 SuPDF is a small utility that creates a one page PDF document
for a Sudoku puzzle. The values for the Sudoku puzzle are entered
as a text string, and SuPDF will format the result, adding pencil
marks or printing the solution, depending on the user's
preference.
SuPDF doesn't actually generate puzzles, but it will check
them for correctness, i.e., make sure there is a single unique
solution. It also can create a variety of output grids, and each
PDF file can contain one or two of the following:

Mini-FAQ
|
Q:
|
How do I print out the PDF files once I create them?
|

A:

Adobe's Reader™ software will open and print the
PDF files; it is a free download from the Adobe
web site.

Q:
|
I tried to paste a multi-line Sudoku puzzle, but only the last
line appeared. What happened?
|
|
A:
|
Use the “Paste Text” button on the toolbar to
paste a multi-line or formatted Sudoku puzzle from the
clipboard. This will ‘clean up’ the text and
remove any unnecessary characters.

Q:

Can you add a (insert wish here) feature to SuPDF?

about it.

Q:
|
I found a bug…can you fix it?
|
|
A:
|
Yes, but only if you can describe the problem well enough
for me to reproduce it. At the very least, I'll need to
know the puzzle, and while you don't need to go into
great detail about your computer, knowing which version of
Windows you're using would help.
