Function Documentation

imb_is_a_tiff()

bool imb_is_a_tiff	(	const uchar *	mem,
		size_t	size )

Definition at line 18 of file format_tiff.cc.

References blender::imbuf::imb_oiio_check(), and size().

imb_load_tiff()

ImBuf * imb_load_tiff	(	const unsigned char *	mem,
		size_t	size,
		int	flags,
		ImFileColorSpace &	r_colorspace )

Loads a TIFF file.

Parameters

mem	Memory containing the TIFF file.
size	Size of the mem buffer.
flags	If flags has IB_test set then the file is not actually loaded, but all other operations take place.

Returns

A newly allocated ImBuf structure if successful, otherwise NULL.

imb_save_tiff()

bool imb_save_tiff	(	ImBuf *	ibuf,
		const char *	filepath,
		int	flags )

Saves a TIFF file.

ImBuf structures with 1, 3 or 4 bytes per pixel (GRAY, RGB, RGBA respectively) are accepted, and interpreted correctly. Note that the TIFF convention is to use pre-multiplied alpha, which can be achieved within Blender by setting premul alpha handling. Other alpha conventions are not strictly correct, but are permitted anyhow.

Parameters

ibuf	Image buffer.
filepath	Name of the TIFF file to create.
flags	Currently largely ignored.

Returns

1 if the function is successful, 0 on failure.
