documentlength element

The documentlength element is present when scan resolution information
is available in the image. It contains the following parts:
- inches
- Inches contains a floating point number of inches along the horizontal length of the image.
- scorelow
- Scorelow contains a floating point number between 0 and 10 (inclusive). This value is the Image Quality Analysis estimate of the likelihood the document length is not too short. A 10 indicates the length passes this test and is good. A 0 indicates the length fails this test and is too short. Values in between 0 and 10 indicate the document length is marginal and may be too short.
- scorehigh
- Scorehigh contains a floating point number between 0 and 10 (inclusive). This value is the Image Quality Analysis estimate of the likelihood the document length is not too long. A 10 indicates the length passes this test and is good. A 0 indicates the length fails this test and is too long. Values in between 0 and 10 indicate the document length is marginal and may be too long.
