Re: [OSSIM] 3x3ConvolutionFilter

[David B. <db...@co...>]

All,

The slot was hooked to a signal that did not exist.

Thanks for the code Matt, it's in cvs now.  I'm surprised that 
compiled.  Hidden by qmake stuff I guess.

I used the image chain editor, added the 3x3 and tested with no error.

Thanks for the bug report Fredric.

Dave

ps:  If you have the QT development package they have an application 
called "assistant".
Very good documentation on signal/slot scheme.
