Function Documentation

tex_orientations_match()

bool tex_orientations_match	(	size_t	src_flags,
		size_t	dst_orientation
	)

indicate if the two vertical orientations match.

used by tex_codec.

Parameters

src_flags	TexFlags, used to extract the orientation. we ask for this instead of src_orientation so callers don't have to mask off TEX_ORIENTATION.
dst_orientation	orientation to compare against. can be one of TEX_BOTTOM_UP, TEX_TOP_DOWN, or 0 for the "global orientation".

Returns

bool

tex_validate_plain_format()

basically, this is the "plain" format understood by all codecs and tex_codec_plain_transform.

Parameters

bpp	bits per pixel
flags	TexFlags
