% PlugInName: baseinfo

% PlugInMenuPath: Math/Statistics/stepcounter

% PlugInDescription
This is a primitive plugin for the analysis of artificially
generated scans. It counts the number of steps in x-direction,
higher than 255 counts.

% PlugInUsage
Use with
active scan or a selected rectangle within the active scan.

% OptPlugInSources
You need one active scan.

% OptPlugInObjects
If a rectangle is selected the calculated information applies to the
content of the rectangle. Otherwise, the whole scan is analyzed.

% OptPlugInDest
The result is printed on the console, so you better have one open!

% OptPlugInConfig
None.

% OptPlugInKnownBugs
None

% OptPlugInNotes
Is there interest in a more general approach?
