data = read_adsc(filename)
Read an image file written by an ADSC detector.
ADSC detectors write images in the "SMV" file format which consists of a text header and uncompressed image.
ADSC_read takes the file 'fname' and returns the image information in 'imag' and text header in 'header'.
A typical header begins,
{
HEADER_BYTES= 512;
DIM=2;
BYTE_ORDER=little_endian;
TYPE=unsigned_short;
SIZE1=1152;
SIZE2=1152;
PIXEL_SIZE=0.0816; ...
From this one can rapidly determine,
a) The header is a 512 bytes long.
b) 512 bytes into the file, the image is stored as a set of SIZE1*SIZE2 unsigned_short integers.
ADSC_read determines the size of the header,
places the header info in 'header',
determines the image size,
places the image in imag.
At present ADSC_read has very little consistency checking.
Furthermore, at present we assume the image consists of unsigned 16-bit integers.
However, it should at least return the first Nmin=512 bytes of the file in header.
