The values of width, height, and viewBox can change from SVG to SVG based the tablet model and the screen resolution of the original screenshot jpeg/png. As long as the aspect ratio is maintained in the transition from jpeg/png file to the SVG as imported into OpenSCAD, it will work since I then resize it based on the known tablet screen dimensions. When OpenSCAD ignores edges of the SVG image because they don’t contain colored pixels, what is imported has a different aspect ratio from the original image.

Do you know the dimensions of the SVG file, or might (e.g.) different users end up using different scales?
