SMART Notebook 10 for Windows Operating Systems
If you insert a graphics file on a page, you can create transparent areas within the graphic. This is useful for removing an image's background. You can make any color in a graphic transparent.
Press the object's menu arrow, and then select Set Picture Transparency.
The Picture Transparency dialog box appears.
Press any areas in the graphic that you want to make transparent.
NOTE: Pressing an area makes only that area transparent, even if the graphic includes that same color in other areas.
Press OK.
