Security: Malformed: Bad Bluecurve

The encoding of gamma in the ICC specification permits values in the range 0-256. A gamma of zero will in effect result in all output from that channel having a maximum value.

The profile bad-bluecurve.icc has a gamma value of zero in the bTRC tag (the blue channel tone reproduction curve).

This profile can be used to test that a CMM or application can handle an encoded gamma value at the minimum of the permitted range.
