Overview
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 explicitly given ; g3data makes the process of extracting this data easy.
Options
- -max x y
-
If picture is larger x-wise than x or y-wise than y, the picture is scaled down accordingly otherwise this parameter has no 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.
