Member Function Documentation

static uchar_t* RAWIO::raw_in	(	char *	filename,
		uchar_t *	type,
		int *	w,
		int *	h,
		uchar_t **	data_sub,
		char *	init_threshold
	)			[inline, static]

Read raw file.

Parameters:

	filename	The file to read.
	type	The fileformat-type.
	w	The width of the stored image.
	h	The height of the stored image.
	data_sub	[deprecated] - just pass NULL.
	init_threshold	Initial threshold (important for EZW compressed files).

Returns:

Returns a pointer to the read data on success and NULL if an error occurs.

Returns:

Returns a pointer to the read data on success and NULL if an error occurs.

static int RAWIO::raw_in	(	char *	filename,
		imgdata_t *	dst_for_reading_in
	)			[inline, static]

Read raw file.

Parameters:

	filename	The file to read.
	dst_for_reading_in	The destination for the data that is read in.

Returns:

Returns 0 on success and -1 if an error occurs.

	)			[inline, static]

Write raw file.

Parameters:

	h	The height of the data to write.
	to_output	Dominant pass data for output (EZW).
	to_output_sub	Subordinate pass data for output (EZW).
	init_threshold	Initial threshold (important for EZW compressed files).

Returns:

Returns 1 on success and -1 if an error occurs.
