NAME

       g3data	  --  A tool for extracting data from graphs.

SYNOPSIS

       g3data [-max x y]  [-scale factor]  [-coords llx lly rux ruy]  [-errors]  [-lnx]  [-lny]  [filename(s) ...]

DESCRIPTION

       2001-01-01;

       g3data  is  a  tool  for  extracting  data  from scanned graphs. For graphs published in scientific articles the actual data is usually not

		 effect.

       -scale factor
		 Scales the picture size by factor. This parameter nullifies effect of the -max parameter.

       -coords llx lly rux ruy
		 Preset the coordinates of the left lower (ll) corner and the right upper (ru) corner.

       -errors	 Print out the error of the x value in column 3 and the error of y value in column 4 of the output.

       -lnx	 Use logarithmic scale for x coordinates.

       -lny	 Use logarithmic scale for y coordinates.

       filename(s) ...
		 The filename(s) of the image(s) to open.  Supported image formats: PNG, XPM, JPEG, TIFF, PNM, RAS, BMP and GIF.

USAGE

       g3data -scale 2 -errors test1.png

       g3data -scale 2 -lny -errors test2.png
