		int32_t *	height
	)

Decode a TIFF held in memory into 8-bit RGBx, for the previews raw files embed.

Raws that do not embed a JPEG preview embed a TIFF one – every DNG written by Adobe's converter does, as do Phase One IIQ, Hasselblad 3FR and film scanners. This is the only decoder those previews need; libtiff reads a blob through TIFFClientOpen just as well as a file.

Parameters

blob	Encoded TIFF bytes. Not retained.
bufsize	Length of `blob`.
out	On success, receives a freshly allocated buffer of 4 bytes per pixel, laid out R, G, B, unused – the layout the JPEG preview path also produces. The caller owns it and must release it with dt_pixelpipe_cache_free_align(). Untouched on failure.
width	Receives the decoded width. Untouched on failure.
height	Receives the decoded height. Untouched on failure.

Returns: TRUE on success, FALSE if the blob is not a readable TIFF or allocation failed.
