When you try to print your presentation, some images may not
print as they appear in the presentation. Shadows may be lost, transparencies
may not print or the printed output may be very grainy, and some rotated
graphics may not be rotated.
This issue occurs if you have used the Paste
command in PowerPoint to paste the image as a picture. This
converts the image to a Windows Metafile Format (WMF) vector image. If the
original image was a bitmap, such as a Joint Photographic Exchange Graphic
(JPEG or .jpg) file or a Portable Network Graphic (PNG) file, the bitmap is
"encapsulated" in the WMF format. This may cause the advanced graphics features
of PowerPoint to not print as you expect.
To work around this issue if you want to convert images and
clipart to a different image format, use the Paste Special
command to paste as a picture (PNG). The PNG format uses a "lossless"
compression algorithm, so that information is not lost if you convert the image
to this image format.
