Powerpoint problem...images changed to negatives...HELP! - davester - 03-03-2010
My wife is preparing a Powerpoint presentation for a lecture tomorrow. She transferred the presentation from her PC at work to her mac at home and it looks fine, except that some of the images within the slides have become negatives. Does anybody know how to fix this?

I should point out that you can do this manually in Powerpoint and/or after she transfers it back to a Windows-based computer.

I've seen this as a JPEG glitch (where the JPEG version of an image displays w/inverted colors)... solution was to open the image in Preview and do a "Save As" to TIFF or another format and rebuild the slide.

She has powerpoint 2008. It has no add-in menu choice, presumably because m$ ditched VBA for no good reason. Therefore the add-in solution doesn't work. How do we get qat those jpeg images to fix them, jimbrady?

You don't have a Windows computer in the house?

No. We do have windows on her macbook pro, but don't have a windows version of powerpoint. She has powerpoint 2008. I do have powerpoint 2004 on my powerbook G4...would that help?

Yea...2004 should work or if she can remote in to an office computer and work it remotely.

Select the image, go to the Picture tab in the Formatting Palette, click the Effects icon, find "Color Invert" in the Color Effect section.

Thanks for that pointer Doc. Strangely, the color invert made the colors closer to what they were supposed to be, but all the line work came out in very light pastels, almost illegible. She ended up extracting those images, editing in GIMP, and putting them back in.
