Intaglio

Mac OSX uses PDF (Quartz) as standard vector graphics instead of legacy PICT (Quickdraw). Unfortunately, most of applications (including Keynote and MS PowerPoint) do not support any function to edit PDF directly. I used to save each file as PDF and edit it on Adobe Illustrator.
It is not a smart way, and so I tried Intaglio, a drawing application on Mac OSX.

The application requires only 15 MB of disk space but supports both Quartz and QuickDraw. It retains traditional drawing features of MacDraw and can convert old Claris/MacDraw drawings to Quartz graphics.




The exporting procedure of Intaglio is quite smart. Click and hold down the mouse button for a second: the cursor will change to a copy cursor and it allows you to drag graphics into other applications.


However, the exported objects are recognized as image on Keynote and PowerPoint. I send e-mail to Purgatory Design, the software company, inquiring about the limitation.

>> I guess Intaglio should have a saving option to export it as Keynote or Powerpoint file.

Answer: One option you can investigate now is to add the LinkBack plug-in to Keynote and enable LinkBack export in Intaglio's clipboard preferences. In this mode, Intaglio includes editable information with the PDF it exports to Keynote. If you want to edit the PDF later Intaglio will use that editable data instead of the PDF itself. For more information see:

LinkBack is an open source framework for Mac OS X exporting graphics to other applications with a link that enables the graphics to edit via the original one. It is in a similar way to Microsoft OLE or Apple's "publish and subscribe", and of course, these objects are unable to edit without the original applications.

OpenOffice and EasyDraw can export their drawings to PowerPoint or Keynote files. I wish Intaglio will have the function in the near future.
