img_stem_lut_apply()

int img_stem_lut_apply	(	Bimage *	p,
		int	neg_stain_flag
	)

readBrookhavenSTEM()

int readBrookhavenSTEM	(	Bimage *	p,
		int	readdata
	)

Reading a BrookhavenSTEM image file format.

Parameters

*p	the image structure.
readdata	flag to activate reading of image data.

Returns

int error code (<0 means failure). A 2D image format used for the Brookhaven STEM. It has a text header of 4096 bytes (fixed size). The default size is 512x512. File format extension: .dat. Data type: unsigned char. The header specifies the following keywords: SCAN: pixel size in internal units The data is packed into two interleaved channels which are unpacked into two separate images in this function. The first image contains the signal from the LA (large area) detector and the second image contains the signal from either the SA (small area) detector, or the BF (bright field) detector. The data is corrected for signal non-linearity on the fly when read in.
