A family of Microsoft relational database management systems designed for ease of use.
I struggle with this problem too! Here's what I did - hope it helps someone else.
- I installed KB2883049
- added HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\15.0\Visio\Application DWORD Value: SupportHighResImage=1
- I had to add the Visio and Application keys - I didn't have Visio in 15.0
- I tried to install KB2881079 but got the error "There are no products affected by this package installed on this system"
But I still get very blury images when:
- using the Insert tab, 'Pictures' option
- dragging/dropping an image directly from File Explorer
BUT! I have found that if I first open the image in Photoshop, select all, copy, then PASTE the image into Visio I get full res! Woo!
A large high res image does seem to slow visio down very quickly, so something is still not right, but at least I can actually complete some work now!
