% OPERASI_PIKSEL MATLAB code for operasi_piksel.fig
% OPERASI_PIKSEL, by itself, creates a new OPERASI_PIKSEL or raises the existing
% singleton*.
%
% H = OPERASI_PIKSEL returns the handle to a new OPERASI_PIKSEL or the handle to
% the existing singleton*.
%
% OPERASI_PIKSEL('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in OPERASI_PIKSEL.M with the given input arguments.
%
% OPERASI_PIKSEL('Property','Value',...) creates a new OPERASI_PIKSEL or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before operasi_piksel_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to operasi_piksel_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
