Trampoline! is a nearly pure-Tcl library extension that generates an Adobe Portable Document Format (PDF) document based upon the content of a Tk canvas. The intent of this extension is to provide a "modern" replacement for the Tk canvas widget command postscript, which generates a Postscript document based upon the content of a Tk canvas. Trampoline! is striving to be compliant with Adobe PDF Reference version 1.4.
Trampoline! supports all canvas item types, but not every item option, as yet. The Img extension is used to capture the Tk widgets displayed within canvas window items. This is why Trampoline! is described as being a "nearly pure-Tcl" extension. If the user does not plan on having canvas window items within the canvas, the Img extension does not need to be loaded. Trampoline! will still function properly as long as no window items are on the canvas.
