Public attributes

format

uint32_t AHardwareBuffer_Desc::format

One of AHardwareBuffer_Format.

height

uint32_t AHardwareBuffer_Desc::height

Height in pixels.

layers

uint32_t AHardwareBuffer_Desc::layers

Number of images in an image array.

AHardwareBuffers with one layer correspond to regular 2D textures. AHardwareBuffers with more than layer correspond to texture arrays. If the layer count is a multiple of 6 and the usage flag AHARDWAREBUFFER_USAGE_GPU_CUBE_MAP is present, the buffer is a cube map or a cube map array.

rfu0

uint32_t AHardwareBuffer_Desc::rfu0

Initialize to zero, reserved for future use.

rfu1

uint64_t AHardwareBuffer_Desc::rfu1

Initialize to zero, reserved for future use.

stride

uint32_t AHardwareBuffer_Desc::stride

Row stride in pixels, ignored for AHardwareBuffer_allocate()

usage

uint64_t AHardwareBuffer_Desc::usage

Combination of AHardwareBuffer_UsageFlags.

width

uint32_t AHardwareBuffer_Desc::width

Width in pixels.
