Do you really need to same memory by reducing the source size? I think you should left the source size alone and sample the image from the full source. Source size for SVG doesn’t make any sense, it’s vectoriel, doesn’t have any size, it can scale to any dimension.
This isn't accurate. SVG files have a builtin "wanted" size, which is IIRC what Qt would use by default:
https://www.w3.org/TR/SVG11/struct.html#SVGElementWidthAttribute
By explictly setting `sourceSize` you're asking Qt to rasterize the SVG at a different resolution rather than the wanted one (and downscaling when rendering).
