All you Java Experts,

I'd like to open images in imageJ and have it automatically read in image
dimensions in units such as mm or cm for performing area and length
measurements using the ROI tools.  This feature seems to work well for DICOM
formats.  However it hasn't worked for me when I've tried adjusting the
header to png files.  Is there an image file format, preferably simpler than
DICOM files, that this works well for?  Additionally, what I'd like to do is
write an image file from a numpy array in python, then open the image in
imageJ and see information about the physical size of the thing the image
represents be read from the header.  If anyone has done this or something
similar advice would be greatly appreciated.  Also, I don't know where to
begin with Java programming.  Though, I am comfortable working with C/C++

Thanks,

Nick
