With the program there are two testdata files included, test1.gif and
5
test2.gif. Their corresponding data can be found in test1.values and
8
To test the program start it with the command 'g3data test1.gif' or with
9
'g3data test2.gif'. When the program has started click on the button

labelled 'Set point 1 on X axis' and set out the corresponding point on
11
the image by pressing on it. Do the same for point 2 on the X axis, point
12
1 on the Y axis and point 2 on the Y axis. The axispoints can also be put
13
out by pressing the middle mousebutton for xaxis and the right button for
14
y axis. Fill out the entry boxes for the values of the axis points.
15
Then continue by putting out the points on the graph itself.

If you by accident put out an point where it doesn't belong you can
18
remove it by pressing the 'Remove last point' button. To remove all
19
put out points press the 'Remove all points' button. The axis points
20
can be reset by pressing the corresponding button.

After all the points been put out, press the 'Print data' button and
23
the coordinates of the data will be printed out through stdout.

If you'd like to write the data to a file, fill out the filename entry
25
box and press the 'Print to file' button.
