[][src]Constant xcb::xproto::GC_PLANE_MASK

pub const GC_PLANE_MASK: Gc

In graphics operations, given a source and destination pixel, the result is computed bitwise on corresponding bits of the pixels; that is, a Boolean operation is performed in each bit plane. The plane-mask restricts the operation to a subset of planes, so the result is:

    ((src FUNC dst) AND plane-mask) OR (dst AND (NOT plane-mask))
