How to insert a raster image at 1/4"=1" scale

[Anonymous]

Any directions I find are so confusing. I have a .png of an elevation, set at 1/4"=1" and I'm trying to get dimensions off of it, but can't figure how to insert the image at the right scale. Any SIMPLE instructions anyone can give me would be much appreciated!!

Raster images are not scaled, so you cannot do what you want: if you need that, ask for a vector file (scaled PDF or DXF or DWG) of that image instead with scaling already set in it.
