Decode() [2/2]

std::unique_ptr< SkCodec > SkHeifDecoder::Decode	(	std::unique_ptr< SkStream >	stream,
		SkCodec::Result *	outResult,
		SkCodecs::DecodeContext	ctx = nullptr
	)

Attempts to decode the given bytes as a HEIF (or AVIF).

If the bytes are not a HEIF (or AVIF), returns nullptr.

DecodeContext is treated as a SkCodec::SelectionPolicy*

IsHeif()

bool SkHeifDecoder::IsHeif	(	const void *	data,
		size_t	len
	)

Returns true if this data claims to be a HEIF (or AVIF) image.
