Mac Cody's nearly pure-Tcl PDF-savvy extension, whose home is on SourceForge at http://trampoline.sourceforge.net
AET 11may05 Trampoline is en extension to enable Adobe PDF output from the canvas. From SourceForge:-
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.
DPE 10 May 2005 Thanks for a useful package. I found a bug with text that contains nothing but whitespace which causes generate to fail. This can be fixed by adding the following lines near the top of TextConvert:
# Do not process blank text
if {[string trim [$w itemcget $item -text]] == ""} {
return ""
}RS: Trampoline is also a coding concept to allow unbounded recursion.
