while staying sharp.

Why are vector graphics used for website icons?

Their tiny file sizes help websites load fast and they stay crisp on any screen, from a phone to a $4k$ monitor.

What is the core decision-making factor when choosing between a pixel (bitmap) and a path (vector)?

Deciding whether you need realism (photographs) or scalability (logos and icons).
