Sorry it was in the June 13th post....
"most graphic editors should be able to select the white background and remove it".
It could have been more verbose.
Open the image in a graphic editor.
Crop to the area you want.
Most graphic editors have a magic wand that will select colour areas that have a sensitivity adjustment to differentiate between shades of blue. You were lucky that your image had high contrast between colours so selecting the regions was easy. Once selected the region was deleted.
Repeat for all the other shapes you want to extract.
So you end up with a collection of images with transparent backgrounds.
Open the file folder with these images and just drag and drop them on an open Visio drawing.
Then drags these images from the Visio drawing to the Visio document stencil and you will have Visio masters you can use in other Visio drawings. Next step is just renaming them to something more useful that masterxx..

I am looking forward to your other question.
