Understand the Problem

The text in the image discusses bitmaps, their characteristics, structure, and terminology, including definitions of key terms such as pixel, resolution, and gradient. It's providing information likely for educational purposes.

Answer

A bitmap is a pixel-based image format; quality depends on resolution.

A bitmap is a digital image composed of a grid of pixels. Each pixel has a color value, and the image quality depends on the resolution, which is the number of pixels. Higher resolution offers more detail but also increases file size.

Answer for screen readers

A bitmap is a digital image composed of a grid of pixels. Each pixel has a color value, and the image quality depends on the resolution, which is the number of pixels. Higher resolution offers more detail but also increases file size.

More Information

Bitmaps are well-suited for detailed images like photographs but don't scale well compared to vector images. Their quality is directly proportional to their resolution, which affects both detail and file size.

Tips

A common mistake is to use low-resolution bitmaps for large prints, resulting in pixelation.
