7.4.2 WinSPM image file
Although WinSPM image files are based on the standard TIFF, the structure of WinSPM
TIFF files is partly different from the standard TIFF file structure.
7.4.2a Overall
structure
of WinSPM image file

Etc.
The data address and file size depend on the kind of image data. In principle,
however, the WinSPM image file is compliant with the structure shown above.

Image Header
As can be seen from the above illustration, in WinSPM, Image Header is inserted
between Header and Directory. This file area contains information on measurement
conditions in SPM measurement. Refer to 7.4.2

data structure.
