90% of the time I use it, it is a control.

Click on this link http://forums.ni.com/t5/LabVIEW/Concatenate-Images/m-p/1152517#M506549 and then look at the bottom of Darin.K's post you will see and attachment called  CoryKArtworkGenerator.llb 685 KB. If you open that attachment you will a labview LLB Manger open with three vis in it. I believe the ScaleBitmap.vi will be useful for you. Let me know if you that works.

Wow. I can't believe LabView does not have a simple option for scaling bitmaps to the frame... Was it 25 years since first LabView release?... Sorry for the rant. I need to look closer to understand how ScaleBitmap works...

Probably because LabVIEW is a programming language, not an image viewing program.

I originally wrote scale bitmap many years and LV versions ago, I decided it was better than waiting for NI. 

It simply uses bilinear interpolation for each point in the bitmap.  When scaling up, for example, new points are added with fractional indices.  The values for these points are found by interpolating between the four nearest points in the original image. 

For extreme scaling, it will always be dodgy, but the best results are found by doing it in several smaller increments.
