◆ readDM()

int readDM	(	Bimage *	p,
		int	readdata,
		int	img_select
	)

Reading a Digital Micrograph image file format.

Parameters

*p	the image structure.
readdata	flag to activate reading of image data.
img_select	image selection in multi-image file (-1 = all images).

Returns: int error code (<0 means failure). A 2D/3D image format used with CCD cameras in electron microscopy. File format extensions: .dm, .DM Two types: Fixed format (new) and the Macintosh format (old) Fixed format: Header size: 24 bytes (fixed). Byte order determination: An endian flag: Must be 65535 or swap everything Data types: many. Macintosh format: Hermitian Header size: 8 bytes (fixed). Byte order determination: Big-endian Data types: many.
