8.7 Filming from the canvas

Some Ipe users make presentation videos directly from Ipe, as follows:

• Make Ipe full-screen (Zoom menu);
• Turn off the grid (Zoom menu);
• Enable pretty display (Zoom menu);
• Mac: Turn off the Snap toolbar and possibly the mode toolbar (Zoom menu);
• Linux: Turn off or rearrange toolbars and panels to taste;
• Windows: Turn off or rearrange toolbars by setting prefs.win_toolbar_order;
• Set up your video software to film the canvas area of Ipe (where your document is shown).

You can now go through your presentation, using the Laser pointer mode to point to items on your slide, and using ink mode to write annotations directly onto the slides.

For this to work well, it is essential that the width of the canvas remains fixed while you step through your document. Try it before you start filming! You can change the contents of the "View" and "Page" buttons by changing the preferences prefs.view_button_prefix and prefs.page_button_prefix. Furthermore, on MacOS, you can force the canvas width to remain fixed by making prefs.osx_properties_width large enough.
