function varargout = d_fetch(varargin)
% D_FETCH - fetch data points from graphics
% Usage:
% 1) Press 'Get image' to load graphics file (All matlab
% supported formats are ok, but occationally there seems
% to be some color problems with png -files)
% 2) Use 'Zoom on' to maximize the axis you're looking at,
% then lock the screen with 'Zoom off'
% 3) Mark the coordinates by entering coordinate values to edit boxes
% at 'Match X/Y', e.g., 0:2:10. Press 'Match X/Y' and point the
% specified coordinate values in the plot with mouse
% 4) 'Enter datapoints' - mouse left click enters a point
% - mouse right click exits the GINPUT loop
% 5) 'Save data' saves the data into a text file specified above the
% pushbutton
%
% NOTES! Program makes a linear fit to the given match points, if you're
% looking at log data, use the powers instead. Also, the image must be
% rotated so that the horizontal and vertical axes of the image are aligned
% with those of matlab axes - program doesn't take into account any rotations.
% D_FETCH writes the output file in the directory where the program is
% launched.
% D_FETCH M-file for d_fetch.fig
% D_FETCH, by itself, creates a new D_FETCH or raises the existing
% singleton*.
%
% H = D_FETCH returns the handle to a new D_FETCH or the handle to
% the existing singleton*.
%
% D_FETCH('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in D_FETCH.M with the given input arguments.
%
% D_FETCH('Property','Value',...) creates a new D_FETCH or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before d_fetch_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to d_fetch_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
