Hi Christian, Thank for your reply, but I continued to investigate on my problem and in fact I found the problem. The function color_converted_view only process pixel if they are differents which is not our case, we want to process every time. To change that, I copy the code from GIL and modify what I wan't to process every times ( https://github.com/tuttleofx/TuttleOFX/blob/develop/libraries/terry/src/terr...), which correct my problem.

Hi Marc,

are you aware of scoped_channel_value? Here a small example:

// Create a double channel with range [-0.5 .. 0.5] struct double_minus_half { static double apply() { return -0.5; } }; struct double_plus_half { static double apply() { return 0.5; } }; typedef scoped_channel_value bits64custom_t;

// channel_convert its maximum should map to the maximum bits64custom_t x = channel_traits::max_value(); assert(x == 0.5); bits16 y = channel_convert<bits16>(x); assert(y == 65535);

Let me know. If that doesn't help I'll dig deeper into your problem.

Regards, Christian

Hi guys,

I currently working on TuttleOFX projet, and using Boost GIL to perform some image process. I wan't using color_converted_view to process clamping values on a view, witth a specific ColorConvert (CC) functor.

But with the actual code [ https://github.com/tuttleofx/TuttleOFX/blob/master/libraries/terry/src/terry... ] , the pixel_clamp contructor was corretly called, but our functor (void operator()( const SPixel& src, DPixel& dst ) const) wasn't. Does someone have the same bug ? Are they more documentation anywhere on this function ( I'm refering on
