rtree-eps — create a PostScript plot from R-tree JSON


rtree-eps [-h ] [-m margin] [-o file] [-s style] [-v ] [-V ] [-W width] [file]


The rtree-eps program reads two-dimensional R-tree files in the rtree-json(5) format, as produced by rtree-build(1) , and writes encapsulated PostScript to the file specified by the --output option (or standard output).


-h, --help

List the program options.

-m, --margin margin

Add a margin (in units of PostScript points) around the plot, this is useful if converting the plot to a raster format, to avoid edge effects caused by anti-aliasing. If not specified then a value of 0.0 is taken.

-o, --output file

Write the output to file, rather than stdout.

-s, --style style

Style the plot as specified by style. The format of these files is described in rtree-style(5) and a number of such are included with the program.

-v, --verbose

Verbose operation.

-V, --version

Version information.

-W, --width width

Create a plot with the specified width (in units of PostScript points, 1/72 inch) rather than the default of 216 (three inches). The data in the input will be scaled to fit this width, which determines the plot height.
