Functions
int	readDI (Bimage *p, int readdata, int img_select)
	Reading a Digital Instruments image file format. A two-image 2D image format used in Digital Instruments atomic force microscopes. The header is text varying with the version of DI software, which may be 4,8,12,20K and is supposed to be read from the header itself. The header contains the following keywords (tags): image list: presumably one entry per image Data offset: offset to start of data, may however be incorrect if the file was transferred with ftp as text Data length: total length of data block Samps/line: samples per line (x-dimension) Number of lines: lines (y-dimension) list end: end of header File format extensions: .di, .DI Byte order: Always little endian because the DI software runs on Intel machines and there is no way to detect byte order from the text header. Data type: short. More...

Data type: short.

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).
