If I'm not wrong for tiff we need to check [1]:
(next to fix another bug, we show only the firs page)
PageNumber. SHORT/SHORT. This tag specifies the page numbers in the fax document. 
The tag comprises two SHORT values: the first value is the page number, 
the second is the total number of pages. Single- page documents therefore use 00000001 hex.

ResolutionUnit = 2,3. SHORT. The units of measure for resolution:
2 = Inch
3 = Centimeter

XResolution = 204 (inches). RATIONAL. The horizontal resolution 
of the image expressed in pixels per resolution unit.
YResolution = 98, 196 (inches). RATIONAL. The vertical resolution 
of the image expressed in pixels per resolution unit. check
