Artifacts Appear On PNG Import After Rotation

[Anonymous]

Revit 2020

We are trying to see what old projects look like on a current lot for a client. I save the PDF Floorplan as a JPG then in Photoshop cut and crop the image so I can import a PNG to overlay on the lot image. After importing the PNG if we rotate it artifacts appear on the image. 

Other formats come with their own issues. TIFF provides transparency but it only imports a skewed portion of the image. 

I need the image to be transparent so I can properly overlay on scale.

You said you have the floor plan in PDF... do you have it in CAD?  If no, can you convert your PDF to a .dwg file?  May have an easier time working.

If you're using Revit 2020 you can insert the PDF directly into Revit.

The architects in my office have CAD so I'd have to have one of them convert it, but would it even provide the background transparency I need?

This would be an option if it imported the PDF with transparency. That's part of the goal is to import a floorplan with the white background surrounding it removed so we can overlay the plans onto an image of the lot it would be used for. 
I am able to successfully save a pdf with the transparency but when I import that file into revit the background comes back. I have also used a TIF and a BMP but they came with their own issues. 

At this point we've just settled on having my boss use photoshop with the different plans on each layer so he can show the clients their options, but it would be nice to know why the issue with the PNG is occurring so we can resolve it for future reference.

The CAD import may have a layer for transparency, depending on how the PDF was set up.

I'm sure that you have your processes - but it seems to me that the easiest method would be to draw a floor and walls in Revit or use area plans for high level.  It appears that you're going through a lot of effort to show some options. 

If you're using Photoshop it may be easier to just overlay the drawings in PS using an image from Google Earth and leave Revit out of it for now.
