How to delete a white square background of a logo so it is round?

[Guest]

I want to paste a logo in my presentation. When i downloaded it, it has the
usual square white background which i want to delete as my presentation has a
blue background. I know that in Corel for example you can delete it by using
a mask... how can i do it in power point?

It depends on how your original logo file was created:

1. If it was an illustration, you can probably ungroup the logo, and delete
the white backdrop object.

2. If it is an illustration that won't ungroup -- and you have the original
file, open it in a drawing program and delete the white box. If you can't do
that, you could probably ask the person who gave you the logo if they have a
version with the white box removed.

3. If it is a bitmap picture, you can try using PowerPoint's Make Color
Transparent option to make the white color box not visible.

4. If you are familiar with a photo editing application like Photoshop (or
any other), you can remove the white box, and save it as a transparent PNG
or TIFF that you can bring into PowerPoint.

Depending upon the approach you take, you might have more questions -- do
get back and let us know.

Sil,
You could try and use the transparency tool from the picture toolbar. Click
on the white rectangle, so the blue background will appear.
There is an excellent tutorial here on applying transparency, that might
help:
