Enumeration Type Documentation

PlaneCount

enum class epaper::internal::PlaneCount : std::uint8_t

strong

Type-safe enumeration for framebuffer plane counts.

Used internally to represent the number of color planes in a framebuffer. Different display modes require different numbers of planes:

• One: Monochrome modes (BlackWhite, Grayscale4, Spectra6)
• Two: Dual-plane color modes (BWR, BWY) where base + accent planes
• Three: Reserved for future multi-plane color modes

Enumerator
One	Single plane (monochrome or packed multi-color)
Two	Dual plane (base + accent color)
Three	Triple plane (reserved for future use)
