I'm curious what program you're using to generate the images...
It’s a combination of a few tools, mostly built in to MacOS, depending on the type of graphic. Usually:
Base layer is SketchUp, with still images stitched to create a higher-resolution panoramic image with less discernible noise. Then imported to Photos where effects are added > exported to Preview to isolate the image using the instant-alpha tool > imported to a page-layout document in Pages where the background, text and graphics are added > exported as a high-res PDF > exported to JPEG again in Preview.
