%kvlastero 'Last Erosion'
% This MatLab function was automatically generated by a converter (KhorosToMatLab) from the Khoros vlastero.pane file
%
% Parameters: 
% InputFile: i 'Input Image', required: 'input image'
% InputFile: str 'Struct Element', required: 'Structuring Element'
% OutputFile: o 'Output Image ', required: 'resulting output image'
%
% Example: o = kvlastero({i, str}, {'i','';'str','';'o',''})
%
% Khoros helpfile follows below:
%
%  PROGRAM
% vlastero - Last Erosion
%
%  DESCRIPTION
% .I vlastero
% will do the last erosion of an input image by a set structuring element.
% 
% The output image data type will be the same as that of the highest data type 
% of the input image.
%
%  
%
%  EXAMPLES
% vlastero -i ball.xv -str b272.str -o outimage.xv
% 
% Will do the last erosion of image "ball.xv" by the structuring set b272.str, with the resulting image written to "outimage.xv".
%
%  "SEE ALSO"
% vcast1(1)
%
%  RESTRICTIONS 
% .I vlastero
% can be defined for all data types supported by Khoros, but at the moment it has been implemented just for the bit and unsigned char types.
% The structuring elements are subsets of the 3x3 matrix and the origin is always at the center of this matrix.
