Examples

• The photograph was saved as a bitmap file rather than a vector format.
• Bitmap images can lose quality when enlarged because they are made of fixed pixels.
• The designer converted the logo from a bitmap to a vector graphic for better scalability.
• A bitmap is useful for storing complex photographic images with many colors.
• The database uses a bitmap index to quickly check which records match certain criteria.
• Unlike vector graphics, bitmaps require more storage space for high-resolution images.
