Not, if you provided some explanation. ;)

Anyway, I realized that it is not possible to have sub-pixel antialiasing 
with the RGBA images, simply because it needs separate alpha channel for
every color. 

In a result I made it first to convert the RGB glyph to grayscale and 
then to blend it to the background. This way, the transparency is always OK.

Although, using separate alpha channels the problem is solvable. 
I mean 48bit RGBrgb format instead of 32bit RGBA. (r, g and b are the alpha 
channels for
the respective color channel).

But the big question is "Do I need subpixel antialiased fonts so badly?" :)
