Image Tests

Image tests specify restrictions applying to an entire image. The following can be tested:

• The TIFF data starts with a TIFF header
• The TIFF data byte order is little or big endian
• The TIFF image file directory structure
• The TIFF fields appear in ascending tag order
• The TIFF data contains a single image (page)
• The TIFF header and the first image file directory reference no TIFF data from more than one place
• The G4 compressed data is valid
• The TIFF image length matches the number of G4 compressed scan lines
• The G4 compressed bilevel images have a properly placed end of facsimile block (EOFB) bit sequence
