This table lists properties and components taken from Florida Digital Archive Action plan, TIFF 6.0 (http://actionplan.fcla.edu/), with additional notes:
| property value | component | notes |
|---|---|---|
| image width | content | measured in number of pixels |
| image height | content | measured in number of pixels |
| sequence of images | structure | If a TIFF file contains multiple images, the sequence of the images in the TIFF file will be preserved (Florida Digital Archive Action plan, TIFF 6.0) |
| X sampling frequency | appearance | may be expressed as X resolution |
| Y sampling frequency | appearance | may be expressed as Y resolution |
| samples per pixel | appearance | Typically 1 for bilevel, grayscale and palette-colour images; typically 3 for RGB images. |
| bits per sample | appearance | |
| extra samples | appearance | If samples per pixel is higher than 3 the number of extra samples is recorded in this field |
