bug in blkrep?Started by:Arp, 03/04/2010 10:20AM
Hi!

Is there a bug in blkrep?

Because, I have a fits file with the
dimension 512x1, its one line.
If I want to enlarge it to 512x512 I
would use blkrep and use 512 for
dimension 2. but this simply does
nothing... the resulting image has the
same dimen...

Hi Mike,
