1 = The 0th row represents the visual top of the image, and the 0th column represents
the visual left-hand side.
2 = The 0th row represents the visual top of the image, and the 0th column represents
the visual right-hand side.

sents the visual right-hand side.

sents the visual left-hand side.

Default is 1.
Support for orientations other than 1 is not a Baseline TIFF requirement.

It is not mandatory that the image be actually displayed or printed at the size implied
by this parameter. It is up to the application to use this information as it wishes.
No default. See also YResolution, ResolutionUnit

*ResolutionUnit (The unit of measurement for XResolution and YResolution)
 
Tag = 296 (128.H)
 
Type = SHORT
 
N= 1
 
<small>
<pre>
To be used with XResolution and YResolution.
1 = No absolute unit of measurement. Used for images that may have a non-square
aspect ratio, but no meaningful absolute dimensions.
The drawback of ResolutionUnit=1 is that different applications will import the image
at different sizes. Even if the decision is arbitrary, it might be better to use dots per
inch or dots per centimeter, and to pick XResolution and YResolution so that the
aspect ratio is correct and the maximum dimension of the image is about four inches
(the “four” is arbitrary.)
2 = Inch.
3 = Centimeter.
Default is 2.

*DateTime (Date and time of image creation)
 
Tag = 306 (132.H)
 
Type = ASCII
 
N= 20
 
<small>
<pre>
The format is: “YYYY:MM:DD HH:MM:SS”, with hours like those on a 24-hour
clock, and one space character between the date and the time. The length of the
string, including the terminating NUL, is 20 bytes.

luminance samples)
