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
