INTRO

Penpad is small widget for free-hand drawing.

This widget has been inspired by a lot of toy applications, many of those you can find at Tcl/tk wiki.

All those applications, re-implemented the same functionalities in a different way. It's time to standardize these common features, by providing a generic, reusable widget

Penpad is a pure-tcl widget, running on any platform. Tested on Windows and Unix (Linux).

With penpad you can:

• make your scribbles
• save your work in a file (gif, png, jpeg, ... ) or to the clipboard (Windows only)
• import a background image (with special "anchoring" properties ...)
• fully customize the widget's look
• apply all the canvas-widget options/commands (as a matter of fact, a penpad is a canvas )

For full details read the documentation :

• Penpad Reference
