Bitmap

Bitmap refers to a type of digital image composed of a matrix of individual pixels (picture elements), where each pixel holds color information. The term is often used interchangeably with raster image. In a bitmap image, the resolution is fixed, meaning that scaling the image up or down can result in a loss of quality or pixelation.

Key Characteristics of Bitmap Images:

• Pixel-based: Each image is made up of a grid of pixels.
• Resolution-dependent: Quality is tied to the image's resolution (e.g., 300 DPI).
• File formats: Common bitmap formats include BMP, JPEG, PNG, GIF, and TIFF.
• Best for: Photographs and detailed images with complex color variations.

Common Uses:

• Digital photography
• Web graphics
• Print media (when high resolution is maintained)

In contrast to vector graphics, which use mathematical formulas to define shapes and lines, bitmap images are better suited for rich, detailed visuals but are less flexible when it comes to scaling.
