compressed element

The compressed element in Figure 1 is always present. It contains the following parts:

bytes

Bytes contains the integer number of bytes in the compressed image data, including the image wrapper.

scorelow

Scorelow contains a floating point number between 0 and 10 (inclusive). This value is the Image Compliance estimate of the likelihood the compressed image data is not too small. A 10 indicates the compressed size passes this test and is good. A 0 indicates the compressed size fails this test and is too small. Values in between 0 and 10 indicate the compressed image size is marginal and may be too small.

scorehigh

Scorehigh contains a floating point number between 0 and 10 (inclusive). This value is the Image Compliance estimate of the likelihood the compressed image data is not too large. A 10 indicates the compressed size passes this test and is good. A 0 indicates the compressed size fails this test and is too large. Values in between 0 and 10 indicate the compressed image size is marginal and may be too large.
