I'm sure you thought of it but for now could you use RGBA? Probably not, but what would an alignment of 4 refer to? Is it size in bytes or channels? Could you describe a use case? Regards, Christian On Thu, Dec 26, 2013 at 10:21 AM, TONGARI J <tongari95@gmail.com> wrote:

Hi there,
The current gil::pixel design has a deficiency that you can't specify the align of pixel, for example, you can't have an RGBX pixel in GIL where X is padding.
An alternative is to introduce a dummy channel for X, but that doesn't seem to be a good idea as we don't want to mess up the color space.
So, maybe it'd be better to extend the current design, say, pixel<ChannelValue, Layout>, to something like pixel<ChannelValue, Layout, Align>.
Then we can specify RGBX as pixel<uint8_t, rgb_layout_t, 4>, or XRGB as pixel<uint8_t, rgb_layout_t, -4> where minus means left justify.
Sorry, I mean RGBX as pixel<uint8_t, rgb_layout_t, -4>; XRGB as pixel<uint8_t, rgb_layout_t, 4>, apparently I'm confused by myself :p
Ideas?
