Would it be possible to create a component that is larger than screen size(2000 x 1500 for example) and then make a jpeg from that with the method above?
It wouldnt be 300 dpi, but an image that large could be converted to a 6.5" x 3" 300 dpi image. Basically the same as a digital camera, a high rez 72 dpi image.
Just have the user work on a low rez version on-screen and then from that create the very large component and save it to jpeg.
Will this even work? Im just thinking out loud.
