native fun nativeBindEGLImage(target: Int, eglImageHandle: Long): Boolean

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

native fun nativeCopyBitmapToHardwareBuffer(bitmap: Bitmap!, hb: HardwareBuffer!): Boolean

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

The destination HardwareBuffer must have USAGE_CPU_WRITE_OFTEN usage.

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

native fun nativeCopyHardwareBufferToHardwareBuffer(
    srcHb: HardwareBuffer!,
    dstHb: HardwareBuffer!
): Boolean

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

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

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

native fun nativeCreateEglImageFromHardwareBuffer(
