Cannot delete pages in Adobe Acrobat X on Windows 7

I have this trouble deleting pages using Adobe Acrobat X on Windows 7. It kept on issuing a warning “one or several pages are in use” and it says it cannot delete the page. The work around is to run Adobe Acrobat X in compatibility mode Windows XP SP3. To do this :

  1. Click Start menu, and type Adobe Acrobat
  2. Right click on the Adobe Acrobat from the start menu, and click Properties
  3. On the properties window, click Compatibility Tab
  4. And choose to run compatibility with Windows XP SP3.
  5. Click Ok, and re-run Adobe Acrobat X

This works for me.

Hi,

On my system, I get:

octave:10> whos
Variables in the current scope:

Attr Name            Size                     Bytes  Class
==== ====            ====                     =====  =====
ans             1×1                          1  uint8
f             256×256                    65536  uint8
g             256×256                    65536  uint8

in particular, f has integer values between 0 and 255 but you tell the
function that it has values between 0 and 1. The following should work:

g = imadjust(double(f)/255,[0,1],[1,0]);

Note that g is a double matrix then.

Regards,
Laurent
