Description

image files created by some versions of AIPS++ since release 1.3 cannot be be read by versions 1.3 and earlier. The period for which development versions of AIPS++ were creating image files which were unreadable by earlier versions was a 2-3 weeks so it is very unlikely you will ecnounter this problem.

This function converts the image disk file (actually just the Storage Manager of the logtable) so that it can be read by all versions.

If the outfile is unset, the conversion is done in-situ. Otherwise you should specify the name of a new disk file.

Example

 
- im := image('in.im');
- im.convertsm()                       # in-situ
- im.convertsm('out.im', overwrite=T)  # new output file
