Bitmap images use a grid of pixels to represent an image, with each pixel storing a color value. Bitmaps are resolution dependent and quality degrades with resizing. Vector images use mathematical relationships between points and paths to represent shapes, allowing the images to be resolution independent and scalable without quality loss. Key differences between the two formats are that bitmaps are best for photo-realistic images while vectors are more suitable for illustrations and logos due to their scalability.

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
