Hey cool. Glad to hear you had no problems.
Sorry, I missed it. I had an early night last night (sunday night >_<)
.. Are there recordings to review?
There is indeed!
I'll be streaming again tonight FYI.
It's an interesting idea; knowing if a colour is convertible to some
other colour without loss... it sounds like it leads to implicit
conversion, but I don't think we want that here.
I'll think on how to do it. It's not really trivial.
It shouldn't be implicit. Never implicit. Always must be asked for.
I just want functions to tell me if it is loosing or gaining precision
in the conversion. That way it can be e.g. logged.

Why would IImage support alpha? Shouldn't that be on the color?
If so, the PR does support it see RGBA8 and friends.
I said "on color or IImage". Anyway transparency is a property (mask) of
an image ("material") rather than of the color itself. A color has no
transparency, there's no transparency on gamut. It doesn't make sense
for a color: transparency is used only when you add an image over
another in order to sum the *colors* of two pixels. They used to pack
alpha informations with other pixel infos (color) just for simplicity
and to have a convenient way to store info inside a file, I guess.
I just had a look at antigrain. It really is beyond this code. Well
and truly out of scope.
I mean it would be useful to grab some ideas from it.
And that it would really wonderful to have something like this.
However I think it is useful to build the library and interfaces
thinking also to possible future developments.

Humm, I can add it as an optional part of the interface like pixel offset.
Maybe. But it does feel a little less like other libraries out there.
The main reason I'm put off of antigrain is it feels a little too much
unwieldy to me.
But of course, I can't dismiss your guys suggestions so of course I'll dig
more deeper into it! Even if I do drag my heels a little bit.
