Downloading Doffy

doffy.zip — the whole package, less than 500 kB

While I remain the copyright holder of the software, you are free to use it as you wish. If you publish the results in any way, give Doffy a credit — as a matter of good manners rather than a legal obligation.

Installation

None: just unzip the archive so that the doffy\ folder is easy to find. It should contain the following files:

• doffy.exe — the executable, i.e. program itself;
• doffy-whats-new.txt — a text file with update information;
• doffy.doff — a setup file with detailed description of all parameters;
• doffy-*.doff (where '*' means "anything") — a bunch of other .doff files, which you can discard, modify, whatever;
• doffy.css — Doffy does not use this file, but your browser does, when showing the generated file; therefore wherever you move the HTML output to another location, a copy of doffy.css has to follow.

If you wish, you may create a shortcut to Doffy on your desktop or Start Menu.

To uninstall, delete the Doffy folder.

Preparing the .doff file

This is a plain text file with a complete definition of the table to compute and its format. It is highly recommended that for each new table you create a new .doff file, so that at any moment you can come back to it, do any necessary changes, and generate the tweaked version.

The best way to start is to make a copy of doffy.doff under a new name, say, mzd-40-150-pro.doff, in the same folder where all Doffy files are. Then use a text editor (like Notepad, not a word processor!) to open and edit that new file. You will see something like this:

I don't think any more explanations are necessary. Just make sure you've got the CoC and Multiplier right (or set the latter to 0), and watch out when typing the lists of distance, aperture, and focal length values. You should be just fine.

Running Doffy

There are at least three ways to do it.

1. The Girlie Way

   Double-click at the Doffy Icon. The program will ask you, in a command-line window, for the .doff file name, so enter it, like mzd-40-150-pro.doff — done.

2. The Smartass Way

   Double-click on the .doff file icon. Windows will ask you to assign a program to handle .doff files. It is a painful process, but you do it only the first time. From now on you run Doffy by double-clicking on the .doff file. Look, Ma: no hands!

3. The Manly Way

   Open the command line window, navigate to the Doffy directory (that's the manly word for folder), enter program name followed by that of the .doff file, like

   doffy mzd-40-150-pro.doff

Doffy will run for a fraction of a second, and before terminating it will call your assigned Web browser showing the newly-created DoF table. The file name is the same as that of the setup file, except for the .html extension — mzd-40-150-pro.html in our example.
