I tried to compile by commenting out the string CLAMP(output, 0, 1.0)<br>
in histogram.C. The compilation occurred without errors. CinGG starts<br>
without errors and the Histogram plugin runs without errors. In the<br>
graph you can see that the data in the area beyond 1.0 is not visible,<br>
however, this time the plugin seems to work in float because I was<br>
able to pull out the hdr data that was present in the original image.<br>
See attached image.<br>
Note that the normal plugin has a horizontal line between 100 and 110%<br>
(as well as between 0 and -10%). It is the clip line. That line has<br>
remained in black but is no longer there in super-white.<br>
No errors or other messages are reported in the terminal from which I ran CinGG.<br>
I will continue testing, but if all goes well I propose to remove the<br>
line from the code because having an important plugin like histogram<br>
without the clip is a good thing.<br>
