Hi, Thank you for that fast response. Lubomir Bourdev <lbourdev@adobe.com> wrote:

Now I get another compiler errror at pixel_iterator_traits.hpp:128: gil/core/pixel_iterator_traits.hpp|128| error: no type named 'channel_t' in 'struct gil::default_color_converter' gil/core/pixel_iterator_traits.hpp|129| error: no type named 'color_space_t' in 'struct gil::default_color_converter' A few pages later there are more error messages about pixel_traits being instantiated with gil::default_color_converter. There several other types of default_color_converter are accessed. Regards Andreas Pokorny
