Mac Forum / Applications / PowerPoint / December 2004Best Vector Graphic Format for Mac/PC Compatiblitity
What is the best vector graphic format to use in powerpoint if I want to use both Office 2004 and Office XP to edit the files? We use 'Enhanced Metafile' on XP as this seems to work well, but many of these don't work so well in Mac - and embedded images (e.g. placing a PPT page into a PPT page) don't seem to work well either. PNG doesn't seem to be well copied from PC to Mac, and things like eps just look appalling. Hope someone can suggest something - it is tedious having to share documents across platforms with the current incompatiblities.

Once you have a graphic on a slide under either version of PPT, ungroup it until it won't ungroup any more, then regroup the selected shapes into a group. This converts everything to PPT (Office) native drawing objects; they'll cause the least x-platform problems. > PNG doesn't seem to be well copied from PC to Mac, and things like eps > just look appalling. PNG isn't a vector format in any case. EPS can be useful for printing to PS output devices and/or Acrobat Distiller, but otherwise it's not very useful in PowerPoint, especially on the PC ================================================ Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ > Once you have a graphic on a slide under either version of PPT, ungroup > it until it won't ungroup any more, then regroup the selected shapes > into a group. > > This converts everything to PPT (Office) native drawing objects; > they'll cause the least x-platform problems. Except that ungrouping objects causes wierdness sometimes when they are not created by MS applications in first place. >> PNG doesn't seem to be well copied from PC to Mac, and things like eps >> just look appalling. > > PNG isn't a vector format in any case.

Perhaps I'm missing something, or maybe ppt doesn't treat PNG properly? Gavin Lawrie Gavin, > Except that ungrouping objects causes wierdness sometimes when they are not created by MS applications in first place. True. I have seen this, particularly with gradients and odd-shaped fills > Well it can be - PNG is the native file format for FireWorks files - which includes vector and bit-map layers > seemingly without difficulty. Perhaps I'm missing something, or maybe ppt doesn't treat PNG properly? PNG is a bitmap format. http://www.libpng.org/pub/png/ TAJ > http://www.libpng.org/pub/png/ Interesting, PNG does appear to be a bitmap format. Wonder how Macromedia does it, as Fireworks files are stored in PNG format and yet include vector elements. All I want is to find a vector graphics format I can use to store vector graphic images in PPT presentations that will open and work well on both OS X and PC computers. Ungrouping imported objects (the only suggestion so far) is not the solution, as it doesn't work consistently or all the time. Nor it seems is PNG. Any other ideas how to do this? Regards Gavin Lawrie Forgetting PNG for a moment.... >We use 'Enhanced Metafile' on XP as this seems to work well, but many of these don't work so well in Mac What problems are you seeing on your macs with EMFs (enhanced windows metafiles)......

Exactly. And in years and years of running a slide service bureau that dealt with mostly PPT files, we learned that you could count on it: it it caused trouble in any other way, it'd go goofy when you ungrouped it. Turned around t'other way, ungrouping is your early warning system. If it snarls at you when you ungrouped it (at a time of YOUR convenience) it'd almost certainly have bitten you at the most inconvenient possible time later. > >> PNG doesn't seem to be well copied from PC to Mac, and things like eps > >> just look appalling.

PNG doesn't contain vector information. Bitmaps may be stored in PNG format internally within FireWorks files, but that doesn't mean the PNG format itself stores vectors. > Perhaps I'm missing something, or maybe ppt doesn't treat PNG properly? In what sense? The thread's about vector graphics. Where does PNG come into it? ================================================ Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ |
