Public methods

nativeBindEGLImage

abstract boolean nativeBindEGLImage(int target, long eglImageHandle)

Binds an EGLImage to the specified texture target. Returns whether the binding is successful.

nativeCopyBitmapToHardwareBuffer

abstract boolean nativeCopyBitmapToHardwareBuffer(
    @NonNull Bitmap bitmap,
    @NonNull HardwareBuffer hb
)

Copies a Bitmap to a HardwareBuffer. Returns whether the copy is successful.

The destination HardwareBuffer must have HardwareBuffer.USAGE_CPU_WRITE_OFTEN usage.

The source Bitmap.Config must match the destination HardwareBuffer.getFormat, and be either Bitmap.Config.ARGB_8888 and HardwareBuffer.RGBA_8888 or Bitmap.Config.RGBA_1010102 and HardwareBuffer.RGBA_1010102.

nativeCopyHardwareBufferToHardwareBuffer

abstract boolean nativeCopyHardwareBufferToHardwareBuffer(
    @NonNull HardwareBuffer srcHb,
    @NonNull HardwareBuffer dstHb
)

Copies the contents of a source HardwareBuffer to a destination HardwareBuffer. Returns whether the copy is successful.

The source HardwareBuffer must have HardwareBuffer.USAGE_CPU_READ_OFTEN usage, and the destination HardwareBuffer must have HardwareBuffer.USAGE_CPU_WRITE_OFTEN usage.

The formats of the source and destination buffers must match, and be either HardwareBuffer.RGBA_8888 or HardwareBuffer.RGBA_1010102.

nativeCreateEglImageFromHardwareBuffer

abstract long nativeCreateEglImageFromHardwareBuffer(
    long displayHandle,
    @NonNull HardwareBuffer hardwareBuffer
)

Creates an EGLImage from a HardwareBuffer.

nativeDestroyEGLImage

abstract boolean nativeDestroyEGLImage(long displayHandle, long imageHandle)

Destroys an EGLImage. Returns whether the deletion is successful.
