Mac Forum / Applications / PowerPoint / April 2005Equation graphics in PowerPoint 2004
I have a lot of presentations that I put together 5-10 years ago using various PC versions of PowerPoint. I am now using Macs exclusively, and have run into difficulty when I open these old presentations with Mac PowerPoint 2004. Specifically, all of the equations show as random collections of black squares. When I double-click them, the equation editor opens normally, and the original information looks fine; it's just the rendering that seems to be a problem. There seems to be no capability to recolor these objects from PowerPoint itself. Is there some sort of converter or reformatter that can be used to clean these equations up? I don't have the time or patience to go through hundreds of these things and re-enter them all... Thanks JEH > I have a lot of presentations that I put together 5-10 years > ago using various PC versions of PowerPoint...and have > run into difficulty when I open these old presentations with > PowerPoint 2004...Is there some sort of converter or > reformatter that can be used to clean these equations up? I'm not aware of one, but you'd no doubt have better success with MathType. You could try the free evaluation and see if it works (link in my sig). MathType should be able to convert any equation that was created on either the Mac or the PC -- even from the old versions of Equation Editor.

MathType certainly has more features than Equation Editor. It allowed me to change the font color on an existing equation, and this allowed me to see what is going on. Each individual character or symbol in the equation seems to have a black background, so when the character itself was black, all I saw was black rectangles. Now I can see yellow symbols on black rectangles, which is an improvement, but not quite there yet. When I create a new equation, the font does not behave this way: no black rectangles. Therefore, I must conclude that the problem comes about in converting the PC files to the Mac. Bummer... What might cause the fonts to behave this way? Do you, or anyone, know what one might do to fix this problem?

Bummer... That's a logical conclusion based on the evidence, but I don't know why this would happen > What might cause the fonts to behave this way?

You might try our support staff at support@dessci.com, and send them a sample presentation with a couple of slides in it. You should be able to take one of the bad ones and delete all but a couple of slides, then save it with a different name before you send it.

With these, I can apply recoloring either in the server app or in the Format Object context menu, but the fonts still have this black rectangle background. Sounds like this might be a Microsoft problem with conversion of OLE objects from PC to Mac. Oh well, at least I found out about MathType. Now all I have to do is find the hundred bucks...

On the PC, EquationEditor relies on a special font being installed. I don't EqEd installed so I don't know offhand what font it is. But what you're describing sounds like what might happen if the needed font isn't available. ================================================ Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ > On the PC, EquationEditor relies on a special font being > installed.

The font is MTExtra, but I don't think the lack of this font would cause the background to turn black.

In light of what you wrote later, I agree. Hadn't seen that when I replied earlier. I've seen the effect you're describing in other situations; never found a good way of dealing with it other than bruteforce reformatting. However, if it's a matter of doing the same thing to each selected shape, a lot of tedium could be replaced with a little VBA code. If you can describe what you have to do to fix things up, maybe we can cobble something up. ================================================ Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ |
