MS Office Forum / General PowerPoint Questions / July 2006tiff corruption in conversion to powerpoint 2007
Most of the embedded tiffs in my medical imaging presenations were corrupted ? poor compression? when converted to 2007. If not corrected this could be very problematic for anyone who uses tiff for presentation. there are hundreds of images, most unique and irreplaceable, in each ppt file. any solutions? plans to fix? > Most of the embedded tiffs in my medical imaging presenations were corrupted > ? poor compression? when converted to 2007.

Don't use beta software? ;-) To fix the problem MS will need to narrow it down somewhat. Can you reproduce the problem by doing this: - Start with a new blank presentation in whatever version of PPT you use (include some text to indicate this on the slide) - Add a blank slide and use Insert, Picture, From File to bring in one or two of your example TIFFs. (Or use whatever method you currently use, but note it on the slide also. Note also the source of the TIFFs - application and version that created them.) - Save - Open in PPT2007 and see corrupted images (make a screenshot of same and save it in an independent PNG file) If so, I'll be happy to forward the info to MS so they can attempt to solve the problem. email to steve at-sign pptools dot com ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ Honestly more concerned this factor will be incorporated into product thanover the corruption of one file. I was able to retrieve an old version. I will do as you suggest in a day or two. The images had lost dynamic range as if poorly compressed. I could send you images pre and post faster. > > Most of the embedded tiffs in my medical imaging presenations were corrupted > > ? poor compression? when converted to 2007.

That's what I understood you to mean, and appreciate it. I was able to retrieve an old version. > I will do as you suggest in a day or two.

Ideally starting with a blank presentation as I mentioned, because if you begin with an existing presentation, there's no way of telling what kind of history is built into it ... what other versions it's been through. > > > Most of the embedded tiffs in my medical imaging presenations were corrupted > > > ? poor compression? when converted to 2007.

To drive Steve's point home: I submitted a presentation that had mangled up pictures to MS as PPT 2007 bug a while ago. MS figured out that the reason for this was a bug in PPT 2003...Had the presentation been created with a blank slate in PPT 2007, it would have been evident that it wasn't a 2007 issue.

Thanks for that ... makes things much clearer! Appreciate your efforts. Nearly all my presentations have beeen through multiple generations of ppt. Is there a way to 'clean' them in 2003 before trying 2007 again. (FYI) Will work your trial this weekend. article <#Xpit$fsGHA.3892@TK2MSFTNGP02.phx.gbl>, Patrick Schmid wrote: > > > Better's better than faster <g>. > > > In order to solve the problem, they'll have to replicate it.

Followup: I've gotten the sample images and was able to recreate the same problem from scratch here. Interestingly, it requires both a JPG and a TIF on the same slide, it seems. Just the TIF by itself didn't provoke the problem. > Appreciate your efforts. Nearly all my presentations have beeen through > multiple generations of ppt.

One from a dig camera and one from efilm dicom viewer ver 1.5.3 which was a dicom image exported as tiff. Saved the ppt and exported the frame as png Emailed to another pc that had the beta installed over 2003. Opened the file (images looked fine) hit save (by accident..dont know the new ribbon) and the tiff image (only) appeared corrupted (note the reduced grey scale and ‘sheen’) Exported the 2007 frame as png. Note that the corruption incident initially was on my laptop and this event was on a new desktop. I am pleased to see the issue is reproducible > > Better's better than faster <g>. > > In order to solve the problem, they'll have to replicate it.
