in thread font measurement

I appears from this code (I am no perl professional) that a window is created for the text. In my case the measuring will only be used as a means to determine the length of the string to keep, and what to remove. So, it is just an intermediate step. So if this code opens a separate window I think that would have a significant performance hit on this already slow program (not the example I gave, but the real program I am working on).

    BrowserUk gave you the preferred answer below, but if you wanted to use my Canvas method, without invoking a window, all you need to do is comment out the line #MainLoop. Then if you run it, it will not show a window.

    Either way, you are loading Tk. You can either load Tk::Text or a Tk::Canvas. Tk is relatively light and fast to load.
