Text is rough after saving slides to BMP or Tiff

Why is it that the text is very Jagged after saving to one of the high qulity
formats in PPT 2003 ( BMP - Tiff )? They look great on screen when editing
but I need to save the slides as pictures and they have to be high quality.
wmf and emf are not options - too large. I'm using standard fonts ( arial and
arial bold). Is there a way to bump up the quality so that the text remains
smooth?
Thanks,
Shawn
 
I dunno, I usually find that WMF is smaller than, say, PNG. But PNG is my
choice of export, especially if I'm working with text, as WMFs can simply be
ungrouped.

Anyway, try

Improve PowerPoint's GIF, BMP, PNG, JPG export resolution

And see if PNG doesn't do better.
 
Thanks Echo s, sorry for the double post!

Unfortunately, text-to-bitmap export in PowerPoint 2003 seems badly broken.

If you only need a screen-rez image, do screenshots of your presentation in
slideshow mode.

You could also try printing to PDF (if you have Acrobat) and exporting from
Acrobat to bitmap format.

Or export to higher rez images then downsample to get better quality lower rez
results.
 
One of our users here was having this problem also. Seems that indeed the ppt
rasterizing method for test looks bad when you view an exported image. One
way to get better image quality is to bump up the output resolution of the
exported images and then resize them down in Photoshop (or whatever editor
you use). In our case we set the output resolution for ppt exports to 300 ppi
(you can read how to do this here
http://support.microsoft.com/default.aspx?scid=kb;en-us;827745&Product=ppt2003 )
Once you have the out put image (text still looks a bit jagged) then we have
photoshop run a batch of resizes to our target size. The resulting images
look like they did when we were using PPT XPand 2000.
 
Ahhh, here is another issue. It seems that what is happening is that your
text in PowerPoint is that the actual text really does look this way in the
powerpoint slide. The problem is that font smoothing is enabled on your
system and it affects the text displayed in your slide. If you turn off font
smoothing in the display properties (go to the appearance tab and click on
the "effects" button) you will see your text in the slide will look jagged
just like in your bitmap. Tiff, png, etc. This is why your output image looks
like it does because the image is a true representation of what you have in
your slide. Once the text is output as part of the image file Windows no
longer recognizes it as a piece of text because it is now one bitmap image.
The font smoothing is not being applied to it so the text looks jagged. Using
the "outputting to 300ppi " steps I mentioned in my previous post will result
in a good looking final image as the image resampling process down from the
300 ppi image has an anti-aliasing effect on the text in the image.
 
Font smoothing can affect what you see on screen from w/in PPT, no question.

But there's also no question that 2003 exports text only after running it through the
doggie-toy filter. First let the dog chew on it, then send it along. ;-)

Horrid stuff.

Well. *ALMOST* as good. ;-)

Believe me, I've done lots of side-by-sides on this one. Antialiased text like you
get from 2000 is always going to beat an antialiased bitmap of text.

It's worth keeping an old copy of PPT2000 around if you need to do lots of bitmap
exports.
 
I know this is an old post, but for those still having this problem (like me)
I fixed it. I switched to Microsoft Office X for Mac :-) It saves
PowerPoint slides as images and the text looks beautiful! You can also change
the resolution in the Save As options without having to edit the registry
manually.
 
Ah, that's great news. I had no idea Mac PPT would do this. Thanks for
posting it.

In my experience, PNG is the best raster format for PPT text on the PC.
WMF/EMF (vector) is really the best for text, but it can also be ungrouped,
and sometimes that's not what I need.
