Problem: I capture a screen from the PDF that consist of a program, using the Snapshot Tool option of the Acrobat Reader. The background of the screen is white and the foreground is black (the program text). Now, I want to copy the captured screen on a PowerPoint slide with a blue background. The problem is that the captured screen background (white) surpasses the blue background.

Is there any way so that I retain my PowerPoint background with only the foreground of the captured screen (the program text)?

Possible Solution: It is not a problem of PowerPoint. The image that you have captured has "white" color in the background. There is no "empty" or "hollow" through which you will see the background color of the slide.

There are two alternatives, use Paint or similar tool to change the background  white color to blue (if you have FullShot this is very easy). Or use a more powerful  tool like Photoshop that can create a "hollow" background for your image so that  you can see something though it.

[[BTW, I am just wondering how good will black text look on blue background.]]
