CGapiSurface used as a mask Question

[me2]

CGapiSurface* mask = new CGapiSurface();
mask->CreateSurface(NULL,width,height);

mask->FillSurface
(NULL,RGB(0,alpha,0),NULL,NULL);


MyQuestion:
How much memory will be allocated for the mask?
size of (RGB)*width*height or
sizeof(G)*widht*height?
(the R and B component are 0)

Note that keeping memory only the G component of the surface is enough ...

Basically it could.. But all mask operations would have to be modified. It also would mean very little performance gain.

So, shall we see it in the next version of GapiDraw?

I think that is worth to implement ...
or maybe implement a new CGapiMaskSurface class that would be memory optimized and some drawing methods using it ...
I prefer the first option
Of course, as you said, there would be other thing that would need touch ...
