Hello Christian,
Thanks for your guidance! I took a look at semantic_at_c() and get_color()
and they seem to do the trick!
Here's a couple of more questions. I've posted a compiling, annotated code
at
http://boost.codepad.org/Fy2vP73l
Below is the more elaborate description of my questions which can be found
in the code:
1. Can I specify which channel to get in nth_channel_view()? For example, if
I want to set the red channel to 255 for all the pixels, I would do
gil::fil_pixels(gil::nth_channel_view(view, 0), 255). However, that only
works if our view is rgb8 or bgr8, not argb8. Is there a way I can say
something like gil::fill_pixels(gil::nth_channel_view(view,
gil::find_channel_for_view(view, gil::red_t())), 255) ???
2. This compiles
gil::gil_function_requires
