Struct AndroidHardwareBufferRingDescriptor

Namespace

Maplibre.NativeFfi

Assembly

Maplibre.NativeFfi.dll

A ring of Android hardware buffers that the library allocates, for MapHandle.AttachAndroidHardwareBufferRing().

public readonly record struct AndroidHardwareBufferRingDescriptor : IEquatable<AndroidHardwareBufferRingDescriptor>

Implements

IEquatable<AndroidHardwareBufferRingDescriptor>

Remarks

Each buffer has the map's size in pixels, logical_size times the map's scale factor, and the format AHARDWAREBUFFER_FORMAT_R8G8B8A8_UNORM. Its usage is AHARDWAREBUFFER_USAGE_GPU_COLOR_OUTPUT, AHARDWAREBUFFER_USAGE_GPU_SAMPLED_IMAGE, and the bits of usage.

See mln_android_hardware_buffer_ring_descriptor in the C API reference.
