Pinebush Technologies [L1 ] makes HyperPlot and HyperXpress raster image processing software. In short, we sell software to print really big files in various formats to virtually any printer or plotter really fast. ENCAD [L2 ] and others OEM our product to drive their plotters.
We use Tcl and TclX as a cross-platform scripting framework and Tcl/Tk with BWidgets to build our user interfaces.
