Advanced Scanning
| black and white line art requires only |
| 1 bit per pixel. |
| Scanning an original as a color |
| image requires three times the |
| storage as scanning it as a grayscale |
| image, and 24 times the storage |
| requirement of a black and white line |
| art image. |
Size | What are the dimensions of the |
| original? Scanning a 2" x 2" original |
| creates a smaller file than scanning |
| an 8" x 10" original. |
Scaling | Scaling (enlarging or reducing) an |
| image changes the file size |
| accordingly. For example, scanning |
| an image you scaled to 150% of its |
| original size requires 50% more |
| storage than if you had scanned it at |
| 100% (no scaling). |
Resolution | Resolution is the amount of detail |
| that shows in an image, measured by |
| the number of dots per inch (dpi). |
