image files

• What are the two types of digital static images?

  Bitmap and vector images
• How do bitmap images form a complete picture?

  They consist of individual color pixels in a grid
• What does zooming into a bitmap image reveal?

  Distinct color pixels
• How are colors stored in bitmap images?

  As numbers defined by RGB values
• What is the primary difference between bitmap and vector images?

  Bitmap uses pixels; vector uses coordinates
• What happens when you resize a bitmap image?

  It may appear pixelated
• What advantage do vector images have when resizing?

  They can be resized without quality loss
• What limitation do vector images have compared to bitmap images?

  They cannot store complex color variations
• What does pixel dimensions refer to?

  The size of the pixel grid
• How does higher pixel dimensions affect image quality?

  It usually means better quality
• What is the relationship between pixel dimensions and file size?

  Larger dimensions lead to larger file sizes
• What do DPI and PPI measure?

  Dots per inch and pixels per inch
• Which resolution is common for printing?

  DPI (dots per inch)
• How does PPI affect image quality on screens?

  It impacts quality more than pixel dimensions
• Why does an 800 by 600 pixel image appear lower quality on a 52-inch screen?

  Lower pixels per inch on larger screen
• What are common bitmap formats?

  Tiff, JPEG, GIF, and PNG
• What is Tiff format used for?

  High quality printing and scanning
• What is a drawback of Tiff format?

  It has larger file sizes
• What is JPEG format best suited for?

  Online photography and lower quality printing
• What is a limitation of JPEG format?

  It loses image quality during compression
• What is GIF format used for?

  Simple web graphics and animations
• What is a limitation of GIF format?

  It is limited to 256 colors
• What is PNG format used for?

  High quality images requiring transparency
• What is a drawback of PNG format?

  It compresses less effectively than JPEG
• What are common vector formats?

  SVG, EPS, and PDF
• What is SVG format used for?

  Web graphics with smaller file sizes
• What is a limitation of SVG format?

  Not optimized for large-scale printing
• What is EPS format known for?

  High compatibility with graphic design software
• What is a drawback of EPS format?

  It has poor compression capabilities
• What is PDF format used for?

  Printing and web document display
• What is a benefit of PDF format?

  Ensures consistent display across devices
• What is a limitation of PDF images?

  Cannot be directly edited
• What are the key considerations when working with images?

  • Understand differences between bitmap and vector images
  • Consider pixel dimensions and resolution
  • Choose the appropriate file format
• What is the main purpose of understanding image properties and formats?

  To optimize image quality and file size
