I preciously submitted an article “High quality diagonal lines” and receive several responses. Thanks to all. However I am still puzzled on how to proceed using TurboCAD 19 Pro Platinum and to do this as easy as possible. Obviously TurboCAD diagonal lines are mathematically straight, but are displayed as jagged for simplicity. Can I change this representation right in TurboCAD? If not Jeff suggests saving an image as a .png and then using Setup to specify the pixel count of 3000x2400 and 7 megapixels. I do this but now what? I open this .jpg file and get a picture but still with the jagged lines.
