    Thanks !
    But what is the license ? We need a GNU GPL compatible license)

    Alain

    PS: do you have few test cases ? (please consider examples in testsuite/ (in the CVS))

    I've added some licence details, and fixed an issue with the percent keyword. Also included a plotting example in the examples section.

    I'll hopefully have a few test cases in the next week or so.

    Cheers

    I've uploaded a test case for the equalisation process of the hist_equal function. It basically tests for the shape and flatness of a distribution.

    I haven't been able to come up with a test case for the linear percent contrasting. The tails of the scaled histogram are (as expected) peaked, but trying to quantify the amount seems a little more problematic. I will look into it further, and if anyone else has any ideas/suggestions please put forward.

    Anyway hope the attached file is ok for a basic functionality test.
