Copy-Paste vs. Insert-Image-From File

[Guest]

Here's the scenario:
I used Copy/Patse to bring a jpg image into a slide. I subsequenlty used the
"set transparent color" button on the Picture toolbar to make the image's
background transparent. The result gave me a very "fuzzy" background.
I then did a test by bringing the image in using: Insert/Picture/ From File.
I then performed the exact same technique to make this image's background
transparent. The result of this test gave me exactly what I was looking for:
No fuzzy" background. Is this an inherent limitation with copy/paste?

This is one of the many reasons to always use Insert/Picture/From File when
inserting a new picture. Copy/Paste is best for pictures that are already
in your presentation and you want them on a new slide.

Thank you for the response. But do you know the reason for the limitation of
Copy/Paste?

I don't know the details, but here are some links that begin to explain
it:

Copy & Pasting into a presentation creates an OLE object within PowerPoint
instead of a picture image. While they may look the same on the slide, they
are handled very differently.

An OLE object can not be compressed. An OLE object may depend on some
components being installed on the receiving computer. An OLE object may
bring other things into the presentation that are not wanted (hyperlinks,
etc.). An OLE object is larger than the picture it displays.

Insert Pict from file just brings the image, which PowerPoint can understand
and compress.

Bill, could you also explain how paste special works, please ?

 

[Steve Rindsberg]

When you copy something in Windows, the app you copy from may put several
different representations of the data on the clipboard.

When you simply Paste, you get whichever of those formats PPT chooses to
insert.

When you Paste Special, you get a chance to choose which of the available
formats to paste.
