A bitmap or bit map is an image representation made up of a grid of pixels. Digital photographs are an example of rasterized images. Their detail depends on resolution, compression, and display size.
How is a bitmap image represented?
Each pixel provides color information. When you enlarge an image beyond its useful resolution, detail limitations can become visible. Choosing a format and dimensions requires considering use and file size.
How is it applied in marketing?
A photograph for a glossary card is prepared with sufficient dimensions and appropriate compression. The goal is to maintain visual legibility without delivering an unnecessarily heavy file.

Frequently asked questions about bitmap
Does bitmap always mean BMP file?
No. Bitmap describes a representation; BMP is a specific format. Other formats also contain rasterized images.
Is a photograph rasterized?
It is usually represented using pixels. Its quality depends on capture, resolution, and processing.
What happens when you enlarge it too much?
Edges or limited detail may appear. Changing dimensions does not automatically recover nonexistent information.
What format is suitable for web?
It depends on content, transparency, and compatibility. Evaluate quality and file size for the intended use.
When is a vector advisable?
For shapes that need to scale sharply, such as certain graphics and logos, if you have a suitable original.
Bitmap: limits you should know
A rasterized image does not gain real detail by enlarging it. A vector represents shapes differently and responds better to certain uses, such as logos.
