Struct AllocColorRequest

pub struct AllocColorRequest {
    pub cmap: u32,
    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.

Fields

• cmap - TODO
• red - The red value of your color.
• green - The green value of your color.
• blue - The blue value of your color.

Errors

• Colormap - The specified colormap cmap does not exist.

Fields

cmap: u32

red: u16

green: u16

blue: u16
