What is Penny Paint?

Penny is a Spline based drawing and painting engine, developed by Dan Ritchie, and which was first introduced with Project Dogwaffle version 2.1

Penny Paint is an alternate paint engine expanding Project Dogwaffle's capabilities with Spline smoothing of mouse strokes. It is included for free with most versions of Project Dogwaffle, including PD Artist and PD Howler, and also as a free add-on by download for PD Particles. If you still use the older versions such as PD Pro 3, 4, 5 or similar, there is Penny Paint for that too.

Great for cartoonists who have a fast hand with the mouse or their graphic tablet and who  still want their line art to remain perfectly smooth, i.e. without jagged corners, this paint engine uses Spline interpolation between the sampled mouse/tablet points, so it looks perfectly smooth without line segmentation no matter how fast you draw your lines. It's perfect for artists with a fast hand, or those used to perfectly smooth lines seen in some vector drawing products. Here you can get the same results - with raster based drawing tools. It looks like vector lines, without the hassles of,...well, vector lines.

Note that if you want true vector objects, at least temporarily, you can use the Linear tool in Howler. There you deal with control points through which you define the smooth Spline or Bezier curve. Not here in Penny. With Penny, you immediately draw into the raster image. But it looks perfectly smooth, antialiased and scrisp as could be. Plus, there are some very cool extra options such as transparency, feathering or paper texture controls.

Penny paint - and you thought you'd just get one paint program with Dogwaffle..... You actually got two!

What's New?

Not much news with Penny. It's here, enjoy.

Sept. 2008 - version 1.1:
  • fixes a bug when the Penny paint window was maximized, it would crash when trying to fit the image to the window
  • corrected the tooltips for the middle row of icons (viewing tools).They had tooltips inherited from the row of tools below.
  • added the version number in the window title
  • added 'Penny' to the tools window title (now: Penny Tools) to help differentiate it from the main PD floating tools window
  • when changing the 'Mode', you will now see the selected mode in the label of the menu button. Also, if changing between brushes, it can cause the mode to be reset and this too will now show in the Mode label
  • Undo levels increased from 32 to 256 in Penny for PD Particles and PD Artist. Increased to 1024 levels in Penny for PD Pro. When using Penny 1.1 on the free version 1.2 of Dogwaffle or 2.x, it offers 64 levels of undo.


Penny is essentially a "paint program within the paint program". In otherwords: it's not a standalone drawing gadget: in order to use it, PD Particles must be already running. If in fact you start Penny first, i.e. before PD Particles, then this will cause PD Particles to be launched too: Penny looks for and attempts to establish a connection to the PD Particles.

When you launch Penny, the first thing it will do is to display a small, new tools panel. The existing main tools panel won't disappear, but while Penny is running, you will want to focus on the new tools offered in the Penny Tools panel.

There are only a few brushes in this Tools panel, plus some familiar viewing controls, and tools to send images to and from the Penny drawing area. There's also the Undo tooland you can use the keyboard shortcut 'u' for undo.

The next thing that happens is that a new image buffer is created, and a copy of the current image from PD Particles main image buffer is placed in it. In other words: Penny doesn't start with an empty image: it starts with whatever is in PD Particles at that moment when you launch Penny.

Penny then lets you draw in this temporary image buffer. You can start by clearing its buffer, or continue from that image and add to it.

One of the first things you might want to do is to change the brush size from the Size slider, because it might be too thin for you at first.

When you're done drawing with Penny, simply close the temporary image buffer from Penny. This will cause the Penny image buffer content to be pasted back into the main image buffer. In other words: it will automatically save the last image you had just prior to closing the Penny drawing area. 

Or, you could use one of the tools on the Penny tools panel to send the image back to the main image buffer. Penny will continue running. If you use the cooltools plugins, you could then 'store' the regular image buffer at this stage, to grab and store a snapshot in memory for later uses.
So why might you want to use Penny? What's so special about the tools found in Penny?

There are only four brushes, but they are of particular interest to cartoonists, Anime and Manga artists, and artists who like to draw lineart.

  • Penny brushes are Spline interpolated: no matter how fast your hand is, you will never see line segments even if you make very short turns. The curves are always... well, curvy.

  • Penny brushes are anti-aliased: you will not see any jaggies, guaranteed.
  • Penny brushes are Pressure sensitive. They're perfect for use with tablets.

There is also some control of Opacity, paper texture intensity, size and a few other parameters.

These are the 4 types of brushes found in Penny:
  • Pen

Drawing with the Pen
  • Water Brush

Drawing with  the Water Brush
  • Ink

Drawing with Ink, changingvalues of Press, opacity or paper

  • Gel brush

That's it, in a nutshell. The only ingredient missing is what you'll bring to it: your talent to draw line art for Anime, cartoons and comics. Have fun with Penny!
