Re: [boost] [GIL] Pixel Layout Padding?

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 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, to something like pixel.

Then we can specify RGBX as pixel, or XRGB as pixel where minus means left justify.

Sorry, I mean RGBX as pixel; XRGB as pixel, apparently I'm confused by myself :p

...

Ideas?
