Public attributes
Declared in android/hardware_buffer.h
uint32_t AHardwareBuffer_Desc::format
One of AHardwareBuffer_Format.
height
Declared in android/hardware_buffer.h
uint32_t AHardwareBuffer_Desc::height
layers
Declared in android/hardware_buffer.h
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
Declared in android/hardware_buffer.h
uint32_t AHardwareBuffer_Desc::rfu0
Initialize to zero, reserved for future use.
rfu1
Declared in android/hardware_buffer.h
uint64_t AHardwareBuffer_Desc::rfu1
Initialize to zero, reserved for future use.
stride
Declared in android/hardware_buffer.h
uint32_t AHardwareBuffer_Desc::stride
usage
Declared in android/hardware_buffer.h
uint64_t AHardwareBuffer_Desc::usage
Combination of AHardwareBuffer_UsageFlags.
width
Declared in android/hardware_buffer.h
uint32_t AHardwareBuffer_Desc::width
