How does the ERDAS IMAGINE Image Metadata tool handle 12-bit TIFF data?

Question

How does the ERDAS IMAGINE Image Metadata tool handle 12-bit TIFF data? When a 12-bit TIFF image file is opened in the ERDAS IMAGINE Image Metadata tool the General tab shows the data type as 16-bit.

Answer

If a 12-bit TIFF image file is opened in the ERDAS IMAGINE Image Metadata tool the TIFF Tags section under the TIFF Info tab reports the BitsPerSample tag as 16. However, the Intergraph Packets section under the TIFF Info tab should report 12-bit data. Even though the General tab of the Image Metadata tool incorrectly reports the bit depth it should not prevent the correct use of the data.
