Struct xcb::x::AllocColor

pub struct AllocColor {
    pub cmap: Colormap,
    pub red: u16,
    pub green: u16,
    pub blue: u16,
}

Allocate a color

Allocates a read-only colormap entry corresponding to the closest RGB value supported by the hardware. If you are using TrueColor, you can take a shortcut and directly calculate the color pixel value to avoid the round trip. But, for example, on 16-bit color setups (VNC), you can easily get the closest supported RGB value to the RGB value you are specifying.

This request replies AllocColorReply.

Associated cookie types are AllocColorCookie and AllocColorCookieUnchecked.

Fields

cmap: Colormap

TODO

red: u16

The red value of your color.

green: u16

The green value of your color.

blue: u16

The blue value of your color.
