Bitmap images use a grid of pixels to represent an image, with each pixel having its own color. Vector images use mathematical relationships between points and paths to describe an image. Bitmaps are resolution dependent and lose quality when resized, while vectors are scalable and resolution independent. Bitmaps are better for photos while vectors work well for illustrations and logos.

1. Computer Graphics
Bitmap Images VS. Vector Images
By Zoe Chang

2. Bitmap VS. Vector
Bitmap Image:
A bitmap image uses a grid of
individual pixels where each pixel
can be a different color or shade.
Bitmaps are composed of
pixels.
Vector Image:
Vector graphics use
mathematical relationships
between points and the paths
connecting them to describe an
image. Vector graphics are
composed of paths.

3. Characteristics
Bitmap:
• pixels in a grid
• resolution dependent
• resizing reduces quality
• easily converted
• restricted to rectangle
• minimal support for
transparency
Vector:
• scalable
• resolution independent
• no background
• cartoon-like
• inappropriate for photo-
realistic images
• metafiles contain both
raster and vector data
