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 |
