Tiff header not being read completely

[Richard Cole]

Dear Group,

 

I have tiff images being generated by imagepro where the pixel size is not
being read,  any ideas why?   I have attached an example image.

 

Thanks

This is because Image Pro, like many other image processing programs,
stores the pixel information in non-standard fields in the TIFF header.
Here is the output of tiffinfo (from the libtiff package) on your exemplar.
Note the "unknown field warnings." The standard TIFF resolution is in dpi,
hence the 300, 300 entry...

Hope this helps
