% PlugInDocuCaption: Horizontal merge
% PlugInName: merge_h
% PlugInAuthor: Percy Zahl
% PlugInAuthorEmail: zahl@users.sf.net
% PlugInMenuPath: Math/Transformations/Merge H

% PlugInDescription
Used to horizontal merge to scans together. The scan are expected to
have same height.

% PlugInUsage
Call \GxsmMenu{Math/Transformations/Merge H}.

% OptPlugInSources
The active and X channel are merged.

%% OptPlugInObjects
%A optional rectangle is used for data extraction...

% OptPlugInDest
The computation result is placed into an existing math channel, else
into a new created math channel.

%% OptPlugInConfig
%describe the configuration options of your plug in here!

%% OptPlugInNotes
%The scan are expected to have same height.
